The depth of the internal thread of the installation with the sensor should be greater than the length of the external thread of the sensor itself, so as to avoid the sensitive diaphragm of the sensor pushing to the bottom of the internal thread, so that the sensor is affected by stress.
If the size of the internal thread has been confirmed, it is recommended that the sensor should not be screwed too deep at the time of installation, and ensure that there is a small gap between the sensitive surface of the sensor and the bottom of the internal thread.
Because the hexagonal at the front end and the end of the miniature high-frequency pressure sensor are very small, only the raw material belt is used for sealing, and it is advocated that the raw material belt is wrapped to the root of the thread close to the hexagonal part, and the raw material belt is not easy to wrap too much, so that the influence of external stress on the sensor can be reduced to a certain extent during the tightening time, so as to improve its measurement accuracy.
Small diameter high-frequency pressure sensor (Φ4, Φ5, M6) should not be installed with too much torque, can be tightened by hand, if only a little force is used with a wrench, excessive torque may cause the sensor thread cracking.

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.
