Average speed based on the signal received from the Anemometer is computed over a six-second period to be clearly displayed on this mounted unit. This is to prevent a rogue gust of wind from tripping the alarm relay. The relay is a double pole type that enables two different circuits to be activated. Responding to the pre-set level, the relay will energise visual and audible alarm circuits to warn the workforce and others that the critical wind speed has been exceeded.
Can be supplied with a Klaxxon horn upon request.
