Application:

HQ-800 transmitter is consisted of signal changeover module and piezo resistance sersor. The core part of the sensor is the single cycrgstal silicon slice, when the wafer is pressuried, its resistance rato will have change, With the semi-conductor flat surface craft, diffuse four electric resistace on the silion wafer, which connecting into. Hirschman bridge with the action of the stable current, output the voltage signal that direct proportion with the pressure signal into the standard 4-20mA signal.

HQ-800 pressure transmitter could measure the flaids (liquid, gases and vapor ), liquid level, such parameter and so on. The instrument can change measured signal into 4-20mA standard electric signal output, which can be the input signal for indcation. Record and adjust the output. The transmitter has the advantages of small volume, light weight. Goods ability, high accuracy, good price, can be with the function of spot indicating meter, Zero point, transfer, and measuring range extend. This transmitter is safety and explosion isolation with which all the function that industry transmitter have.
