New high pressure stainless steel differential pressure transmitters offer three-in-one capability
Instrumentation specialist Impress Sensors & Systems Ltd has launched a new range of high pressure (up to 70 bar), mechanically robust differential pressure transmitters for liquids and gases. The transmitters provide three-in-one capability, including an adjustable 4-digit LED display, a pressure transmitter and two PNP pressure switch connections.
The new DMD 831 is a stainless steel differential pressure transmitter for industrial use that incorporates two piezoresistive stainless steel sensors and stainless steel diaphragms. The transmitter is therefore suitable for a wide range of plant and process engineering applications, including HVAC, energy and laboratory applications.
Differential pressure sensors and transmitters measure the difference in pressure from one side of a diaphragm to the other or between two diaphragms. When pressure is applied, the DMD 831 determines the pressure difference between positive and negative sides and transforms this into a proportional electrical signal. Typically, this enables the measurement of pressure drop across a filter due to build up or blockages, or for measuring flow and level via a pressurised vessel.
The DMD 831 is a cost effective, compact solution for OEMs and end users across a diverse range of process control applications, including pressure control for lubrication systems, hydraulics and pneumatics, air compressors, steam, water, fuels and oils.
Sam Drury, Sales & Marketing Director at Impress Sensors & Systems Ltd comments: The robust, compact design of the DMD 831 allows it to be integrated in a diverse range of process engineering and machinery applications, particularly where the installation space is restricted. The sensors also provide a turn down capability of 10 to 1.
Seven different versions of the DMD 831 are available, with differential pressures from 0 80 mbar up to 0 70 bar. The transmitters operate in media temperatures from -40 deg C to +125 deg C. Switching accuracy is +/- 0.5% FSO according to IEC 60770. The transmitters are ingress protected to IP65.
