MDM291 Differential Pressure Transducer - 1

MDM291 Differential Pressure Sensor MDM291 Differential Pressure Sensor Features · Pressure range: 0kPa～35kPa…2MPa · Constant Current Power Supply · O-rings, all welding construction, possible for various fluid media No · 316L stainless steel · High static pressure 20MPa · Wide temperature compensation: 0℃~70℃ · Pressure port (optional) Application · Industrial process control · Differential pressure measurement measure · Pressure checking meter · Pressure calibrator · Ventura and eddy-current flow meter Introduction MDM291 piezoresistive differential pressure sensor is an OEM differential pressure measure element using stainless steel isolated diaphragm, all welding construction and having no O-rings. It has unified construction, higher static pressure, good stability and reliablity. The high and low pressure sides are both protected by isolated diaphragm and welded with male screw thread pressure port, therefore the two pressure sides are both possible to corrosive and conductive liquid media. The measured pressure is transmitted onto the die through isolated diaphragm and filling silicon oil. The sensor element choose high accuracy and high stability silicon die. It achieves precise differential pressure measurement. The sensor is produced in advanced production line, through automatic computer testing and temperature compensation, so it has good temperature feature. It can be widely used in industrial process control field etc. for differential pressure measurement. Specification Power supply: ≤2.0mADC Electric connection: 100mm silicon rubber flexible wire Common Mode Voltage Output: 50% input (typ.)
