Trolex Sentro 8 Gas Detection Station FAQs
Common questions about the Trolex Sentro 8, including multi-gas monitoring, eModules, remote sensors, alarms, MODBUS connectivity, applications and ongoing gas detection support.
What is the Trolex Sentro 8 Gas Detection Station?
The Trolex Sentro 8 is a fixed multi-gas monitoring station designed for continuous detection of toxic, flammable and environmental gases. It can monitor multiple gases simultaneously, making it suitable for demanding industrial and hazardous environments.
How many gases can the Trolex Sentro 8 monitor?
The Sentro 8 can accommodate up to eight gas eModules and/or remote sensor inputs. This allows a single station to monitor several gas hazards at the same time rather than requiring a separate monitoring station for every gas.
Which gases can the Sentro 8 detect?
Depending on the eModules and sensors installed, the Sentro 8 can monitor gases including oxygen (O2), carbon monoxide (CO), carbon dioxide (CO2), methane (CH4), hydrogen sulphide (H2S>), sulphur dioxide (SO2), nitrogen dioxide (NO2) and ammonia (NH3), with additional options available depending on the application.
What are Sentro eModules?
Sentro eModules are intelligent plug-and-play sensing modules used by the Sentro system. They are designed to be hot-swappable for straightforward replacement and maintenance, helping reduce disruption to gas monitoring operations.
Where is the Trolex Sentro 8 typically used?
The Sentro 8 is designed for demanding fixed gas detection applications including mining, tunnelling, manufacturing, power generation and other industrial environments where several gas hazards may need to be monitored continuously.
Does the Sentro 8 have visual and audible alarms?
Yes. The Sentro 8 includes integrated visual and audible alarm functions to provide clear local warning when configured gas levels or alarm conditions are reached. It also includes a backlit LCD for system information, setup and alarm configuration.
Can remote gas sensors be connected to the Sentro 8?
Yes. The Sentro 8 can operate with local gas eModules and remote sensor inputs, allowing gas monitoring points to be positioned where they are required while being managed through a central detection station.
Does the Trolex Sentro 8 support MODBUS?
Yes. The Sentro 8 supports RS-485 MODBUS communications, allowing it to be integrated into compatible monitoring, control and automation systems. MTI can advise on incorporating it into a wider Trolex fixed gas detection system.
Is the Sentro 8 suitable for hazardous areas?
The Sentro 8 is designed for demanding industrial applications and is available with certifications including ATEX, IECEx, EAC and MASC, with Group I and Group II applications supported. The correct specification should always be selected for the hazardous-area classification and installation requirements of the individual site.
Can MTI supply and support a Sentro 8 gas detection system?
Yes. MTI supplies Trolex fixed gas detection equipment and can provide assistance with detector selection, system configuration, installation requirements and ongoing maintenance. See our fixed gas detection service and support or contact MTI to discuss your requirements.
