This new valve-stem mounted tire pressure sensor allows fleets to receive digital tire pressure and temperature data using Doran’s handheld SmartLink tool. With this new feature, the handheld tool can be used to transmit a low-frequency signal that will activate the tire pressure sensor and transmit the current data back to it for viewing. This enhancement provides a simple, fast and accurate method to obtain tire pressure and temperature readings during tire checks without having to climb into the cab of the vehicle to view the pressures on the monitor.
