Ait Flow Rate Sensor AWM Series Honeywell

Product Description

This air flow sensor works according to the principle of the hot film anemometer & uses the cooling effect over the surface of the sensor element striking air current The output voltage changes in equal measure like air or gas flow by inlet & discharge openings of the sensor casing. Constructed with thin film, thermal insulated bridge structure with heat & two temperature sensor elements The bridge structure makes possible high measuring sensitivity as well as fast response time on air/gas flow over the chip. The two temperature sensors with central heating element lying between them make possible the detection of the direction of current & the measurement of the flow Made from two existing Wheatstone bridges, passive element
