Braking temperature

Brake disc temperature acquisition

Dx-Receiver Unit (RCI) – universal application

The Dx-telemetry system can be implemented universally. With one receiver unit (Dx-RCI), data from up to four transmitter units (Dx-SCT) can be received synchronously. Each Dx-SCT sends the data from one or more different sensors to the Dx-RCI. It is therefore easy to cascade an existing system: Simply connect the new sensor to a Dx-SCT transmitter and display the data in real time with the existing Dx-RCI receiver. Even if the sensors change, the associated Dx-telemetry system remains the same.

Dx-BrakeTemp for measuring temperatures on the brake disc

High precision

The CAEMAX Dx-BrakeTemp is a high-precision tool for measuring temperatures on the wheels of road vehicles. All measurement signals, such as the temperatures at the brake disc, are digitized directly at the wheels and transmitted telemetrically via mirror antennas to the receiver unit inside the vehicle. With its robust design, the system is also well-suited for harsh environments and road driving.

Measure all four wheels synchronously

All four wheels on a road vehicle can be acquired synchronously. The data are displayed in real time, as physical variables.

Short set-up time

CAEMAX supplies the sensor in special housings that are robust and easy to handle: Optionally CAEMAX offers Peiseler plates with collets for mounting. This makes the set-up time very short.
