| The pressure transmitter 2012/3 is suitable to measure liquid, gas, or steam flow as well as liquid level, density and pressure. 2012/3 outputs a 4 to 20 mA DC signal corresponding to the measured pressure. The key features include quick response, remote set-up using communications, self-diagnostics and optional status output for pressure high/low alarm. |
 |
The gauge/absolute pressure transmitter includes two functional units:
—Main unit
—Auxiliary Unit
The main unit includes a sensor and process connection. The completely welded sensor module is a twin-chamber system with an integral overload diaphragm, a temperature sensor and the silicon gauge/absolute pressure sensor. The temperature sensor as a temperature compensated reference value to compensate for the temperature drift. |
