Differential pressure transmitters

Model 276 Pressure Transmitter

Model 276 Pressure Transmitter

Viatran’s proprietary technology provides an accuracy of better than ±0.15% FSO. Wetted surfaces are manufactured from 316 stainless steel allowing for better corrosion resistance. Viatran designed the “76” Series to be easily accessible in confined spaces. The X76 is supported by the process connection or by an adaptable L-shaped mounting bracket.

A quick disconnect electrical connection allows for easy setup and removal. Topmounted zero and span adjustments and an internal calibration circuit simplify field setup and provide a quick two-point calibration check.

With over twenty different electrical connections and pressure ports, as well as optional improved temperature performance and modified outputs, the 276 exceeds the most demanding application requirements.
