MRQ22 Pressure Temperature Transmitter Features High Temperature Media (-40°C up to 125°C) Pressure Measurement Range of -1 to 700bar Separate Output for Pressure and Temperature Compact and Rugged Model Wide Range of Media Compatibility Low Static and Thermal Errors Reverse polarity and transient current protected Description MRQ22 series with SS316L diaphragm is a rugged integrated pressure-temperature transmitter suitable for high temperature media. This compact pressure transmitter offers great flexibility and reliability for a wide range of applications with highly competitive pricing. MRQ22 is available in pressure ranges from -1 to 700bar with an output of mA or V and temperature range of -40°C up to 125°C. It is suitable for concurrent pressure and temperature measurement of gases & liquids compatible with stainless steel. While the standard precision is 1% FS, you can optionally get a precision of 0.5% FS or 0.25% FS. The robust construction of MRQ22 with its high performance makes it ideal for demanding long term applications.
