|
The silicone diaphragm with resistive sensor is subjected to the pressures that are to be measured, on on each side. The resistance changes with the flex of the diaphragm and is converted to a signal in an integrated amplifier. The output signal, which is temperature compensated, is linear within the measurement range.
