Pneumatic pressure sensor for measuring very low gauge reference pressures with ranges starting from 10 mbar (4 inH2O) up to 1000 mbar (400 inH2O) gauge. Ideal for use on pneumatic control systems, heating, ventilation and air conditioning systems (HVAC) and computer equipment rooms.
The DMP343 pneumatic pressure sensor uses a highly linear exposed piezoresistive silicon element to measure the pressure of air, gases and non-aggressive low viscosity fluids. Using an exposed silicon diaphragm increases its sensitivity and improves the performance at very low pressures.
An amplified voltage, 2 wire current or 3 wire current loop output signal format. There is also the option for ATEX approved intrinsic safety with the 2 wire 4 to 20 mA version.
