Pressure transmitters

GEORGIN uses the piezo-resistive effect sensor principle to make these products.
The distortion under pressure of a sensing element results in resistance fluctuations of a WHEATSTONE strain gauge bridge screen printed on a ceramic support. This type of sensing element is commonly called a thick film strain gauge.

Under the effect of pressure a distortion is caused. This one leads to proportional variations in the resistance bridge to obtain a 4 to 20 mA electric signal.
These pressure transmitters generally use a cylindrical format, with fixed range, 0.5% accuracy class and are not configurable.

Process pressure transmitters
Using leading edge technology in silicon chip manufacturing, ProcessX transmitters incorporate a high performance micro capacitance silicon sensor.

The differential pressure is applied to the silicon sensor and changes the two capacitance values (C1 and C2) of the sensor as a function of the measured pressure.
The silicon chip is assembled floating in the measuring cell neck and improves the static pressure and temperature stability characteristics.
The SMART pressure transmitters of this family are rangeable and offer a high level of accuracy (<0.1% class).
