Caemax
Wheel Telemetry Detects Brake Temperatures
Caemax has developed a new system for wireless temperature measurement on vehicle wheels. It is based on Caemax Dx telemetry and detects up to four thermocouples on one wheel.
With a sampling rate of 200 Hz, even highly dynamic temperature curves can be precisely examined during brake tests. A robust housing (IP67) protects from wind and weather. The telemetry can be quickly and securely attached to the vehicle's wheel bolts via a mounting plate. The battery allows up to 50 hours of operation with only one charge.
All measuring signals are digitized in the transmitter electronics directly on the wheel and telemetrically transmitted to the receiving unit in the vehicle interior via mirror antennas.
Up to four wheels (transmitter units) can be recorded synchronously with only one receiver. In addition, a system check with remote-controlled breakage detection is available. Additional channels such as the battery voltage and the internal housing temperature make it easier to constantly monitor the transmitters.
In addition to wheel telemetry for temperature measurement with type J or K thermocouples, Caemax offers further variants for acceleration measurement (IEPE sensors) and strain measurement (strain gauge bridges).
Via analog outputs and a digital CAN interface, telemetry can be integrated into existing measurement technology easily and quickly . This is particularly convenient with the imc measuring systems, which, in addition to telemetric data, can record, calculate and store all other sensor signals as well as field and vehicle buses synchronously in real time. At the same time, they offer a wide range of networking options for transferring measurement data directly to a cloud, for example.
