Integration planned." url: https://aethair.io/sensors/trolex-gas-detectors/ --- Sensors · Gas Detectors # Trolex Sentro X Gas Detectors The Trolex Sentro X (TX6310) is a fixed gas-detection platform for mining and heavy industry. One controller takes a single hot-swappable, self-identifying gBloc sensor for CO, H₂, H₂S, NH₃, NO, NO₂, O₂, SO₂, CH₄, or CO₂, and reports live concentration plus STEL, TWA, and %LEL alarms over RS485 Modbus RTU, 4–20 mA, and 0.4–2 V.

[All articles](https://aethair.io/resources/) Questions ## Trolex Sentro X FAQ Which gases can the Sentro X detect? The Sentro X takes one hot-swappable gBloc that self-identifies its gas type and range. Approved gBlocs cover carbon monoxide (CO, to 1000 ppm), hydrogen (H₂, to 1000 ppm), hydrogen sulfide (H₂S, to 50 ppm), ammonia (NH₃, to 500 ppm), nitric oxide (NO, to 50 ppm), nitrogen dioxide (NO₂, to 100 ppm), oxygen (O₂, to 25% v/v), sulfur dioxide (SO₂, to 20 ppm), methane (CH₄, 5% v/v pellistor or 100% v/v infrared), and carbon dioxide (CO₂, 100% v/v infrared). Each reports live concentration plus STEL, TWA, and, for flammables, %LEL. How does the gBloc sensing module work? A gBloc is an intrinsically safe, pre-calibrated gas-sensing module that plugs into the Sentro X controller or a remote sensor and can be hot-swapped with the power on. Each gBloc carries its own gas type, range, serial number, and default STEL/TWA setpoints, which the controller adopts automatically on insertion. When a gBloc for a different gas is inserted, the controller detects the change and reconfigures itself without recalibration.
