DPT-Priima-MOD
High accuracy transmitter with Modbus communication and air flow measurement
DPT-Priima-MOD is a multifunctional high accuracy differential pressure transmitter with Modbus communication and air flow measurement. It is designed for cleanrooms and other demanding applications. DPT-Priima-MOD has a new, extremely accurate sensor and automatic zero point calibration, and optional calibration certificate.
The DPT-Priima-MOD is used for measuring differential pressure and air flow in building automation, HVAC and cleanroom systems. It can also be used with several different measurement probes such as FloXact
or pitot tube, and air dampers. The most common applications are pressure monitoring in cleanrooms and over the building envelope.
