DATASHEET

Introduction

Wind Speed Sensor is designed with rugged components stand up to hurricane‐force wind yet is sensitive to a light

breeze. It includes sealed bearings for long life. The range and accuracy specifications have been verified in wind‐tunnel

tests. In areas where icing of the anemometer is a problem, drip rings deflect water from the joint between moving

parts.

Theory of Operation

The sensor’s cup assembly consists of three cups mounted on a cup assembly hub. A shaft, which rotates on precision‐

sealed ball bearings, connects the cup assembly to a magnet assembly. When the shaft is rotated, the turning magnet

assembly causes a reed switch to close. It closes twice for every rotation of the shaft. The pulses produced by this

closure is counted by the connected electronics.

INSTALLATION

Guidelines

The wind speed sensor comes in three different parts. We have the sensor body, the anemometer cup wheel and an

Allen key to mount the cup wheel on the sensor body. There are different ways to mount the sensor.

Tools and Materials Needed

Please make sure you have all the necessary material as mentioned below:

‐ Wire cutters and stripper

‐ Multi meter

‐ Screwdriver

‐ Electrical tapes to cover the wire

‐ Cable ties

‐ Adjustable Wrench

‐ Allen wrench (Supplied with sensor)

Location Recommendation

In order to report accurate weather information, you must take care in deciding where to place your weather station.

The process of deciding how and where to install your weather station is called "Siting". Siting is the single most

important factor in ensuring accurate readings. In fact, siting influences

the accuracy of weather readings much more than the quality of the

weather instruments themselves.

When selecting your mounting system, take into consideration that you

will occasionally need to access the anemometer for preventive

maintenance. Use the following guidelines to determine the best

location for mounting the wind speed sensor

•Allow sufficient clearance for the wind sensor.

•Install the anemometer in a location where wind flow is

unobstructed by trees and nearby buildings.

•Rule of Thumb-Near a building, mount the sensors outside the zone of influence. Horizontally this extends

roughly twice the height of the building upstream and ten times downstream. Vertically it extends to about

twice the height of the structure

If the requirement is to measure the true local conditions

•Mount the sensor so that the wind cups are at least 7 feet (2.1 m) above obstructions such as trees or buildings

that may obstruct wind flow

•Mount the sensor as the highest object for 50 feet in all directions.

Mounting

The Anemometer can be mounted using the three holes in the bottom mounting plates. This allows mounting on any flat

LEVEL surface.

Caution:

To prevent damaging the wind cups properly mount the sensor/bracket combination on the mast before fitting the wind

cup-unit whenever possible.

Note: Do not lubricate the force bearings

Orientation: The Anemometer should be mounted with its axis as close to vertical as possible to provide for the best

measurement of horizontal wind movement

Steps for Mounting:

1. With the supplied U‐bolt, the sensor suite can be mounted on a pole or rod

2. While holding the mounting base of the sensor suite against the pole, place the two ends of the U‐bolt around

the pole and through the two holes in the C‐shaped bracket on the base.

3. Gently slide the wind cup assembly down onto the anemometer’s stainless‐steel shaft

4. Use the allen wrench provided to tighten the set screw slightly on the side of the wind cups.

NOTE: DO NOT PUT EXCESS PRESSURE ON THE ALLEN WRENCH AS THIS CAN DAMAGE THE SENSOR PERMANENTLY

5. Spin the wind cups. If they do not spin freely, loosen the set screw, then retighten the set screw.

6. Repeat above step until the wind cups spin freely

7. When the sensor is properly oriented, tighten the hex nuts with a wrench.

Local Testing: Spinning the anemometer cup assembly will produce a series of pulses. To verify sensor output, monitor

this signal with either a translator module, data logger or an ohmmeter.

Caution

Do not Open the sensor bottom. This can permanently damage the sensor

and void warranty.

Guidelines for Securing Cables

•To prevent fraying or cutting of cables, secure them so they will not whip about in the wind.

•Secure cable to a metal pole using cable ties or by wrapping tape around both the cables and the pole.

•Place clips or ties every 3' – 5' (1 – 1.6 m).

Example Installations

Calibration

•If using Modbus sensor then the Wind speed Sensor is factory calibrated.

•If using analog output senor then use the following info to calibrate:

oOutput: 0 ‐ 5 VDC (0 to 250 km/hr)

oWind Speed in km/hr = 50*Sensor Output voltage (in Volt)

oOutput: 4‐20mA (0 to 250 km/hr)

oWind Speed in km/hr = 15.625*(Output in mA ‐ 4)

If the cable length is insufficient for the installation, additional cable can be added to the existing cable. If this is done, an

accuracy de‐rating factor must be added to the overall wind speed accuracy of this sensor.

It is highly recommended that the calibration be checked annually

Logger Connections

•For ANALOG output connections (Voltage or Current) , please search for ‘Installation Guide – Analog

Sensors’ on: https://trackso.in/trackso‐installation‐manuals/

•For MODBUS output connections, please search for ‘Installation Guide – MODBUS Sensors’ on:

https://trackso.in/trackso‐installation‐manuals/

Sensor Maintenance

•Maintenance includes inspection of mechanical operation and cleaning.

•Rotate wind cup assembly; look for smooth rotation and a gradual stop. If the cup wheel or the vane is not

rotating smoothly or it creates detectable noise, the bearings must be replaced

•Inspect mounting hardware for secure fasteners; mounting pipe must be vertical.

•Replace any loose or corroded fasteners.

•Inspect the cable and connections.

•It is recommended to check the ball bearings of the anemometer every year. If the cup wheel is not rotating

smoothly or it creates detectable noise, the bearings/sensors must be replaced.

•Clean any accumulation of dirt, dust, or bird droppings that may affect proper rotation of the wind speed sensor.

Use only soapy water and a soft cloth. Never use solvents or abrasive cleansers. Do not immerse the

anemometer in water.

Troubleshooting

Situation

Comments

If wind speed seems low

•A stiff bearing on the wind cups shaft‐ Use an Allen wrench to loosen the setscrew on

the side of the wind cups. Remove the wind cups, and also clean the exposed portion of

the shaft with a damp cloth or cotton swab. After tightening the setscrew, check to

make sure that the wind cups spin freely. If they do not, the bearings may be worn and

need factory repair.

•If all of the potential causes of zero wind speed listed above can be ruled out then it is

highly probable that the recorded wind speeds are essentially correct but anemometer

exposure is suboptimal. Get the anemometer up high and do so in as open a space as is

available.

High wind speed spikes

•Moisture getting into the PCB, sockets into which the anemometer cable is plugged.

•

Earth/ground issues where a ground loop is the culprit.

No Wind speed

detected

•Loss of supply voltage. Check +12 supply & connecting cables

•Faulty detector. Replace detector

Disclaimer

This sensor is a low‐cost alternative to the Class 1/Class 2 sensors of the same type. Since this sensor fall under no class,

there will be some variation in the real vs. expected values. If you wish to minimise the error/deviation in output values,

we recommend that you purchase Class 1/Class 2 sensor.
