Thermal Sensors/Air Flow Sensor Units AFS

Construction

Thermal Sensors/Air Flow Sensor Units AFS Construction


1.	Air- velocity sensor
2.	Thermal compensation sensor
3.	Control box


	Features


•	The platinum thin-film thermal sensor realizes high and long- term stability.
•	The small platinum thin-film thermal sensor and an even temperature differential operating circuit ensure a quick response.
•	The built-in temperature compensation circuit assures correct values regardless of air temperature. The air velocity sensor and air velocity temperature compensation sensor are sensors with the same characteristics to enable correct temperature compensation.
•	Products have no rotating mechanism and are resistant to vibration.
•	Products are compact and light,and are easy to be installed in equipment.


	Applications


•	Air flow control of hot water boilers.
•	Air flow control of air conditioning systems for buildings.
•	Air flow control and stoppage detection of fan mortors.
•	Air flow control of clean rooms and clean benches .
•	Air velocity and air flow control of environmental equipment and apparatuses.
•	Detection of clogging of filters.
