Load cells and load cells In a strict sense, load cells are just one type of load cell. The load cell can only measure the force perpendicular to the horizontal plane to the center of the earth, so it is generally applied to the scale. Other force sensors can measure the force in any direction, so the application range is wider. Diffused Silicon Pressure Sensor The diffusion silicon Pressure Sensor adopts the diffusion silicon piezoresistive pressure sensor with stainless steel isolation film as the signal measuring element, the signal processing circuit is located in the stainless steel housing, the sensor signal is converted into standard 4-20mA current or RS485 signal output through the professional signal conditioning circuit. Widely used in petroleum, chemical, metallurgy, electric power and other industrial process on-site measurement and control.

The working principle of the load cell (load cell) is that the sensor works according to the principle that the resistance of the silicon chip is increased when the device is flexed by any external force. The sensor uses a stainless steel "target=_blank> stainless steel ball to concentrate the applied force directly onto the silicon-sensing element. The change in resistance value is proportional to the magnitude of the applied force. The change in circuit resistance causes the mV output to be converted. Ping also made corresponding changes.
Load cells (load cells) are mainly used in medical infusion pumps, movable non-inverted pressure pumps, plug detection, kidney dialysis machines, load and pressure sensing, variable tension control simulation, robot end sensing And wire welding equipment and many other occasions.
Load cell (load cell) classification: generally divided into S-type load cell (load cell) and spoke type load cell (load cell)
The S-type load cell (load cell) is characterized in that the sensor elastomer adopts a shear or curved cantilever beam structure, one end is fixed, one section is stressed, the shape height is low, the structure strength is high, and it can be used for various tensile forces and pressures. Force bearing and measurement. It has the characteristics of dustproof seal, wide measuring range, high precision, stable and reliable performance, convenient installation and use. It is suitable for industrial automatic measurement and control systems for various weighing and weighing of electronic scales and weighing instruments.
The spoke type load cell (weighing sensor) is characterized in that the elastic body adopts a short and high shear beam, the rigidity is excellent, the lateral force is strong, and the structure has overload self-locking. The protection is sealed with plastic seals and IP68, which are IP67 and IP68 respectively. Therefore, it is widely used in truck scales, balances, dynamometers and crane scales.
