Features 1、The Vehicle Loop Detector is mainly used to detect the existence and passing of vehicles 2、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 3、Selectable Pulse Time: This feature sets the length of time that the pulse relay will be energized for 1 Second or 0.5 Seconds 4、Pulse Relay Selection: The Pulse Relay may be configured to energize on detection of a vehicle or when the vehicle leaves the loop 5、Permanent Presence Option : This feature ensure detection of the vehicle will be maintained when the vehicle is parked over the loop for extended periods Specification Features: The Vehicle Loop Detector is mainly used to detect the existence and passing of vehicles 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 Selectable Pulse Time: This feature sets the length of time that the pulse relay will be energized for 1 Second or 0.5 Seconds Pulse Relay Selection: The Pulse Relay may be configured to energize on detection of a vehicle or when the vehicle leaves the loop Sensitivity Boost : This feature sets the undetected level to maximum sensitivity and is used to prevent loss of detection of high-bed vehicles Switch Selectable Sensibility: 4 sensitivity setting are available on the switches to allow flexibility in configuration Switch Selectable Frequency: 4 frequency settings are available to prevent cross-talk between adjacent loops Filter Option: This option is used to provide a delay between detection of the vehicle and switching of the output relay . This relay is normally used to prevent false detection of small or fast moving objects Specifications: Supply voltage 220VAC Power 4.5VA Output relays 240V/5A Operating temperature -20~65°C Storage temperature -40~85°C Frequency range 20 kHz to 170 kHz Temperature compensation 50°C/ h Reaction time 10ms Signal holding time Unlimited/limited Sensitivity Higher:0.02% high:0.05% low:0.1% lower:0.5% Loop inductance Total loop plus connection wiring: 50μH to 1000μH.
