MRA23

OEM Strain Gauge Pressure Sensor

MRA23 series with 17-4PH diaphragm is a rugged strain gauge based pressure sensor suitable for harsh environments. The strain gauge design of this pressure sensor offers great flexibility for OEM applications with highly competitive pricing.
MRA23 comes in a range from 20bar to 1500bar with an output of mV/V. It is suitable for pressure measurement of gases & liquids compatible with stainless steel 17-4PH. 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 MRA23 with its high performance makes it ideal for demanding long term applications.
