Yeltech’s Rail Temperature Monitoring Unit is an automatic temperature warning system which allows you to monitor the track temperature remotely, without having to go track-side.
During periods of high temperatures, the rail can reach up to 20°C above air temperature when in direct sunlight. When exposed to these temperatures, the rail expands and is subject to strong compression.
This causes major performance and safety issues for rail operators, as the risk of derailment increases.
The RTMU is ideal for monitoring temporary critical sites as it is portable, with newly developed features for an easier installation. This largely reduces the need for track-side monitoring and lookouts, saving costs and reducing safety risks.
The RTMU is installed at the web of the rail and is immediately secured with the high strength magnet. When the device makes contact with the surface, the activation sensor is triggered turning the device ON.
When the device is removed from surface the same sensor is triggered to turn the device OFF. The RTMU is programmed to transmit the data on specific instructions with an internal threshold of 25°C. The device will feature predetermined transmission rates. Normal rate is when the RTMU wakes up and sees the tempbelow 25 °C, it will store the data and then send the bulk of readings/data every 12 hours.
Fast rate of the RTMU is when the temperature exceeds the threshold of 25 °C and the CRT alarm thresholds that have been set. When the RTMU wakes up, if the temp is above 25 °C, then it will keep transmitting data to the server every 30/60 minutes. All data is accessible through the Yeltech App if specified or through webserver allowing you to easily identify your device and the temperature measurements.
