MRB21 General Purpose Pressure Transmitter for For 3 to 20VDC Input Voltage Features High Measuring Accuracy Pressure Measurement Range of -1 to 600bar Compact and Rugged Model Wide Range of Media Compatibility Low Static and Thermal Errors Reverse polarity and transient current protected Description MRB21 series with SS316L diaphragm is a rugged silicon technology based pressure transmitter suitable for harsh environments. This compact pressure transmitter offers great flexibility and reliability with highly competitive pricing. The 3 to 20VDC input voltage enables the transmitters to be used in portable applications such as agricultural machinery and automotive testing. It finds a wide range of applications due to its compatibility with different data loggers. MRB21 is available in pressure ranges from -1 to 600bar with an output of VDC. It is suitable for pressure measurement of gases & liquids compatible with SS316L. Options for Titanium, Hastelloy or Tantalum diaphragm are available on request. 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 of MRB21 with its high performance makes it ideal for demanding long term applications.
