Hydratect 2462 System

Hydratect 2462 System
Conductivity Probe Steam and Water Detection

An electronic alternative to conventional water level switches for steam raising plants. Hydratect can be used in a wide variety of situations wherever the detection of water or steam is vital for the safe and efficient operation of a plant. The Hydratect 2462 control unit provides signal processing for two electrodes. Each channel monitors the status of its associated electrode. Four conductors are used between the control unit and each electrode so it can differentiate between steam, water, short-circuit and open-circuit. A green LED indicates water, a red LED indicates steam, and an amber LED indicates a fault condition. Each channel has a status relay to indicate water or steam, and a fault relay which will de-energise on a fault condition. The two channels are completely independent having separate power supplies, signal processing and fault detection. The relay outputs can be externally wired for a ‘one out of two’ or ‘two out of two’ tripping scheme.  A Hydratect 2462 system consists of electrodes which are fitted into inserts which are welded into the pipe work. Alternatively, manifolds can be supplied to drawing with inserts already in place. Electrodes are protected by covers. A military specification high temperature cable connects each electrode to the Hydratect control unit.

A typical application to ensure TWIP (Turbine Water Induction Protection) is condensate level detection in drain pots (condensate pots).

Hydratect can be used to give compliance with ASME TDP-1, Prevention of Water Damage to Steam Turbines Used for Electric Power Generation: Fossil-Fuelled Plants.

Features & Benefits

 

  • Detect the unwanted presence of water or steam in lines, columns, and condensate pots
