Sell Loop Detector

 Operating voltage： 220V AC ±10%  Power Consumption: ≥5VA  Output relays: 240V/5A AC  Frequency range: 20 kHz to 170 kHz  Reaction time: 10ms  Signal holding time: Unlimited / limited when loop is permanently covered 10 minutes  Sensitivity: adjustable in 8 increments  Wiring: 50μH and 300μH. Ideal is 150μH  Loop connection wiring: Maximum length 200 meters,  twisted at least 20 times per meter  Autocorrecting time: 1to 2seconds  Operating temperature: -20°C to +65°C  Storage temperature: -40°C to +85°C  Dimensions (include pedestal ): 78x40x108 mm (L x W x H)  Net Weight （include pedestal）: 265g  Specific set the table below. In trial runs, first sensitivity in the lower stalls, the actual test vehicle detection if no response should be an increased sensitivity to stall, so repeated several times until the car seized stability for normal work.
