The main purpose of a rollover sensor is upon sensing a rollover it safely and effectively isolates any electrical sources of ignition, a must have in flammable goods haulage. The RS400 utilizes a solid state 3-axis accelerometer with a filtered output to avoid accidental triggering by rejecting any readings that are not indicative of a roll over, such as bumps. The device will not be activated at less than 45 degrees tilt and the mounting bracket has an integrated hinge to test this in place, ensuring that the rollover sensor has been installed correctly, before it becomes relied upon.
