Volumatic SensorThe volumatic sensor is a unique device developed to detect a forced entry into the air space of motor cars, station wagons and panel vans. The unit can be located anywhere in the confined air space of the vehicle. It is connected to an alarm system and once activated will trigger the alarm. The advantage of using the volumatic sensor in the comparison to ultrasonic or microwave is that it gives equal cover to every corner of the vehicle where as ultrasonic is limited in the distance it will travel from it's transducer which is usually located at the front dashboard area. The volumatic sensor is not as sensitive to wind like ultrasonic or electromagnetic fiend of a microwave/radar sensor. The volumatic sensor will detect impact into the glass area such as breaking a window, impact into the door locks or sunroof. The sensor measures inside to outside air pressure several times per second. In the case when a window is smashed the pressure in the cabin area is dramatically increased causing the sensor to trip. |
