The micro differential pressure transmitter measures very low pressure differences of air and neutral, non-flammable gases in HVAC, cleanroom and ventilation systems. It combines a high-stability MEMS micro differential pressure sensor with an integrated LCD for local readout.
Outputs include 2-wire 4 to 20 mA, 3-wire 0 to 10 V and RS-485 with Modbus RTU. A zero button and adjustable damping simplify commissioning, and the flame-retardant PC housing with IP65 protection is designed for wall or duct mounting.
Key features
