AT 120 HR HY

Description

The AT 120 HR HY is a heavy duty float level switch designed for aggressive liquids. This float is encased in a HR HY (High Resistance) press-vulcanised housing, which ensures a double waterproof. The AT 120 HR HY can be connected directly to pumps up to 1.5 HP or through a relay if working with high power pumps. Its wide switching angle of 120º protects the pump’s engine and the electrical panels from jerking, specially when dealing with very agitated liquids.

Applications

  • Aggressive liquids : acids, solvents, corrosive liquids, hydrocarbons, sea water, etc…
  • Emptying / Filling function
  • Overflow or dry-running protection
  • High / low level alarm
