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.
