Wind Monitor from R.M. Young
Distributor for R.M. Young in SwedenThe Wind Monitor measures wind speed with a propeller and wind direction with a vane in the same sensor. It was developed for ocean weather buoys and now comes in versions for weather stations, ships, mountain tops and air quality monitoring. We help you choose a model, wire the sensor and service it.
The models
The same basic design in several versions. All mount on a pipe with an outside diameter of 34 mm.
Standard
Wind Monitor 05103
The standard model for weather stations and masts.
- 0–100 m/s, ±0.3 m/s or 1%.
- Available with 0–5 V (05103V) or 4–20 mA (05103L).
Marine
Marine Wind Monitor 05106
For ships, buoys and coasts.
- Corrosion-resistant ceramic bearings.
- Watertight cable connection with 3, 8 or 12 m of cable.
Long life
Heavy Duty Wind Monitor-HD 05108
For sites where the sensor has to run a long time between service visits.
- Oversized ceramic bearings.
- A higher-pitch propeller that turns more slowly at the same wind speed.
Mountains and ice
Heavy Duty Wind Monitor-HD-Alpine 05108-45
The HD model in black, for high sites exposed to icing.
- Ice-resistant coating on all external surfaces.
- The black surface warms in sunlight.
Air quality
AQ Wind Monitor 05305
A sensitive model for light winds, for example for dispersion calculations.
- The propeller starts at 0.4 m/s.
- 0–50 m/s, ±0.2 m/s or 1%.
Serial output
Serial Output Wind Monitor 09101
With an optical encoder and digital output.
- RS-485 with NMEA among its protocols.
- Wind direction ±2° over the full circle.

Signals and wiring
In its basic form the Wind Monitor gives an AC voltage whose frequency follows the wind speed, and a potentiometer signal for wind direction. A Campbell Scientific data logger measures both directly.
The 05103 is also available with a 0–5 V voltage output and with a 4–20 mA current output. The current output is recommended where there is electrical noise and when the cable is around 300 metres or longer. For the 05106 and 05108 the corresponding signal converters are separate units.
The Serial Output Wind Monitor has an optical encoder instead of a potentiometer and sends data serially over RS-485.
- 05103VVoltage output, 0–5 V.
- 05103LCurrent output, 4–20 mA.
- 09101Serial output, RS-485.
- 09106Marine version with serial output, preset for NMEA.
- 05305V and 05305LThe AQ model with voltage or current output.
Suited to
Weather stations and masts
A proven sensor for wind speed and direction that is easy to check and service.
Harbours and ships
The Marine Wind Monitor withstands salt and moisture, and is available with serial output for NMEA.
Mountains and exposed sites
The HD models have heavier bearings and shaft, and the Alpine version an ice-resistant coating.
Air quality
The AQ model measures light winds accurately, which dispersion calculations need.
What we do

Wiring
The instrument is connected to a Campbell Scientific data logger or directly to your system.
Installation
Mounting, alignment and commissioning on site, on a mast, roof or quay.
Service
Checks, spare parts and replacement of wearing parts, with a short path to the person who built the station.
Frequently asked questions about the Wind Monitor
Which Wind Monitor should we choose?
The standard 05103 suits most weather stations. By the sea we choose the 05106, where service visits are far apart the 05108, at sites exposed to icing the 05108-45 and for light winds the 05305.
Does the Wind Monitor cope with icing?
The Wind Monitor-HD-Alpine 05108-45 has an ice-resistant coating and a black surface that warms in sunlight. The sensor has no electrical heating, so in severe icing a heated ultrasonic anemometer may be a better choice.
Is there a Wind Monitor for hazardous areas?
The Wind Monitor-IS 05501LM is tested to the American standard UL 913 for Class I, Division 1. If you need ATEX certification we suggest the WindObserver IS from Gill Instruments instead.
Can you service our Wind Monitor?
Yes. We check the sensor, replace bearings and propeller and source spare parts.
How is the sensor connected to the logger?
In its basic form, directly to a Campbell Scientific data logger. For control systems we usually choose the 4–20 mA current output or the serial output.
