GFK50風門傳感器風門傳感器
干簧管在磁場中,當磁場達到一定強度時,其中常閉觸片與原來吸合的觸片脫開、與另一常開觸片吸合,當干簧管脫離磁場時,又恢復原來的狀態。利用這個原理,將帶有干簧管的傳感器組和產生磁場的磁鋼組分別安裝在風門的門框和門的邊緣(兩者相對),利用風門位置的變化,產生開關信號,送至監控系統。
主要技術指標:
測量範圍 (0~30)mm干簧繼電器吸合輸出信號開關量
接點容量 DC36V/100mA 傳輸距離≥2km
防爆型式 Exib I 外形尺寸傳感器組件110×60×35mm
磁鋼組件 80×40×25mm重量 0.4kg
Working principle:
Dry reed pipe in a magnetic field, when the magnetic field to a certain strength, the normally closed contact with original suction line of contact release, and the other a normally open contact suction close, when dry reed pipe from magnetic field, and restore its original state. Using this principle, will with dry reed pipe sensor group and produce a magnetic field of magnetic steel groups were installed in the air door frame and the edge of the door (both relative), the use of throttle position change, produce switch signal, sent to the monitoring system.
