TCB2-G Fixed Gas Leak Detector

TCB2-G Fixed Gas Leak Detector

Monitor gas concentration inside a pipeline or piece of equipment with a flange-mounted detector.

  • Place the sensing point inside the process

    The listed flange connection and high-temperature sensor option address an in-line measurement location.

  • Make the alarm available locally

    Configurable setpoints and integrated audible/visual indication support a response near the installation.

  • Connect the process system

    The listed switch and signal output options support PLC or DCS monitoring; modular sensors simplify service planning.

Confirm gas, process temperature, flange size, sensor configuration and output wiring.
