Comprising a piezoresistive pressure sensor and an optional LCD, the DPS 200 range of differential pressure transmitters from Impress Sensors & Systems is designed to operate with any gas or compressed air. They are also suitable for building management systems, including HVAC systems, low differential pressure measurement applications and industrial clean rooms. 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 LCD with an 8 mm digit size has a visible range of 32.5 by 22.5 mm. Protected by a rugged IP 54ABS housing, the sensor can be fitted anywhere along a pipeline or within a control cabinet or panel. It operates at a measuring rate of 1 kHz, with a response time that is adjustable by using a potentiometer in the range 50ms up to 2.5s. A 3-wire current or voltage outputs are available. The adjustable response time is particularly useful if the user needs to eliminate false triggering in the system. Temperature-compensated in the range 0 up to 50⁰ C, the unit also provides all the required electrical protection, including short-circuit protection, reverse polarity and electromagnetic protection according to EN 61326.
