Vector W200P Wind Vane
The W200P Potentiometer Windvane incorporates a precision wire-wound potentiometer as a shaft angle transducer, enabling wind direction sensed by the F20 fin to be accurately determined when connected to suitable measuring equipment, such as a data logger or PLC.
The potentiometer has the lowest possible torque consistent with long life and reliability, the small gap at north being filled with an insulating material to ensure smooth operation over the full 360°. The standard F20 vane-arm (fin) assembly is attached using the unique Porton™ gravity fastener allowing good alignment and rapid attachment and release. A large alternative vane-arm (fin), type F20/LV is available where improved sensitivity is required.
Construction is from anodised aluminium alloys and stainless steels for exposed parts. Combined with a hard plastic (upper) bearing and precision ball-races, the result is an instrument suitable for continuous exposure to the weather, with a long service interval. This windvane is Fixed Reference, that is to say that it must be aligned with north during installation and fixed in that position/orientation during operation.
