Description
MRD26 series is a rugged silicon Piezo-resistive technology based differential pressure transmitter
suitable for pipe lines and process control systems. This compact differential pressure transmitter offers
great flexibility and reliability for a wide range of applications with highly competitive pricing.
MRD26 is available in pressure ranges from 0.01 to 6bar with an output of mA, V and frequency output
(option). It is suitable for pressure measurement of non-conductive, non-corrosive and non-viscous
liquids and gases. 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 process control systems among many others.
The robust construction of MRD26 with its high performance makes it ideal for demanding long term
applications.
