The MDM290 differential pressure sensor is piezoresistive and oil-filled type, isolated by a stainless steel corrugated diaphragm. As differential pressure sensor suppliers, Micro Sensor`s pressure-sensitive components are assembled on advanced production lines, automatically tested and compensated by computer. The high and low-voltage ends are protected by isolation diaphragms. Both pressure chambers can be in contact with certain corrosive fluid media. The installation dimensions align with typical products, ensuring that the MDM290 sensor offers excellent interchangeability. MDM290 can be as an air differential pressure sensor for different gases. It is widely used in industrial process control and other fields to measure differential pressure.

MDM291 water differential pressure sensor is a fully welded sensor. The product has undergone automatic testing and temperature compensation process in the production process, so that the product has good temperature characteristics. MDM291 selects silicon chips with high precision and high stability. The measured differential pressure is transmitted to the sensitive chip through the pressure port, the isolation diaphragm and the filled silicone oil. This achieves a linear conversion of the differential pressure and output voltage signals. The high and low voltage ends of MDM291 are protected by isolation diaphragms. Both pressure chambers can be in contact with corrosive and conductive fluid media. The electrical connection and the high and low voltage terminals adopt threaded interface, which is convenient for assembly and installation.
