WSERD-134.446<\/h1>\n

Elektronischer Luftstromw\u00e4chter f\u00fcr Wandmontage.<\/h2>\n
<\/div>\n
Der Luftstromw\u00e4chter WSERD ist f\u00fcr die \u00dcberwachung von Ventilatoren, Stellklappen, Befeuchtern und elektrischen Heizregistern gem\u00e4\u00df DIN 57100, Teil 420 sowie zum Einsatz mit DDC-Anlagen geeignet. Der Luftstromw\u00e4chter arbeitet nach dem kalorimetrischen Prinzip. Hierbei wird der Entzug von W\u00e4rme durch die Luftstr\u00f6mung gemessen und in den Schaltwert umgerechnet. Der F\u00fchler enth\u00e4lt dazu ein Heizelement und zwei Temperaturf\u00fchler. Ein Mikrocontroller steuert die Heizung und misst die Temperaturunterschiede. Aus den hinterlegten Kalibrierkurven berechnet er die Luftstr\u00f6mungsgeschwindigkeit und \u00fcbertr\u00e4gt den Wert seriell an das Steuerger\u00e4t. Hier ermittelt ein weiterer Mikrocontroller aus den Vorgabewerten der Einstellregler das Schaltverhalten der beiden Relais. Die Montage erfolgt mit geeigneten Schrauben (nicht im Lieferumfang enthalten) auf ebenen Untergrund und ist lageunabh\u00e4ngig.<\/div>\n
