The direction indicator is housed in a circular moulded bakelite case and a dual positionable flange allows for it to be flush panel or wall-mounted. This case is similar to the speed indicator case . The scale Presents a full circle marked off in 5° intervals and numbered every 30°. The four main cardinal points are shown, ie N.S.E.W. The IM120A the case contains a magslip receiver which is powered by 50 volts AC and accepts signals from the transmit magslip in the form of a synchronous link. Therefore, this receiver magslip follows the movement of the transmit magslip in...

Built to a British meteorological office specification, the speed indicator is housed in circular moulded bakelite case and a dual positionable flange allows for it to be flush panel or wall-mounting. These dial indicators may be remotely sited, with up to six units incorporated in a circuit. Wind speeds can, therefore, be displayed at key vantage points suck as in the crane cab for the benefit of the operator, at the base of the crane for information before operation and in the office of the safety representative. The dial is scaled over 270° and can be calibrated in MPH, KNOTS,...

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.
