About the MDM290 Differential pressure sensor module
The MDM290 is an OEM differential pressure sensor with stainless steel isolated diaphragm, designed for accurate and stable pressure measurements. The sensor measures the pressure difference between two ports, transmitting force through a silicon oil-filled chamber onto a piezoresistive die. This setup ensures precision, durability, and compatibility with various corrosive or conductive fluids.
Usage conditions
The sensor operates between -40°C and +125°C, with a compensated temperature range from 0°C to +50°C. Its robust construction supports 2× overpressure and a static pressure tolerance of up to 200 bar. It delivers stable output even under vibration and shock (10g RMS and 100g impact).
Possible applications
- Industrial process control
- Venturi and eddy-current flowmeters
- HVAC differential monitoring
- Liquid level measurement systems
- Pressure calibrators and check meters
- Medical and gas monitoring devices
Advantages of choosing this product
With Ø19 mm installation dimensions, dual compensation options, and up to ±0.25%FS accuracy, the MDM290 provides high interchangeability and flexibility for OEM designers. Its media-isolated design enhances safety and performance in challenging environments.
