|
The silicone diaphragm with the resistive sensor section is exposed to the pressures to be measured, one on each side. The resistance changes as the diaphragm bends and the signal is subsequently converted in an integrated amplifier. The output signal, which is compensated for temperature, is linear within the measuring range.
