    MRB28

    General Purpose Piezo-resistive Digital Pressure Transmitter

    MRB28 series with SS316L diaphragm is a rugged silicon Piezo-resistive technology based pressure transmitter suitable for harsh environments. This compact pressure transmitter offers great flexibility and reliability for a wide range of applications with highly competitive pricing. MRB28 is available in pressure ranges from -1 to 0bar and 0 to 1000bar with an output signal of 4-20mA. It is suitable for pressure measurement of liquids compatible with stainless steel. While the standard Precision is 0.5% FS, you can optionally get a precision of 0.25% FS and 0.1% FS. The robust construction with its high performance makes it ideal for demanding long term applications.
