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.
