MRQ21

High Temperature Pressure Transmitter

MRQ21 series with SS316L diaphragm is a rugged Silicon On Isolation (SOI) technology based pressure
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.
MRQ21 is available in pressure ranges from -1 to 1000bar with an output of mA or V. It is suitable for
pressure measurement of gases & liquids compatible with stainless steel. While the standard precision is
0.5% FS, you can optionally get a precision of 0.25% FS.
The robust construction of MRQ21 with its high performance makes it ideal for demanding long term
applications.
