1. Sensor scale:
1) Normal use (static experiment or quasi-static experiment, when the frequency of application is not high, the scale of the sensor should be selected to consider the measured force value, as well as the component of the auxiliary tool (test fixture), etc.).
2) When used dynamically, the scale of the sensor is generally greater than 3-5 times of the measuring force.
3) When the maximum output of the equipment (servo motor, cylinder output, etc.), the influence of the pulse on the sensor needs to be considered. As a result, the sensor is more than twice as large as an overshoot.
2. Accuracy of the sensor:
1) The accuracy of the sensor should be selected according to the requirements of the load cell in the measurement system.
2) The induction accuracy of the sensor: &=(V (RL2+ RR2+ RH2+CP2)/4, the linearity, hysteresis, refoldability, creep and sensitivity of the sensor affect the induction value, and the induction accuracy of the sensor is 2-3 times the accuracy of the system.
3) Sensor sensitivity S, confirm sensor resolution and system resolution.
3. Anfang method:
1) Fixing method: thread, plane, accessories, etc.
2) Installation space: Confirm the ruler requirements of the sensor: length, width, outer diameter, etc.

Differential pressure sensor function – ifm sensors
A differential pressure sensor is a sensor used to measure the difference between two pressures, usually used to measure the pressure difference between the front and rear ends of a device or component.
A typical application of differential pressure sensors is to measure the difference in exhaust pressure between the front and rear channels of the exhaust particulate trap of a passenger car engine.

Ultrasonic sensor ranging principle
Ultrasonic sensors are sensors that convert ultrasonic signals into other energy signals, usually electrical signals. Ultrasonic waves are mechanical waves that oscillate at frequencies higher than 20KHz. It has high frequency, short wavelength, small diffraction phenomenon, especially good directionality, can become a ray and directional propagation, etc.
