Hydratect 2462 System Delta-Mobrey


The Hydratect electronic water and steam detection system is designed as an electronic alternative to conventional water level switches for steam raising plant. It can be used in a wide variety of situations wherever the detection of water or steam is vital for safe and efficient plant operation.

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.

Features:

  • Detect the unwanted presence of water or steam in lines, columns, and condensate pots
  • Commonly used on steam drums, drain pots, or for steam Turbine Water Induction Protection (TWIP)
  • For use as part of an ASME TDP-1-2013 compliant system
  • Electrodes for use up to 1040 °F (560 °C) and 4350 PSI (300 bar)
  • Patented design, phase detection and triple redundancy for ultimate reliability.
  • Relay outputs in varying options, for status and fault alarms
  • Fail safe design, Hydratect cannot fail in an unsafe condition
  • Configurable steam/water thresholds to adjust for water purity
  • Manifolds available to order. Refer to the manifold design sheet and liaise with sales office
