Vehicle Detectors

Vehicle detectors sense the presence of vehicles. They provide an output signal to a control unit, such as a gate or door operator, to open or close. When used as a safety device, vehicle detectors prevent a gate or door from closing on a vehicle.

EMX offers four types of sensing technologies:

Inductive – measures a change in inductance (loop frequency) caused by a vehicle passing over a buried loop
Magnetoresistive – measures a change in the Earth’s magnetic field caused by a vehicle passing in close proximity to the sensor
Ultrasonic – measures sound waves that echo off a vehicle
Motion – senses a disturbance in the Earth’s magnetic field when a vehicle passes within range
