Features Vehicle loop detectors are mainly used to detect the presence of and passing vehicles. Filter option: This relay is typically used to prevent false detection of small or fast moving objects. Reset switch: The reset switch enables the detector to be manually commissioned and reset during testing, which causes the detector to retune the sensing loop and become ready for vehicle testing. Sensitivity boost: This function sets the highest undetected level of sensitivity and is used to prevent loss of detection of high-bed vehicles. Persistent Presence Option: This feature ensures that vehicle detection will be maintained when the vehicle is parked in the cycle for too long.
