Features 【Reset Switch】 The reset switch enables the detector to be manually reset during commissioning and testing. This results in the detector re-tuning the sensing loop and becoming ready for vehicle detection . 【Stable Performance】Internal circuit adopts high quality electronic components, with stable performance. Industrial grade manufacturing, includes red output light indication and green power light indication for high safety. 【Sturdy】Compatible with all kinds of road gates in car parks, anti-interference and good stability. Use temperature up to 85 ℃, our vehicle loop detector after precision calculations, many times test in -40 ℃ throw can work normally. 【Sensitivity adjustment】The sensitivity is adjusted using the slide switch on the top panel, with three levels: H for high sensitivity, M for medium sensitivity and L for low sensitivity. In the trial run, first set the sensitivity to a lower gear, after the actual test if the vehicle detection does not respond, then the sensitivity should be adjusted up a gear, so repeatedly, until the vehicle detector is stable and normal work. 【Application】The Vehicle Detector is mainly used to detect the existence and passing of vehicles. Widely used in parking lots of shopping malls, hotels, company, residence, etc. Excellent for highways, electronic police, traffic lights, traffic flows monitoring, community buildings and other types of car parks.
