MDM291
Used For
Industrial Process Control, Pressure Checking Meter, Pressure Calibrator
Leave a MessageMDM291 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.
Features
• Isolated structure without "O" type sealing ring
• All 316L stainless steel material
• High static pressure 20MPa
• Wide temperature compensation range 0℃~70℃
• Pressure port thread optional

To accurately obtain information about fluid properties, oil layer depth, and other parameters during exploration and extraction, it is necessary to measure formation pressure, fluid density, temperature, and other factors. These data can be remotely transmitted to an online dispatch platform, connected with other oil and gas wells, and integrated into a dedicated IoT network for the oil field. This enables automatic data collection and remote control of oil well production, achieving unified scheduling and intelligent management of oil well production.
