Mikroe VAV Press Click features the First Sensor LMIS025B low differential pressure sensor. It’s based on thermal flow measurement of gas through a micro-flow channel integrated within the sensor chip. The innovative LMI technology features superior sensitivity. It is ideal for ultra-low pressures ranging from 0 to 25Pa. The extremely low gas flow through the sensor ensures high immunity. This is due to dust contamination, humidity, and long tubing compared to other flow-based pressure sensors.
