VD Flow Switch

Details :

• Highly reproducible
• Insensitive to dirt
• DIN flange housing
• Precise setting of the switching valve by means of a 180^o 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..90^oC
• 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).
