1. Sensor scale:
(1) In normal use (static test or quasi-static test, the frequency of use is not high), the scale of the sensor should be selected to consider the force value of the measurement, but also to consider the weight of the auxiliary tool (test fixture), etc., the general selection of the sensor scale is (measurement + tool) × 1.2-1.5 times.
(2) When used dynamically, the scale of the sensor is generally selected to be 3-5 times greater than the measuring force.
(3) Considering that when the maximum output of the equipment (servo motor, cylinder output, etc.), it is necessary to consider the effect of the pulse on the sensor. As a result, the size of the sensor at the time of selection is more than twice that of an overshoot.
2. Accuracy of the sensor:
(1) The accuracy of the sensor should be selected according to the requirements of the measurement system for the load cell.
(2) The induction accuracy of the sensor: &=(√(RL2+RR2+RH2+CP2))/4, the linearity of the sensor, hysteresis, repeatability, creep, sensitivity temperature affect the induction value, and the induction accuracy of the sensor is 2-3 times higher than the system accuracy.
(3) Sensor sensitivity S, confirm the resolution of the sensor, and confirm the system resolution.
3. Device method:
(1) Fixing method: thread, plane, accessories and other fixing methods.
(2) Device space: Confirm the size requirements of the sensor: length, width, outer diameter, etc.
4. Stress method:
Point force, surface force, through-hole force, tensile force, torque measurement, torque, multi-component force, etc.

Three major load cells – ifm sensors
1. Resistance strain gauge
The resistance strain gauge is a resistance wire mechanically distributed on a substrate made of organic materials, that is, it becomes a strain gauge. An important parameter for him is the sensitivity coefficient K. When his ends are subjected to the F force, they will elongate, that is, they will be deformed. ...

Precautions for the selection of level transmitters – ifm
The differential pressure transmitter is a transmitter that measures the pressure difference between the two ends of the transmitter, and outputs a standard signal (such as 4-20mA, 1-5V). The difference between the differential pressure transmitter and the general pressure transmitter is that they have 2 pressure interfaces, and the differential pressure transmitter is generally divided into positive pressure end and negative pressure end.

The solution to the non-output of pressure transmitters – ifm
1. If the pressure transmitter is used in cooperation with the digital display, if the digital display does not appear at this time, then the user may say that the pressure transmitter has no output, but in fact, this problem is obvious, and it is unreasonable to hastily determine that the pressure transmitter has no output. If the pressure transmitter is working properly, ...

Sensor performance indicators – ifm
Selection of sensitivity
In general, within the linear scale of the sensor, the higher the sensitivity of the sensor, the better. Because as long as the sensitivity is high, the value of the output signal corresponding to the measured change is relatively large, which is conducive to the signal processing.
