The Mobrey Hydratect 2462 detection system (photo) is used in applications where the detection of water or steam is vital, such as boilers, steam drums and steam-line drain pots. A functional safety assessment carried out by Exida determined that the Mobrey Hydratect system meets the requirements of safety integrity level (SIL) 3. With capabilities to operate at up to 300 bars and 560°C, Hydratect is intended as a replacement for conventional float switches, and consists of a compact twin-channel electronic unit connected to a pair of electrodes. Each channel gives independent indications of the presence of water or steam that are said to be more reliable than those obtained with electro-mechanical devices. By installing the electrodes in vessels or steam lines and measuring the resistance, the presence of water can be detected, allowing appropriate safety measures to be taken. — Emerson, St. Louis, Mo.
