Differential pressure transmitter 219D

4-20 mA0-5 Vratiometric

Product description
Model 219D is a compact differential pressure transmitter derived from the 218D transducer family. It features a 316L stainless steel wetted construction with laser-welded assembly and a threaded process interface for straightforward installation. Available with male or female threads, the 219D is intended for differential pressure measurement of gases and dilute liquids. Measuring ranges cover approximately 0.1 bar up to 35 bar. Output options include analog and digital interfaces suited to smart valve integration. Accuracy reaches ±0.5% fs; a non-zero output at ZERO load facilitates diagnostics.
