Introduction: MDM291 piezoresistive differential pressure transducer 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 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 sidesStable and Precise Pressure Transmitter 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 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.

Order Note:
1. High pressure side and Low pressure side are marked "H" and "L" respectively on the body;
2. During application, please pay attention that the pressure of high pressure side should be higher than that of low pressure side;
3. Please pay attention to protect the diaphragm, prevent it from damaging;
4. Please do not pull the leading wires.
