Description

MRF25 series with SS316L flush membrane is a rugged silicon

technology based pressure transmitter suitable for harsh environments. This compact pressure

transmitter offers great flexibility and reliability for a wide range of applications in many industries such as

water, food, beverage and pharmaceutical with competitive price. 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.

MRF25 is available in pressure ranges from -1 to 350bar 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. The robust construction of MRF25 with its high performance makes it ideal for

demanding long term applications.
