Differential pressure transmitter / piezoresistive / RS485 / Modbus

HK INSTRUMENTS DPT-Dual is basically a field adjustable differential pressure transmitter with two pressure sensors for air. It houses an input terminal for two analog inputs and external signal conversion into Modbus.

The incorporated measuring element is Piezoresistive with a wide range of measuring units(Pa, kPa, mbar, inchWC, mmWC, psi) and promises an accuracy of ±1.5 % +1 Pa. The unit uses a supply voltage of 24 VAC or VDC ± 10 %, power consumption of
The housing is with ABS with polycarbonate covers, brass made pressure connections, ABS duct connectors and PVC piping. The structure is robust, measures about 102.0 x 71.5 x 36.0 mm and offers long durability. The unit is IP 54, EMC, CE, RoHS compliant and operates at a temperature range between -10 to +50 °C.
