Pressure Transmitter level sensor

The QXMP series Pressure Transmitters are used to measure the pressure or level of industrial liquids and gases in various tanks and other types of vessels. The EC hydrostatic pressure level transmitter consists of a piezo resistive sensor and Wheatstone bridge to directly measure head pressure exerted on the diaphragm of the EC level transmitter. When the pressure is exerted on the diaphragm, as a result of the liquid/gases level, the pressure is transferred to the Wheatstone bridge electrical circuit through silicon oil contained in the EC sensing unit. This creates a differential voltage, which is then amplified to create a variable 4-20mA output that varies as a result of the changing liquid level. In addition, a pressure transducer is available for measuring pressure in tanks or pipes and producing a variable 4-20mA output.
