For monitoring one or two levels in IP65 protection

EAN: 8595188149471 | Code: 4947


  • 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.


  • Output: 1x CO, 16 A
  • Sensitivity: 5-100 kΩ
  • Number of functions: 2
  • Housing: BOX
  • Supply voltage (frequency): 24-240 V AC/DC (AC 50/60 Hz)
  • Dimensions: 139 x 139 x 56 mm (5.5 x 5.5 x 2.2“)
