AI Technical Summary
Pressure sensors with monolithic bodies and sealingly applied membrane elements can experience excessive flexure due to fluid pressure, leading to imprecise pressure detection without sensor failure, as the membrane may contact the lower face, causing errors in pressure measurement.
A pressure sensor design featuring a sensor body with two parts joined by a fixing material, where one part defines the membrane portion and the other supports a deformation-detection circuit, with a circuit element that interacts with the detection circuit upon excessive flexure to distinguish excessive pressure conditions, modifying the output signal to prevent measurement errors.
The solution enables precise discrimination of excessive fluid pressure, preventing measurement errors by modifying the output signal when the membrane contacts the sensor body, thus ensuring accurate pressure detection within the nominal working range.
