Introduction
MDM290 piezoresistive differential pressure sensor is OEM differential pressure sensor with
stainless steel isolated diaphragm. It has integrated construction, high static pressure, high stability and
good reliability. The high and low pressure sides are protected by isolated diaphragm. It can be used for
measuring corrosive and conductive flow media. The measured differential pressure is transmitted onto
the die through the diaphragm and filling silicon oil, so that the sensor could measure differential pressure
precisely. The sensor is tested on the advanced production line, with the popular dimension, MDM290
differential pressure sensors are widely used for industrial process control and differential pressure
measure fields, etc.
