according to DIN 19259
Application Measurement of absolute and gauge pressure in gases, vapours, liquids and dusts
Operation and System Design Measuring principle
Piezoresistive sensor with diaphragm seal The process pressure acting on the diaphragm of the
diaphragm seal is transmitted to the metal separating
diaphragm of the sensor by a filling fluid. The separating
diaphragm is deflected and the resulting pressure
proportional change in the output voltage of the resistance
bridge is then measured and evaluated.
Working volume: smaller than 1 mm
