Details
MRB23 series is a rugged piezoresistive silicon technology based pressure transmitter specially designed for applications where economical price and accurate pressure measurement is required. Mass production of the housing and circuitry makes it cost effective for high volume O.E.M applications.
The housing and the wetted parts are made of 304 stainless steel and the pressure membrane is made of SS316L. The users can choose accuracy of 0.5% (standard) or 0.25% for high accuracy requirements.MRB23 is available in pressure ranges from -1 to 1000bar with an output of mA or V. This model is ideal for general industrial applications, which is notable for its compact design and also offers excellent quality at an extremely competitive price.
