Trailer Tire Pressure-Monitoring System
A tire pressure-monitoring system for use with a trailer. The monitoring system includes an inductive proximity sensor mounted adjacent each wheel. To activate the sensors, a target is mounted on each brake drum. Rotational speed data for each wheel is relayed from each sensor to a programmable logic controller which compares the rotational speed of a wheel with another wheel. Sensitivity parameters written into the program contained in the programmable logic controller compares the input data and, if the data falls outside the safe parameters, alerts the driver by activating and audio or visual alarm mounted within the tow vehicle. The sensitivity of the programmed logic may be optimized to differentiate changes in a tire diameter due to turning versus an actual loss in tire pressure.
