HRH-7 | Level switch for monitoring 1 or 2 levels in increased protection


  • Suitable to operate/work in harsh conditions due to the high degree of protection IP65.
  • Swich monitors the level changes in wells, reservoirs, tanks, tankers etc.
  • It is possible to select the following configurations:
    - One-level switch of conductive liquids monitors one level (by connecting H and D).
    - Two-level switch of conductive liquids monitors two levels (switches on at one level and switched off at another level). 
  • Adjustable time delay of output (0.5 - 10 s).
  • Adjustable sensitivity using potentiometer (5 -100).
  • Measuring frequency 10 Hz prevents liquid polarization and increased oxidation of measuring probes.
  • Measuring circuits are galvanically separated from the power source of the product and circuits of the relay contact by enhanced insulation according to EN 60664-1 for overvoltage category III.
