A Vehicle Speed Limiter/Governor is a small, electronic device that restricts the top speed of a vehicle to 73 miles per hour.The device can be installed on most vehicle models manufactured after 1990, which allows you to control your teen's speed whether he or she drives a new or used car. Speed Limiter device is designed to limit the speed of vehicle like truck, school bus, car and so on. Nowadays, we are manufacturing and developing the devices . Speed Limiter will monitor the road speed of the vehicle by the installation of an electro-mechanical speed sensor. When the pre-defined speed is reached, the speed limiter will temporarily cause the engine to lose the power. The engine power will be reinstated at a speed not less than the pre-warning switch point, which is 5% below the set speed (without affecting the other performance parameters of the vehicle in any manner). Capable to limit the speed of the vehicle at the set speed as stipulated by the authority. Maximum tamper proof and fail safe against disconnection and failure of various components like power supply, speed sensors, mechanical actuator system, linkages etc. It Will not interfere with the brake systems of the vehicle.
