Void Monitoring
YelTech has joint development of the YELV-400 with Broadsens. The YEL-V-series wireless vibration & temperature sensors continuously monitor vibration & temperature in real-time 24/7. Data is fed back to the operator via YelCloud highlighting any track movement, voids, in order to prevent failures.
The sensors have many applications across a wide range of industries, but are particularly accurate for void monitoring on railways.
Easy Application – Edge Gateways
Void monitoring on high-speed lines or switches and sections are equally important and YelTech have a solution for both. On straight sections the sensor can easily be placed using a powerful magnet, and on points YelTech have a specifically designed void monitoring clamp. Installation is easy and sensors are very reliable.
Edge-computing gateways YEL-G200S and YEL-G300 support Yeltech’s ultra-low power wireless vibration/temperature sensors. The gateway integrates 1.5GHz ARM Cortex quad-core processor with advanced data analysis ability. Vibration data can be visualised through a web browser in real time for quick time domain vibration analysis. Yeltech’s wireless gateways not only integrate vibration analysis function and void detection trend analysis, but also have up to 128 GB large data storage. The gateways can divide the ultra-low power wireless vibration sensors into multiple groups to monitor different zones/areas.

Innovative Monitoring
If there is a vibration event that exceeds 0.1g at any one of the x, y, z axes for more than 0.33s, then the sensors switch to 6.4kHz high-speed sampling rate, take a fixed number of samples and compute the vibration velocity RMS (mm/s or inch/s) and acceleration RMS (g), measures temperature and then transmit the result to the wireless gateway. If there is no vibration event detected, the sensor still toggles to high-speed mode.
