Details
MRA21 series with SS316L or hastelloy diaphragm is a rugged Piezo-resistive silicon technology based pressure sensing element suitable for OEM applications in harsh environments. This compact pressure sensor offers great flexibility and reliability for a wide range of applications with highly competitive pricing.
MRA21 is available in pressure ranges from -1 to 1000bar with an output of mV. 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 MRA21 with its high performance makes it ideal for demanding long term applications.
