MRF21

Flush Diaphragm Piezo-Resistive Pressure Transmitter

MRF21 series with SS316L flush membrane is a Piezo-resistive silicon technology based pressure transmitter. This compact pressure transmitter offers great flexibility and reliability for a wide range of
applications in many industries such as food, beverage and pharmaceutical with competitive price.
MRF21 is available in pressure ranges from -1 to 350bar with an output of mA or V. It is suitable for pressure measurement of gases & liquids compatible with SS316L. While the standard Precision is
0.5% FS, you can optionally get a precision of 0.25% FS.
The robust construction of MRF21 with its high performance makes it ideal for demanding long term applications.
