Function Introduction

The BM01 thin film pressure sensor can be used for static and dynamic pressure measurement of any contact surface. The thin film pressure sensor converts the pressure applied in the sensor sensing area into resistance signals, and then obtains information about the change of external pressure according to the calibration curve of the force-resistance relationship. The greater the pressure, the smaller the output resistance of the sensor Is equivalent to varistor. When the pressure sensor is free of external load, the circuit is in a high resistance state. When external pressure is applied to the sensor, the circuit resistance decreases. The pressure and the resistance are in reverse ratio, and the relationship between the pressure and the conductance is linear, so the pressure change can be inversely deduced according to the conductance change.
