MRH21 High Frequency Pressure Transmitter Features Frequency Response up to 1MHz High Measuring Accuracy Pressure Measurement of -1 to 1000bar Low Static and Thermal Errors Compact and Rugged Model Wide Range of Media Compatibility Description MRH21 series with embedded amplifier circuit is a rugged MEMS technology based pressure transmitter suitable for dynamic measurements. This compact pressure transmitter offers great flexibility and reliability for a wide range of applications at highly competitive pricing. MRH21 is available in pressure ranges from 0.1 to 1000bar with voltage output. It is suitable for pressure measurement of gases & liquids compatible with stainless steel. While the standard Precision is 0.5% FS, you can optionally get a precision of 0.25% FS. The robust construction of MRH21 with its high performance makes it ideal for demanding long term applications. Applications Production machinery Aerospace and military industries Machine tool control Data logging Hydraulic equipment Technical Specifications Pressure media: all fluids compatible with stainless steel SS321 Dynamic frequency response: 1MHz max.
