Trolex TX6355 Sentro Wireless

Trolex TX6355 is engineered as a wireless gas detection platform for hazardous and harsh environments where cable installation is difficult, expensive or disruptive. As a truly wireless, fixed-point detector, it avoids the need for long cable runs, junction boxes and control cabling, significantly simplifying project design and installation.

This architecture enables gas detection coverage to be deployed precisely where it is required, including confined or hard-to-reach areas where traditional cabling is impractical. Operating as a standalone unit, TX6355 is particularly effective for post-incident monitoring, temporary worksites and rapidly changing layouts. Industrial plants, mines and tunnels can extend or reconfigure their gas detection footprint without interrupting operations or waiting for new cable infrastructure.

TX6355 continuously monitors both flammable (combustible) and toxic gases in real time, supporting compliance with stringent safety requirements in hazardous areas. It is capable of monitoring gases such as carbon monoxide (CO), hydrogen sulphide (H2S), methane (CH4) and other specified gases, giving safety teams the flexibility to address multiple risk profiles with a single detector platform.

The fixed sensor arrangement focuses on stable, continuous gas detection within defined areas, providing reliable measurement data to central monitoring systems. Early, accurate warning of gas hazards helps protect personnel, supports timely incident response and reduces the likelihood of unplanned downtime.

TX6355 uses exclusive pre-calibrated plug-in gas sensing modules (e‑Modules) to streamline installation and field servicing. These sensing modules arrive pre-calibrated, reducing on-site calibration time and simplifying commissioning. Replacement is carried out by swapping the module, avoiding complex procedures and helping to maintain measurement integrity.

This interchangeable sensor approach supports platform standardisation across multiple gas types, reducing spares inventory and training requirements. User-serviceable design at sensor module and battery level further decreases reliance on specialist support, making it easier to maintain large detector fleets in line with professional calibration and certification regimes. When deployed across multiple monitoring points, TX6355 supports centralised fleet management, enabling coordinated servicing and performance tracking.

Long-life battery operation, typically around 40–45 days between replacements, allows extended field use with fewer site visits. TX6355 is powered by commercially available, easily replaceable batteries, avoiding dependence on proprietary power supplies and simplifying logistics, particularly for remote or underground locations.

By combining cable-free installation with extended battery life, the detector helps reduce total cost of ownership. Fewer maintenance interventions, no cable repairs and reduced call-outs contribute to measurable lifecycle savings, especially where access windows are limited and labour costs are high.

TX6355 is housed in a heavy-duty enclosure that withstands rough handling and demanding environments such as mining and tunnelling. With an enclosure rated to at least IP65, it resists dust ingress and water jets, supporting reliable operation in dirty, wet or exposed areas.

EMC-compliant design helps maintain stable performance in electrically noisy industrial settings. Multiple third-party certifications for hazardous areas and performance reinforce suitability for regulated applications where compliance is critical.

For operators working underground or in low-light conditions, TX6355 incorporates an integral LCD display with backlight for clear visibility of status information and gas readings. Visual LED alarm indicators highlight both general and high alarm states at a glance, supporting rapid local decision-making.

For networked monitoring, TX6355 can be powered and communicate via the Strata CommTrac wireless mesh network, described as highly reliable in demanding industrial environments. It can also utilise existing Wi‑Fi infrastructure, easing integration into legacy or modern wireless networks and limiting the need for additional communication hardware.

The detector provides strata-specific digital wireless output signals for connection to site monitoring and control systems, ensuring that real-time data reaches control rooms for incident response and reporting. TX6355 can monitor external relay contacts and communicate their state via the wireless network, as well as drive external relays to control equipment such as fans or pumps.

This capability enables automatic control actions in response to gas alarms, including starting ventilation systems or other mitigation measures. Integration with auxiliary audio-visual alarms via analogue or relay outputs (where fitted) further enhances site-wide awareness and supports consistent, automated safety responses.

TX6355 forms part of the Trolex SENTRO gas detection product family, allowing it to slot into broader system architectures and multi-point monitoring strategies. Its capability to support both toxic and flammable gas safety requirements in fixed installations enables a single detector platform to cover diverse applications across a site.

Backed by detailed data sheets and user manuals, TX6355 provides engineering teams with the information needed for confident design and commissioning. As operations expand or site layouts evolve, the wireless architecture and modular sensing approach allow systems to scale, helping maintain safety performance while controlling project and maintenance costs.
