Parsjahd Products - 266MST

266MST multi-sensor differential pressure transmitter

Model 266MST is a differential pressure transmitter with “multisensor technology” suitable for measuring liquid, gas or steam flow as well as level, pressure and density in applications with working pressure up to 41Mpa / 5945psi.

The unique combination of several sensor systems in a single device allows simultaneous measurement of differential pressure and absolute pressure. The sensor temperature and the absolute pressure are also used for eliminating environmental effects on the sensor. Long-term stability and proven reliability are the key-factors that make of 266MST the best choice for differential pressure measurement.
