Description
MRO21 series with SS316L diaphragm is a rugged silicon MEMS technology based pressure transducer
suitable for harsh environments. The design of this pressure transducer offers great flexibility for
customisation for different applications with highly competitive pricing.
MRO21 is available in pressures ranges from -1bar to 600 Bar in both Gauge and Absolute versions with
an output of mV/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 and 0.1% FS. It
finds applications in hydraulic and pneumatic systems among many others.
The robust construction of MRO21 with its high performance makes it ideal for demanding long term
applications.
