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.

Order Note
1. Please notice that one side of the leading wire is High Pressure Side, the other is Low Pressure Side. Or identify High Pressure Side by mark "+", and identify Low Pressure Side by mark "-" carefully. During application, please pay attention that the pressure of high pressure side should be higher than that of low pressure side;
2. Please pay attention to protect the diaphragm, prevent it from damaging;
3. Please do not pull the 6 leading wires.
4. Temperature resistant range of standard Viton O-ring of sensor is -20ºC ~ 250ºC. When working temperature is lower than -20ºC, or sensor is applied in critical environment.
