Heavy duty float level switch - SOBA HR HY

Description

The SOBA 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. As the liquid level reaches the float, the mechanical switch inside will tilt, thus closing or opening a circuit connected to an electrical panel. The SOBA HR HY is equipped with an external adjustable resin ballast, and its +/-25º switching angle ensures a precise level measurement

Advantages

  • Double waterproof thanks to its HR HY (High Resistance) housing
  • No maintenance needed, thanks to its biconical shape that avoids any clogging
  • Easy to install, easy to use
  • Ecological float switch (no mercury, no lead)

Applications

 

  • Aggressive liquids : acids, solvents, corrosive liquids, hydrocarbons, sea water, etc...
  • Level control of multiple pumps
  • Emptying / Filling function
  • Overflow or dry-running protection
  • High / low level alarm
