          New differential
          pressure transmitter for gas and compressed air applications

          
A new range
          of compact, lightweight differential pressure transmitters for
          gas and compressed air applications is now available in the UK
          from Impress Sensors & Systems Ltd.

          
The DPS 200 range
          of differential pressure transmitters is designed to operate
          with any gas or compressed air and so is ideally suited to Buildings
          Management Systems, including HVAC (Heating, Ventilation and
          Air Conditioning) systems, low differential pressure measurement
          applications and industrial clean rooms.

          
The DPS 200 comprises
          a piezoresistive pressure sensor and an optional integrated LC
          display. The unit is available in 14 nominal pressure ranges
          (differential and gauge) from 1 mbar up to 1,000 mbar. The 5-digit,
          7-segment LC display has a digit size of 8mm and a visible range
          of 32.5mm by 22.5mm.

          
Sam Drury, Sales
          & Marketing Director at Impress Sensors & Systems Ltd
          comments: “The DPS 200 is very competitively priced compared
          to alternatives that are currently available on the market. The
          units can be fitted anywhere along a pipeline or within a control
          cabinet or panel. The unit is protected by a rugged ABS housing
          to IP54 and is both compact and lightweight.”

          
The DPS 200 operates
          at a high measuring rate of 1kHz, with a response time that is
          adjustable by using a potentiometer in the range 50ms up to 2.5s.
          3-wire current or voltage outputs are available.

          
As Drury states:
          “Being able to adjust the response time is particularly
          useful if the user needs to eliminate any false triggering in
          the system. For example, if a filter somewhere in the system
          becomes blocked over time and the transmitter normally operates
          at a nominal differential pressure of 50mbar. This differential
          will increase progressively over time due to the filter blockage,
          which can cause chatter. By dampening the response time of the
          transmitter, false triggering within the system can be prevented.”

          
The DPS 200 is
          temperature-compensated in the range 0 deg C up to 50 deg C.
          The unit also provides all the required electrical protection,
          including short-circuit protection, reverse polarity and electromagnetic
          protection according to EN 61326.
