BulletWind Speed Sensors
Wind Speed Sensors
A range of Optoelectronic and Switching Anemometers is available with various different output signals and power requirements making them suitable for a wide range of applications, including Meteorology, Wind Assessment and Offshore, where accuracy and sensitivity are important.

Our A100 Series First Class Anemometers share a common body and 3-cup rotor design which has been shown to meet the requirements for a Class 1 Anemometer according to IEC and MEASNET specs, making them...

  the first choice  
  for high-precision  
  wind assessment applications.  

More on Wind Assessment: English... Deutsch... Espanol... Francais... Italiano... Portuguese Portuguese

A100 Series Anemometers are available with an optional MEASNET/IEC Calibration Certificate if required.

BulletWind Direction Sensors
Wind Direction Sensors
Several types of Windvane are available for use with our range of anemometers or for use alone, including Potentiometric and Self-referencing types.

The premium quality W200P windvane is a popular & durable choice for demanding Wind Assessment applications, having "First Class" performance to meet the requirements of the IEC61400-12-1 standard.

First Class W200P/FC windvanes with larger vane/fin, higher max windspeed rating, and 10K pot are now available.

W200P windvanes are now available with an optional MEASNET/IEC Calibration Certificate if required.

.Pro Bundles with MEASNET Calibrations
For Wind Assessment applications, we recommend our "Pro Bundles" (Professional Installer Kits)

"Pro Bundles" usually available from stock include:
A100LK Pulse/Frequency Output Anemometer
PC3 antisurge option
R30K First Class Rotor
MEASNET Calibration Certificate
405 mount (for 1in dia pole)
6M (19 ft 8 ins) Cable + CJK1 Cable Joint Kit.
A100R Contact-Closure/Reed-Switch Anemometer
R30K First Class Rotor
MEASNET Calibration Certificate
405 mount (for 1in dia pole)
6M (19 ft 8 ins) Cable + CJK1 Cable Joint Kit.

. Low Maintenance, Long Life
Due to our use of high-quality parts and manufacturing processes, our "Vector Instruments" brand A100 Series Anemometers and W200P Series Windvanes can operate for long periods, without needing any servicing or maintenance, while continuing to provide measurement accuracy exceeding that of competing "no moving parts" sensors.

. Repair, Maintenance, Re-cal
For instruments that have already given years of service in the field, or instruments which have become damaged, we offer a Maintenance/Repair/Refurbishment service for the instruments we manufacture, along with (re)calibration services for our anemometers & windvanes. Please enquire.

Our factory aims to achieve a repaired/refurbished anemometer/windvane which performs "as new". Anemometers are completely stripped-down, electronics tested/adjusted as necessary, re-used parts are cleaned, then the anemometer is rebuilt using a brand-new bearings/spindle set and cable. Rotors are completely rebuilt with new cups and locking mechanism. Similar procedures are applied to windvanes. Having access to all original parts and test equipment means that the results of our Factory repair/refurbishment work is superior to the "field repairs" that others may offer.

Using our Factory Repair/Refurbishment services ensures that the value of your investment in "Vector Instruments" sensors is maximized by way of continued high-performance and accuracy over many years, and over many measurement campaigns/deployments at different sites.

.Dataloggers, Weather Stations
Many dataloggers, including Campbell Scientific loggers, NRG loggers (Symphonie) and Secondwind loggers (Nomad 2), are compatible with our wind/weather instruments and together form very capable Automatic Weather Stations (AWS) suitable for many applications, including wind assessment.
BulletAir Temperature Sensors
Air Temperature Sensors
We also manufacture a miniature solar radiation shield, type T351, and a selection of compatible probes for air temperature measurement. Also available is the T302 UK Met Office pattern precision aspirated air temperature sensor.

The T351-HMP110 version of our T351 miniature shield/screen is now available - This model is fitted with a high quality HMP110 Relative Humidity & Temperature sensor and provides voltage output signals for RH and Temperature suitable for connection to most dataloggers.

.Porton Anemometer and Windvane
These weather instruments, initially designed at the Chemical Defence Establishment at Porton Down in the UK during the 1960s, have been manufactured and improved by Vector Instruments since 1972 with a range of instruments for different purposes being available today.
BulletRelative Humidity Sensors
Several sensors for measuring the Relative Humidity of the air are available, including our T351-HMP110 voltage output RH&T sensor with screen/shield.
.4-20mA, Baro, Rain, other...
4-20mA, Baro, Rain, other...A range of Wind Indicators/alarms, 4-20mA converters, Barometers (Atmostpheric Pressure Sensors), Rain Gauges (Pluviometers), Surface-Wetness/Frost and Other Weather Sensors are also available.
./HE-4 Anti Icing Heater Option
Our Anemometers and Windvanes can now be fitted with the new /HE-4 internal anti-icing heater option to help alleviate problems due to icing conditions. Because the /HE-4 heater is fitted inside the instrument, anti-icing effectiveness is improved, NO extra cables are required, and there is NO change to the instrument shape, dimensions or appearance meaning that optimum performance and accuracy is maintained.

Red Ball BulletVector Instruments
Vector Instruments (V.I.) specialise in the manufacture and sale of quality, robust, professional wind speed and wind direction measuring equipment together with other weather sensors and associated equipment. Our products are available for sale to Trade, Business, Government and Educational customers (B2B sales).

Vector Instruments is a trading name of Windspeed Ltd. Vector Instruments have been developing and producing anemometers and windvanes in North wales, UK since 1972 and was only recently reorganised into a limited company, Windspeed Limited and continues to produce instruments under the Vector Instruments brand/trade name.

Recognised for many years as a leading name in the field of wind instrumentation for scientific research, Vector Instruments sensors have steadily found new uses in environmental monitoring, alternative energy, utility, and industrial applications. For this wider market, the range of wind sensors has been extended to include several new versions featuring different transducer types, outputs and other features optimised for specific applications. V.I. policy is one of continuous improvement of the whole product range, with periodic updating of specifications, while maintaining compatibility with superseded products wherever possible. New sensor designs undergo a thorough program of laboratory tests and field trials before release.

Besides the established range of wind speed and wind direction instruments, V.I. have for many years produced specialist temperature sensors; these include the T351 naturally ventilated mini-screen in versions accepting several types of sensing element, an aspirated temperature sensor (T302) made to a UK Met Office design, and the H301 wet and dry bulb psychrometer.
