Modbus differential pressure transmitter DPT-MOD
HK Instruments DPT-MOD
The DPT-MOD is a multifunctional transmitter for measuring volumetric flow rate, velocity, and static and differential pressure. Measurements can be read and configuration is performed via Modbus communication.
The DPT-MOD requires less wiring than traditional 3-wire transmitters, as it allows multiple devices to be connected in the serial line. Furthermore, the DPT-MOD is compatible with various measuring probes, such as FloXact™, Pitot tubes, and air dampers.
