    MRQ22

    Pressure Temperature Transmitter

    MRQ22 series with the SS316L diaphragm is a rugged piezoresistive technology-based 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 1000bar 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.
