Airflow Monitors,Air Flow Monitor,Air Flow Monitors,fan monitor,2011 NEW Air Flow Monitor

The airflow monitor (NC / NO) is designed to indicate the loss of air movement of a fan or filter fan. The contact detects the loss of air movement caused by fan failure or blocked filter media regardless of direction of air. Its simple mechanical operation makes it a viable alternative to electronic monitoring systems.

Technical Data

Max. airflow velocity50m/s
Contact resistance< 370mOhm (with wire)
Max. air humidity70% RH (not precipitating)
Service life> 100 000 cycles
Connection2 x single strand AWG 28, length 500mm, tip of stranded wire 5mm stripped and tinned (NC: black, NO: blue)
Mountingalternatively integrated in protective grille (see table), mounting clamp or mounting clip
Casingplastic according to UL94-HB, black
Fitting positionbidirectional tab perpendicular to airflow
Operating/Storage temperature-20 to +50°C (-4 to +122°F) / -20 to +80°C (-4 to +176°F)
Protection typeIP20
ApprovalsVDE + UL File No. E250507
NoteThe product of switching voltage and switching current must not exceed 10W. The max. voltage and max. current must not be exceeded, not even short-term (voltage/current peaks). The resulting voltage and current peaks of inductive or capacitive loads must be restricted by a contact protection circuit.
