Strain Gauges is a sensor used to measure the strain generated when an object is stressed. Strain gauges are widely used in fields such as material mechanics, structural analysis, and pressure sensors. They have the characteristics of high precision, high sensitivity, and good stability. Common strain gauges include: resistance strain gauges, pressure strain gauges, fiber optic strain gauges, capacitive strain gauges, etc. The principle of strain gauge can be understood as the relationship between elastic deformation and resistance change. When an object is acted upon by an external force, the object will undergo elastic deformation, that is, the deformation will change with the action of the external force. At the same time, the resistor sheet is affected by deformation, and the resistance value will also change accordingly. This change can be measured and processed by accessing a circuit and connecting it to an electrical signal acquisition device to obtain the magnitude and nature of the force on the object. Its working principle also involves some physical principles, such as Hooke's law and strain-stress relationship. According to Hooke's law, the deformation of an elastic body is proportional to the force exerted on it. This relationship can be realized using strain gauges. The strain-stress relationship describes the relationship between the internal strain of an object and external forces. Strain gauges can indirectly obtain the stress on an object by measuring the strain value. The working principle of a strain gauge can be simply summarized as follows: when an external force acts on an object, the object will deform, causing the resistance value of the strain gauge to change; by measuring the change in resistance value, the magnitude and direction of the force on the object can be indirectly obtained. The application of this principle can be widely used in materials engineering, civil engineering, mechanical engineering and other fields, providing important data support for mechanical property research and structural design.

Load Cells are a device used to measure and monitor the weight or mass of an object. They are widely used in industrial production, commercial retail, medical diagnosis, scientific experiments and other fields. According to different working principles and application scenarios, load cells can be divided into many types. Pressure sensor: Uses the pressure exerted by an object on the sensor to measure the weight of an object. It has the advantages of simple structure and low cost. Resistive strain sensor: The force exerted by an object on the sensor is used to deform the strain gauge, thereby changing the resistance value of the sensor, thereby measuring the weight of the object. Capacitive weighing sensor: It has the advantages of simple structure and fast response speed, and is suitable for some fields that require high weighing response speed. When a force is applied to an object, the distance between the capacitors or the dielectric constant of the medium changes, thereby changing the capacitance value and thereby measuring the weight of the object. Magnetic induction load sensor: uses the weight of an object on the sensor to change the magnetic field inside the sensor to measure the weight of the object. Ultrasonic load cell: Calculate the weight of an object by measuring the propagation time of ultrasonic waves between the object and the sensor. There are many types of load cells, and different types of load cells have their own advantages and disadvantages in different application scenarios. Choosing a suitable load cell type can effectively improve the accuracy and stability of weighing, and provide better support for applications in related fields.

Load cell sensor is a sensor device used to measure weight or mass, usually composed of a carrier, an elastomer and a sensing element. Its working principle is mainly based on the principles of elastic deformation and resistance change. First, when an object is placed on the sensor carrier, the carrier will undergo slight bending or compression deformation due to the gravity of the object. This deformation will be transmitted to the elastomer of the sensor, and the elastomer itself will have a certain deformation ability to adapt to the pressure of the object. Second, the elastomer is mounted with a sensing element, usually a resistance strain gauge or thin film sensor. When the elastomer deforms, the sensing element will also be affected and the resistance value will change. This change in resistance value can be converted into a voltage or current signal through a circuit, and then the final weight or mass value can be obtained through amplification, filtering, etc. In practical applications, load cells can output weight data by connecting to a display or controller, thereby achieving accurate measurement and monitoring of the weight of objects. Some common load cell types are: Resistive strain gauge load cell: Uses the resistive strain effect to measure the weight of an object. Commonly used ones include chip resistive strain gauge load cells and Beam Load Cells. Pressure load cell: Determine the weight by measuring the pressure generated when an object is stressed. Commonly used ones include pressure sensors and piezoelectric sensors. Magnetic induction load sensor: Measures the weight of an object by measuring changes in the magnetic field. Common ones include Hall effect load sensors and magnetoelectric sensors. Different types of sensors are suitable for different weighing scenarios and requirements.

Selecting a suitable load cell sensor is an important task, which directly affects the accuracy and stability of the weighing system. When selecting a suitable load cell sensor, several factors need to be considered, including maximum load-bearing capacity, accuracy requirements, environmental conditions, size and cost. The maximum load-bearing capacity required needs to be determined.

The maximum load capacity required needs to be carefully evaluated and a sensor selected that can meet this requirement. Accuracy requirements need to be considered. Different application scenarios have different requirements for weighing accuracy. Some applications are more sensitive to weight changes, while others are less demanding, so you need to choose a high-precision sensor or choose a relatively low-precision sensor. Third, environmental conditions need to be considered. For example, in a humid environment, you need to choose a sensor with good waterproof performance. In high or low temperature environments, you need to choose sensors that can function properly under extreme temperature conditions. Fourth, there are size issues to consider. Select the appropriate sensor according to the size of the actual application, which can be easily installed and debugged. Finally, there is cost to consider. When choosing a suitable sensor, you need to fully consider the cost factor and choose a sensor with a higher cost performance while ensuring that it meets the needs. Common load cell sensors include pressure sensors, strain sensors, electromagnetic sensors, single point load cells and digital load cells. Only by comprehensively considering these factors can the most suitable sensor be selected to provide reliable guarantee for the accuracy and stability of the weighing system.

