HRH-1:Level switch

  • serves for level monitoring in wells, tanks, pools, reservoirs....
  • options:

- single switch with single-state monitoring
- single switch with double-state monitoring
- 2 independent switches with single-state switching

  • one-state monitors one liquid level ( full or empty), two-state monitors two levels (switches at one level and switches off at another)
  • selectable by DIP switch:

- drain in
- drain away
- combination

  • adjustable time delay when activated by level change, type selectable by DIP switch
  • sensitivity adjustable by potentiometer
  • frequency 50 Hz prevents liquid polarization and increased oxidation of measuring probes
  • supply AC 230 V, AC/DC 24 V or AC 110 V galvanically separated
  • output contact: 2x changeover 16 A /250 V AC1
