Description
MRD23 series with SS316L diaphragm is a rugged Piezo-resistive silicon technology based differential
pressure sensor suitable for OEM applications and harsh environments. This compact differential
pressure sensor offers great flexibility and reliability for a wide range of applications with highly
competitive pricing.
MRD23 is available in pressure ranges from 0.35 to 35bar with an output of mV/V. It is suitable for
pressure measurement of gases and liquids compatible with SS316L. While the standard precision is
0.5% FS, you can optionally get a precision of 0.25% FS. It finds applications in hydraulic and pneumatic
systems among many others.
The robust construction of MRD23 with its high performance makes it ideal for demanding long term
applications.
