dimensional drawings.
1.2 Product recycling/disposal
Recycling of equipment and packaging should be taken into consideration and disposed of
in accordance with local and national legislation/regulations.
1.3 What the Hydratect 2462 does
The Hydratect 2462 system is the electronic alternative to conventional water level
switches on steam-raising plant. The system contains a compact, two-channel electronic
control unit connected to a pair of electrodes that are mounted in the plant pipe-work
(See
Figure 1-1 on page 2 ).
Each of the two channels gives independent indications of the presence of water or steam
that are much more reliable than those obtained with conventional electro-mechanical
devices. The electronics control unit provides a local indication of steam, water, and fault
states, and has configurable fault- and trip-outputs.
Typical applications of the Hydratect 2462 system are:

Drain pots.

Water detection in steam lines.

Low- or high-level water detection.

Wherever it is necessary to detect water or steam.
