MRD21 Differential Piezo-Resistive Pressure Transmitter Features High Measuring Accuracy Differential Pressure Measurement Range of 0.1 to 35bar Compact and Rugged Model Wide Range of Media Compatibility Low Static and Thermal Errors Description MRD21 series with SS316L diaphragm is a rugged silicon MEMS technology based differential pressure transmitter suitable for harsh environments. This compact differential pressure transmitter offers great flexibility and reliability for a wide range of applications with highly competitive pricing. MRD21 is available in pressure ranges from 0.1 to 35bar with an output of mA or V. It is suitable for pressure measurement of gases & liquids compatible with SS316L. While the standard Precision is 0.5% FS, you can optionally get a precision of 0.25% FS and 0.1% FS. It finds applications in hydraulic and pneumatic systems among many others. The robust construction of MRD21 with its high performance makes it ideal for demanding long term applications. Applications Hydraulic systems Fire control systems Pump controls Manufacturing automation Pneumatic systems Hydrology research Manufacturing process controls Hydro balancing systems Technical Specifications Pressure media: gas or liquid compatible with SS316L Compensated temp range: 0~+70°C Long term stability: <0.2% FS/year Temp. coefficient of zero: 0.03% FS /°C Overpressure rating: 200% FS (for positive pressure side) and 100% FS (for negative pressure side). For the range>10bar, the max. overload of the negative side is 10bar. Temp. coefficient of span: 0.03% FS /°C Process connection: G1/4 or others Precision: 0.5% FS (standard), 0.25% FS, 0.1% FS(range>1 bar); combined LRH errors System Pressure Effect: 0.05% FS/bar MeasureX Pty Ltd U14, 42 Garden Boulevard, Melbourne VIC, 3172, Australia Operating temp range: -20~+80°C Insulation resistance: 100MΩ @ 50VDC Electrical connection: DIN43650 and others Sealing: n-Butyronitrile or fluoro-rubber sealing ring Tel: +61 3 9558 2420 email: Sales@MeasureX.com.au Website: www.MeasureX.com.au
