Details :

  • Highly reproducible
  • Insensitive to dirt
  • DIN flange housing
  • Precise setting of the switching valve by means of a 180o scale / setting diagram

Characteristics : Mechanical flow switch, for fluid media, with no-contact triggering of an adjustable Reed contact. Robust construction in stainless steel material.

Handling and operation :

  • Include straight calming section of 5 x DN in inlet and outlet
  • When tightening the union nut, the connection piece must be countered using an open-ended spanner (SW 19).
  • If the media are dirty, install a filter (use magnetic filter for ferritic components).
  • It must be ensured that the values given for voltage, current, and power are not exceeded.
  • When switched on, a load must be connected in series.
  • The electrical details apply to ohmic loads. Capacitive and inductive loads must be operated using a protective circuit.

Options :

  • Signal lamp
  • Temperature display 0..120 oC
  • Temperature monitoring 40..90oC
  • Temperature resistant up to 150 oC
  • Protection class IP 65
  • Metal cap
  • Germanischer Lloyd (Type VR)
  • Switching ranges for oil or gas
  • Special values
  • Selected hysteresis
  • Rhodium contact (250 VAC, 0,5 A, 30 VA)

Ordering information :

  • Specify direction of flow, medium, and switching range.
  • For oils, state viscosity, temperature and designation (e.g. ISO VG 68) (enquire about range).
  • For gases, state pressure (relative or absolute), temperature and medium (e.g. air) (enquire about range).
