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.
Pressure Ranges: from 10 to 1000 mbar, -1000 mbar vented gauge
Accuracy: 0.35% FS NLHR > 100 mbar, 0.5% FS NLHR <= 100 mbar, IEC60770
Output Signals: 0-10V, 4-20mA 2 wire and 0-20mA 3 wire
Electrical Connections: DIN plug, IP67 cable gland, Binder or M12
Pressure Connections: G1/2, G1/4 with DIN3852 or EN837 thread styles, 1/4 or 1/2 NPT male
Media Compatibility: Stainless steel 316L for the pressure port. Stainless steel 316L, RTV, ceramic, mineral glass and silicon for the sensing element. FKM (Viton) for the internal seals
Special Features: Low gauge pressure ranges and low cost
Special Options: Ex certification for intrinsically safe use
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
