          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.
