HRH-7 | Level switch

  • Suitable to operate/work in harsh conditions due to the high degree of protection IP65
  • The switch monitors the level changes in wells, reservoirs, tanks, 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)
  • Choice of function PUMP-UP or PUMP-DOWN
  • Adjustable time delay of output (0.5 - 10s)
  • Adjustable sensitivity using a potentiometer 
  • 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.
  • Output contact: 1x switch / DPDT 16A / 250V AC1
