Air flow Monitor

Airflow Monitor Air flow Monitor fan monitor Mechanical switch contact Versatile fields of application Small size Easy to connectThe airflow monitor (NC / NO) is designed to indicatethe lossof 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 Contact typereed / magnet contactNormally closed (NC)switch contact open when air is flowingNormally open (NO)switch contact closed when air is flowingMax. switching voltageNC: 240VDC (UL), 240V AC/DC (VDE) / NO: 60VDCMax. switching currentNC: DC 500mA / NO: DC 170mAMax. switching capacity10W (resistive load)Switching threshold of airflow velocity> 2.5m/s (hysteresis: > 1m/s)Max. airflow velocity50m/sContact resistance< 370mOhm (with wire)Max. air humidity70% RH (not precipitating)Service life> 100 000 cyclesConnection2 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 clipCasingplastic according to UL94-HB, blackFitting positionbidirectional tab perpendicular to airflowOperating/Storage temperature-20 to +50°C (-4 to +122°F) / -20 to +80°C (-4 to +176°F)Protection typeIP20ApprovalsVDE + UL File No. E250507NoteThe 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. DescriptionArt. No. (NC)Art.
