The VAV Press Click Board™ is a compact add-on board that contains a board-mount pressure sensor. This board features the LMIS025B, a low differential pressure sensor from First Sensor (part of TE Connectivity). It is based on thermal flow measurement of gas through a micro-flow channel integrated within the sensor chip. The innovative LMI technology features superior sensitivity, especially for ultra-low pressures ranging from 0 to 25Pa. Compared to other flow-based pressure sensors, the extremely-low gas flow through the sensor ensures high immunity to dust contamination, humidity, and long tubing.
The VAV Press Click Board™ is suitable for pressure measurements in Variable Air Volume (VAV) building ventilation systems, industrial and medical respiratory applications.
