CARSENSE 303 VEHICLE DETECTOR IS “POSITIVELY MAGNETIC”
Magnetoresistive Sensing Technology Takes EMX Detector to a Higher Level of Performance
The first magnetoresistive effect was observed by Lord Kelvin back in 1851. During his experiments with pieces of iron he discovered that the resistance increases when the current is in the same direction as the magnetic force and decreases when the current is at 90 degrees to the magnetic force.
Today, this force is being increasingly used in sensing technology for applications in the security, gate, door operator and parking industries. EMX Industries Inc., a key worldwide partner to the aforementioned industries is at the forefront of automated vehicle detection. The CarSense 303 (CS303) by EMX features advanced 3-axis magnetoresistive sensing technology that measures the Earth’s magnetic field and reacts to disturbances caused by ferrous objects, such as cars, vans and trucks.
The CS303 carries new Detect-On-Stop (DOS) feature which only reacts to the vehicle when it has come to a complete stop on the sensor, as opposed to a vehicle just passing by on its way to somewhere else. According to a press release from EMX, this “is a worldwide unique feature to EMX detectors.” This device is particularly useful in tight spaces, like cramped car parks, where over sensitive detectors lead to subpar boom gate performance (as the gate may raise in reaction to passing cars). The sensing technology is field proven and is also used in automatic car washes.
