The Deltapi N series pneumatic transmitters provides a standard output pressure signal from a variety of inputs: flow, pressure, differential pressure or level of liquids, steam, gas or air. The transmitter may be divided into two main units: the measuring unit, which detects the measuring value and the transmission unit containing the pneumatic transducer. The transmission unit is common to all the models. All working parts are completely protected by a weatherproof housing.
