Presence detector CE-L22-J9

vehicleinductivemonitoring

CE-L22-J9 is a dual channel digital inductive loop vehicle detector which can output pulse and level. It is used to identify the presence of vehicle and detect the driving direction by means of two inductive loops buried under the road. This kind of detector is applied to parking lots, highway toll stations, signal lamps controlling system, police monitoring and so on Products: Dual channel loop vehicle detector; Series: CE-L22-J9; Power supply：AC 220V±20%; Self tuning range: 20—1000uH; Signal duration：No limited; Frequency：20KHz—110KHz; Sensitivity：0.04%~1.28%，8-step 3-DIP switch selectable per channel; Response time: <100 ms; Alignment：Automatic regulation; Protection: Loop isolation transformer, IMPATT diode clamping on loop inputs and gas discharge, tube protection; Loop connection wiring: Max. length 500m, twisted at least 20 times per meter; Storage temperature：-40ºC ~ +85ºC; Operating temperature：-40ºC ~ +70ºC; Humidity：95％ max; Lightening surge：±4KV (1.2/50uS) at power supply; Pulse: ±3 KV/5KHz; Dimension：LXWXH＝86.5mmX73.5mmX36mm.
