Image is Representational - See Manufacturer Specs | This microbridge mass airflow sensor from Honeywell comes from their AWM 2000 Series of Airflow Sensors. The sensor features actual mass air flow sensing, low differential pressure sensing, bidirectional sensing capability, and has a flow range of ?200 sccm. In order to function properly, the sensor requires a heater control circuit and sensing bridge supply circuit not on board the package. AWM2100V Flow Sensor from Honeywell is a micro-bridge mass airflow sensor. Featuring two Wheatstone bridges, this Honeywell Sensor delivers stable and reliable performance. The differential amplifier of this Mass Airflow Sensor can be used to introduce gain, as well as to voltage offsets to the sensor output.Flow sensors are instruments that are used for sensing the rate of fluid flow. These sensing elements are primarily used in flow meters or flow loggers to record the flow of fluids. Some of the applications for these flow sensors are gas analyzers, low vacuum control, process control, medical respirators and ventilators, leak detection equipment, and vent hoods.
