About the MDM290 Differential pressure sensor module
The MDM290 is an OEM differential pressure sensor featuring a stainless steel isolated diaphragm. It has an integrated construction, offering high static pressure, stability, and reliability. Both the high and low-pressure sides are protected by isolated diaphragms, allowing it to measure corrosive and conductive fluid media. The differential pressure is transmitted to the die through the diaphragm and filling silicon oil, ensuring precise measurements. The sensor undergoes automatic testing and compensation for zero and temperature performance using provided resistors. Its installation dimensions are consistent with general products, ensuring excellent interchangeability. It is widely used in industrial process control and differential pressure measurement fields.