How to install a load cell? The installation method of each load cell is unique because there are many types of sensors. When your application requires very high accuracy, long-term stability, custom specifications, or use in a changing R&D environment, please consult an engineer. In order to obtain accurate weighing results, please ensure that the load cell uses the specified weighing application. The load cell has a specified load direction, please do not apply lateral force, bending, or twisting motion on the load cell. Improper loading applications may reduce the life of the load cell and distort the correct measurement results. In pressure load applications, using a rigid design for the support structure of the load cell is better than a flexible design to achieve a uniform reduction of all supports. These supports can also distribute tension and provide a uniform contact surface. Mounting the load cell on the support structure and rigid substrate ensures that the load is evenly transferred from the bottom of the load cell to the support structure. The structure must also have the ability to support the force corresponding to the load. In order to comply with the installation of the load cell, it may be necessary to install auxiliary tools. You can ask the design engineer for help to determine the weight of each interference possibility. Special consideration needs to be given to weighing tanks, thermal expansion, monitoring levels, and horizontal movement of certain tank shapes and supporting structures to avoid measurement distortion. Your load cell support structure may require end stops to limit lateral deflection, and elastic bearings can also adjust the heat between the storage tank and the load cell. In addition, the load cell needs to be centered vertically to allow it to be stressed vertically, as shown in the following figure:

In the actual application of pressure sensors, due to the mismatch of the force-sensitive resistor and the influence of the leakage current, the zero-point drift phenomenon will occur. This phenomenon affects the accuracy of the pressure sensor to a certain extent. With the continuous expansion of the application range of the pressure sensor , The requirements for measurement accuracy continue to increase, so the correction of zero-point drift has become an important research topic. Today, when computer technology is widely used, it is possible to compensate for the zero-point drift and nonlinear software of pressure sensors. This article combines current Applying a variety of common compensation calculation methods, through programming, the pressure sensor thermal zero drift phenomenon has been compensated. The results show that the nonlinear function polynomial fitting normalization method and the neural network method fit the data with high accuracy. It has a compensation effect that cannot be achieved by other methods.

The load cell is a device that converts the mass/weight signal into a measurable electrical signal output. According to the conversion method, load cells can be divided into 8 types: photoelectric, hydraulic, electromagnetic, capacitive, magnetic pole change, vibration, gyroscope, resistance strain, etc. Among them, the resistance strain is the most widely used one. Working principle of load cell The load cell uses a metal resistance strain gauge to form a measuring bridge, and is made by the principle that the metal resistance wire stretches and becomes thinner under the action of tension, and the resistance increases, that is, the effect of the change of the metal resistance with the strain received. The load cell is a conversion device used to convert a weight signal or a pressure signal into a power signal. The construction principle of the load cell is that the metal resistance has the property of obstructing the flow of current. Generally speaking, the more slender the metal wire, the greater the resistance value. When the metal resistance wire is stretched and contracted by an external force, its resistance value will increase or decrease within a certain range. Therefore, if the metal wire (or film) is tightly attached to the measured object, when the measured object expands and contracts under external force, the metal resistance wire (membrane) will expand and contract proportionally, and its resistance value will also change accordingly. The load cell is to paste the metal resistance strain gauge on the metal weighing beam to measure the weight signal. Application range of load cell With the development of the intelligent age, load cells have been applied to almost all weighing fields, realizing accurate weighing of materials. Especially with the emergence of microprocessors and the continuous improvement of industrial automation technology, load cells have become a necessary device in process control. From the weight measurement of large tanks and hoppers that could not be weighed before, and the measurement and control of crane scales, automobile scales, etc., to the batching system for mixing and distributing a variety of raw materials, automatic detection in the production process, and control of the powder and granular material feed volume, etc., Have applied the load cell. At present, load cells are mainly used in various electronic weighing instruments, industrial control fields, online control, installation overload alarms, material testing machines, and other fields, such as electronic truck scales, electronic platform scales, electronic forklifts, dynamic axle load scales, electronic hook scales, etc., Electronic pricing scales, electronic steel scales, electronic rail scales, hopper scales, batching scales, filling scales, etc. How to choose the load cell correctly? Our main consideration is the actual working environment of the sensor, because this is related to whether the sensor can work normally, its safety and service life, and even the reliability and safety of the entire weighing instrument. On the one hand, it depends on the type of weighing and installation space to ensure proper installation and safe and reliable weighing; on the other hand, the manufacturer`s recommendations must be considered. For sensor manufacturers, it generally specifies the force and performance indicators of the sensor. , Installation form, structural form, the material of elastic body, etc., for example, aluminum alloy cantilever beam sensor is suitable for electronic price calculation scale, platform scale, case scale, etc., steel cantilever beam sensor is suitable for electronic belt scale, sorting scale, etc., steel Bridge sensors are suitable for railway scales, truck scales, etc., and column sensors are suitable for truck scales, dynamic railway scales, and large-tonnage hopper scales. Under normal circumstances, the high-temperature environment will cause problems such as melting of the coating material, open solder joints, structural changes in the internal stress of the elastomer, etc.; dust and humidity will cause short-circuit effects on the sensor; in a highly corrosive environment, it will cause the sensor elastomer Damage or short-circuit phenomenon; electromagnetic field will interfere with sensor output. Therefore, under the corresponding environmental factors, we must select the corresponding load cell to meet the necessary weighing requirements.
