First Sensor AG products

The WBI sensors with I²C bus interface offer mass flow measurement for air and gases based on a highly sensitive thermal measuring principle. The WBI series includes unidirectional as well as bidirectional flow ranges. The digital sensors achieve a very high accuracy over the complete measuring range in the positive as well as negative flow direction and feature fast response times and low power consumption. Typical applications include medical devices, HVAC, instrumentation as well as analytical instruments.
