First Sensor WBI series of digital mass flow sensors feature flow ranges from 200 sccm and 1 slpm, high accuracy in both of its flow ranges, a digital 12C bus interface, a fast response time, and low power consumption.
These flow sensors are ideal for integration into oxygen concentrators and conservers, ventilators, spirometers, sleep diagnostic equipment, CPAP, and machines for anesthesia delivery. They utilize a highly sensitive thermal measuring principle for the detection of even the lowest air and gas flows. Their 2.7 to 5.5 V supply and overall low power consumption make them ideal for battery powered or handheld medical devices.
