LMI pressure sensors by First Sensor/TE Connectivity
Pressure Medium: Air/Gas
Sensor Type: Differential
Supply Voltage: Under 5V
Output Signal: Digital
Pressure Range: Under 4” H2O, 4” H2O to 3 psi
Kind: Board Level

The LMI low differential pressure sensors by First Sensor/TE Connectivity are based on thermal flow measurements of gas through a microflow channel integrated with the sensor chip. 

The innovative LMI technology features superior sensitivity especially for ultra low pressures. The extremely low gas flow through the sensor ensures high immunity to dust contamination, humidity and long tubing compared to other flow-based pressure sensors.
