EC 28 Fixed Transmitter

The GfG EC 28 is a fixed‑point gas transmitter that provides a continuous 4‑20 mA analog signal representing the concentration of a selected toxic or combustible gas. As a Fixed Gas Detector, it is normally installed in the protected space, on the person, or at a fixed sensor point with signals returned to the relevant alarm or monitoring system. In that role, its primary purpose is to detect hazardous gas, oxygen condition, fire indication or another safety-related condition identified by the listed category. Fixed, portable, optical, heat, gas and oil-mist sensors use different principles, so calibration and functional testing must match the actual detector type. Capacity: 1 gas per point. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.
