266DSH - Differential Pressure Transmitter

Model 266DSH is the most common type of differential pressure transmitter which widely used in different industries. It is suitable for measuring liquid, gas or steam lines differential pressure as well as measuring differential pressure caused by flow primary elements to calculate volumetric or mass flow rate.

The long-term stability and its proven reliability make of 266DSH the best application solution for gauge pressure measurements. This transmitter features in-field replaceable electronics module that thanks to the auto-configuration functionality dramatically improves plant productivity.
