Description

The Instromet wind wind speed and direction switch is designed for activating or de-activating peripheral equipment.

This unit comes complete in an IP rated enclosure and can be powered from 240v AC.

Wind speed activation range is 0-90mph and the wind direction activation is via the eight main compass points.
Further controls are “on” timer, to prevent activation caused by short sharp gusts and an “off” timer to ensure the wind parameters have fallen sufficiently before de-activation of the switch.

The Wind switch incorporates a relay which can be used in either the normally open or normally closed configuration to switch a load of up to 5A. Any loads greater than this should be switched via an electrical contractor.

Two variations of wind sensor are available, “Basic” and “Pro”.
The “Basic” version incorporates two sintered bronze bearings in its cup assembly and the “Pro” version uses a ball bearing at its base and is ideal for harsher environments, such as coastal areas.

Precision Engineering and Quality

The Instromet 353-0004-001 is manufactured from anodized aluminum alloy, UPVC, stainless steel, and molded polypropylene cups, the units are lightweight yet very robust.  Wind Direction is sensed by a precision conductive potentiometer which combines exceptionally long life with high sensitivity.  Wind speed is derived from a “Hall Effect” solid state sensor coupled with a cup rotor held in place with precision stainless steel ball race and ‘Oilite’ bearings for very high sensitivity and very long life.
