Product Details



1.Introduction and principle :

 AT3051 Metal capacitive sensor is the very important accessory for the pressure transmitter performance . Outside pressure /differential pressure make the capacitance value change of the transmitter, the digital signal transfer into 4-20mA current output, the microprocessor process the data (display and set), the interface used for digital communication, HART module can be used for Hart communication.

The medium pressure is transferred to the test diaphragm in the middle of δ room by the barrier diaphragm and Silicon oil, as the test diaphragm is tight flexible element, it produce displacement following the pressure differential. The displacement of the diaphragm and pressure differential are in direction proportion, the max displacement is 0.1mm, It is tested by the by the capacitive plat on the both side, Then the differential capacitor between the test diaphragm and capacitive board switched to standard output by the Circuit Current.
