Trolex completed a two-year development program on the Trolex Sentro 8, resulting in a new concept in environmental and gas detection.

The integrated multipurpose sensing station is ready to be configured to meet gas detection and condition monitoring requirements without the need for complex investment in system design or the need for specialist backup.

Features of the system include interchangeable sensing modules.

The device can accommodate up to eight pre-calibrated sensing modules.

Acting as “plug-and-play” elements, the sensing modules are designed to continuously display the data they retrieve, store the full service history, such as data logging, calibration, failure modes and alarm settings and they run self-diagnostic checks.

At the Thoresby colliery, the environmental or eModules used are for detecting CH4, O2 and CO in two ranges from 0-50 parts per million and 0-500ppm.

The mine will also utilise remote or rModules with an output of 0.4 to 2 volts for remote sensors.

The Trolex Sentrum system is also being installed at the Thoresby colliery for the accurate monitoring of methane.

It will also be used for methane drainage pipe monitoring to measure the methane purity.

This methane is then used in power turbines for the mine’s consumption or providing energy for export to the grid.

The Trolex Sentrum system uses algorithms to correct the effects of non-methane hydrocarbon cross-sensitivity, together with mass flow calculations.

It also features infrared detection to measure the methane content from the sample on a continuous basis.
