China low temperature pressure transmitter
Description :
Pressure sensors are spread over the silicon chip a Wheatstone bridge, measured medium (gas or liquid) pressure to make the bridge wall resistance value changes (piezoresistive effect), producing a differential voltage signal. This signal via a dedicated amplifier, the range corresponding to the signal into a standard analog or digital signals.
