Details
MRQ25 series with SS316L diaphragm is a rugged strain gauge technology based integrated pressure-media temperature transmitter suitable for high temperature media. It has independent outputs for both pressure and temperature.
The PT100 temperature sensor probe is welded to the front end of the process connection and comes in direct contact with the media. This ensures a highly accurate temperature measurement of the media at the point where pressure is being measured. Any temperature compensation of the pressure reading will therefore be more accurate.
MRQ25 is available in pressure ranges from 0 to 400bar with an output of mA or V and temperature range of 10°C up to 140°C. It is suitable for concurrent pressure and temperature measurement of gases & liquids compatible with stainless steel. While the standard precision for pressure measurement is 0.5% FS, you can optionally get 0.25% FS. The standard precision for temperature measurement is 0.5%FS.
