Mobrey Hydratect 2462 Water Detection or Turbine Protection
The Hydratect Electronic Water Detection System is designed as an alternative to conventional water level switches on 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 operation. Designed to use the same water or steam detection system as Hydrastep, Hydratect provides much higher levels of reliability than conventional devices, and can be used in conjunction with Hydrastep level detection for ultimate protection. Hydratect provides local indication and configurable alarm/trip outputs.
Hydratect can be used in a wide variety of situations where the detection of water or steam is of vital importance for the safety of plant and personnel.
