Product Description

The DMP 331 precision pressure transmitter is a silicon strain gauge based sensing device with high repeatability and low pressure hysteresis measurements.  The silicon chip is isolated from the pressure media by a thin stainless steel membrane and silicone oilfill.

The high sensitivity of silicon semiconductor strain gauges facilitates low pressure ranges down to as low as 0 to 100 mbar and because of the metal capsule construction it is compatible with wet media.

The electronics offer flexibility of output along with improved linearisation options for better measurement accuracy.

The DMP331 has been hazardous zone approved for use in work areas that may contain flammable or dusty atmospheres.  There is also the option for SIL2 approved eletronics where more stringent reliability and safety is required.
