Features • Pressure range: 0kPa~35kPa...2MPa • Constant Current / Constant Voltage Power Supply • No O-rings, all welding construction, possible for various fliud media • Stainless steel 316L • High static pressure 20MPa • Wide temperature compensation: 0°C~70°C • Pressure port (optional) • 1.5 times overpressure Application • Industrial process control • Differential pressure measurement • Gas, liquid pressure measure • Pressure checking meter • Pressure calibrator • Ventura and eddy-current flow meter Introduction MDM291 piezoresistive differential pressure transducer is an OEM differential pressure measuring element using stainless steel isolated diaphragm, all welding construction and having no O-rings. It has unified construction, high static pressure, good stability and reliability. 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 chooses high accuracy and high stability silicon die. It achieves precise differential pressure measurement. The transducer 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. Electric connection: 100mm silicon rubber flexible wire Common Mode Voltage Output: 50% input (typ.) Input impedance: 2kQ - 8kQ Output impedance: 3.5kQ - 6kQ Response (10%-90%): <1ms Insulation Resistor: 100MQ,100VDC Overpressure: refer to Order Guide Max static pressure: 20MPa Zero drift/ Static pressure: <0.5mV/MPa MICRO SENSOR CO.,LTD Construction Performance Diaphragm: stainless steel 316L Housing: stainless steel 316L http://www.microsensor.cn Add: No.18,Yingda Road Baoji,P.R.China, 721006
