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.
