Vane switch / vane relay switch RHEASREG® WFS

Mechanical wind vane switch RHEASREG® WFS wind vane switch with switching output, in an impact resistant plastic housing, with stainless-steel paddle, for flow monitoring of gaseous, non-aggressive media.

The flow sensor device is used as a flow controller or air flow monitor in air conditioning ducts, in air intake or exhaust devices of ventilators or in electric heating registers (also for contaminated, oily air).

Function

Monitor:

Contact 1 - 3 breaks when flow rate drops
to the preset value.
Simultaneously, contact 1 - 2 closes and
can be used as signal contact.
Device is factory-set to the minimum switch-off
value, which can be increased by turning the range
adjusting screw clockwise.

Installation:

vertical in horizontal air ducts.
Min. smoothing distance = 5 x duct diameter
upstream and downstream of vane. For airspeeds
> 5 m/ s, vane is to be trimmed at the marked
spots. Thereby the minimum switch-off value
increases to approx. 2.5 m/ s and the minimum
switch-on value to approx. 4 m/ s.
