How it works

Pressure sensors are diffused silicon chip on a Wheatstone bridge , voltage resistance effect is the bridge wall resistance to change , resulting in a differential voltage signal. This signal via a dedicated amplifier , and then the voltage and current transformation, the range corresponding signals into standard 4 ~ 20mA / 0 ~ 20MA / 0 ~ 5VDC / 1 ~ 5V / 0 ~ 10VDC signal.

Application

Widely used for pressure, level measurement and process control in Petroleum, Chemical industry,
Metallurgy, Food industry
