1 FORWARD
Thank you for purchasing NovaLynx products. NovaLynx has been designing and manufacturing
weather instruments since 1988. NovaLynx represents several well-known brands of quality
manufacturers, including Gill Instruments, RM Young, Kipp & Zonen, and Vaisala. It is our hope that our
products will meet all your monitoring requirements.
2 INTRODUCTION
WeatherPort 200-WS-01 Wind Sensors are moderately priced anemometers designed for general
applications up to 125 mph (56 m/s). The sensors are easy to install and maintain. They are
constructed of injection molded thermoplastic, anodized aluminum, and stainless steel for reliable
operation in adverse environments.
The base of the sensor is designed to mount on a vertical 1.07" (27 mm)
diameter mast. If the sensor cannot be mounted at the top of the mast,
an optional side-mount boom (NovaLynx 200-153) is available.
Most versions of the 200-WS-01x sensor include 40 feet (12 m) of cable.
The cable is attached to the side of the sensor, as shown in the photo, or
it exits the base. Be aware that if the cable exits the base, it must be
threaded through the supporting mast. Cable (Side Exit)
The 200-WS-01 is a cup-style anemometer. One or more permanent magnets in the rotating cup
assembly cause a reed switch in the base to close momentarily, so that the frequency of pulses is
proportional to wind velocity, and the number of pulses is proportional to distance.
Sensors designed for monitoring wind speed output 3 pulses per revolution (3 ppr).
Sensors designed for monitoring wind run output 1 pulse per revolution (1 ppr).
3 PRECAUTIONS
Handle the sensor carefully as the cup assembly is fragile. Do not lay the sensor on its side which would
place strain on the cup assembly.
The shield wire in the sensor cable is electrically connected to the shaft holding the bearing / cup
assembly. The purpose is to bleed off static that would otherwise affect the sensor output. Therefore it
is important to earth ground the shield wire for best results.
Installations where nearby lightning strikes are likely should include a properly grounded lightning rod
above the level of the sensor, preferably on a separate tower.

revolution of the cups, reducing demands on an electronic counter compared to the three-pulses per
revolution of the wind speed sensors.
The calibration constant for wind run is 960 pulses per mile (596.5 pulses per kilometer). The reciprocal
of these numbers gives the value of each pulse: 0.001042 miles per pulse (0.001676 km per pulse).
5.2 Wind Speed Sensors
WeatherPort wind speed sensors produce three switch closures for each revolution of the cup
assembly. The ratio of closed-to-open time is nominally 1/10 of the total period for a revolution of the
wind cups. This duty cycle may change slightly as the sensor ages and with exposure to temperature
extremes.
Note: Model 200-WS-01B-TS has a slightly higher starting threshold due to a characteristic of the Teflon
bearing.
6 SITE SELECTION
WARNING: Avoid overhead power lines whenever possible. If there are overhead power lines, use
extreme care to prevent contact with the power lines while installing the equipment.
Choose a mounting location for the wind sensor that is free of obstructions since nearby objects can
create eddy currents that will affect the wind measurements. Try to locate the wind sensor so that the
nearest object is 10 x T away from the wind sensor mast, where T is the height of the object.
Roof mounted sensors should be placed on the upwind side of the building and away from all exhaust
vents. If the sensor is located on top of a building the sensor height should be 1.5 x H, where H is the
height of the building.
In all cases when the wind sensor data is to be correlated to National Weather Service data or World
Meteorological Organization data, the standard exposure is 33 feet (10 meters) above the ground.

7 MOUNTING OPTIONS
CAUTION: Be careful when working on equipment that is mounted above you. Do not allow others to
stand below when equipment is being installed as falling objects can be hazardous.
The support for the sensor must be rigid or supplemented with guy wires. A mast can be assembled
from pipe, using larger pipe at the base and ending in ¾" IPS pipe at the top. The mast should be easy
to reach for servicing the sensor and should be properly anchored and grounded. A tilt-down
arrangement can eliminate the need for lifts or ladders during installation and service.
NovaLynx tripods are a convenient alternative for temporary and permanent installations. The tripods
are available in three sizes: 3', 5' and 10' tall (Appendix A). Masts are available in various lengths.
Swaged mast segments can be fitted together to obtain the overall height needed. The swaged end is
the correct diameter for mounting 200-WS-01x sensors.
1.07" 1.25"
SWAGED ALUMINUM MAST
3.75"
The base of the 200-WS-01 sensor accepts 1.07" (27 mm) diameter pipe. To assemble the sensor to the
pipe, simply loosen the two mounting screws on the base of the sensor, slip the sensor onto the pipe,
and tighten the screws using moderate torque. Note, if the cable exits the bottom, the cable will have
to be fed through the pipe before placing the sensor.
If the wind speed sensor cannot be mounted at the top
of the mast, the NovaLynx 200-153 Mounting Arm (sold
separately) can be mounted to the mast or tower leg at
the desired height.
200-153 Mounting Arm
The supporting mast or tripod should be properly grounded. In areas where lightning is likely, install a
lightning rod to minimize lightning damage. NovaLynx 190-Series Lightning and Surge Protection
products are available to accommodate most applications.

8 INSTALLATION
1. Loosen the two mounting screws on the base of the sensor.
2. Place the sensor on the top of the mast or mounting stub.
3. Tighten the mounting screws using moderate torque.
The PVC jacket of the cable will last for many years outdoors under normal circumstances. In harsh
environments it may be necessary to protect the cable with conduit.
Route the sensor cable down the mast and to the monitoring equipment in the most direct manner.
Fasten the cable to the mast with cable ties to prevent whipping during high velocity winds. For best
results, use plastic cable ties that are resistant to ultra-violet radiation and place them at two foot
intervals. Leave a "drip loop" of cable below the entry point to the equipment enclosure to help keep
moisture out.
Turn off power to the logger or other monitoring device before connecting the sensor.

NOTE: The reed switch output is "dry contact". A pull-up resistor may be needed on the input channel to
monitor the switch closure.
9 MAINTENANCE
Wind sensors experience vibration due to high velocity wind. The vibration can loosen the mounting
screws or the support structure. Regular inspection of the mounting hardware is required to prevent
damage to the sensor.
1. Tighten the mounting screws if necessary (do not over-tighten).
NovaLynx Corporation
200-WS-01 Page 9 April 2021
2. Spin the anemometer cup assembly. It should turn freely. Apply a few drops of light machine oil
(e.g. fishing reel oil) to the bearing if needed. Note: Do not use WD-40 or similar products, as they
wear off quickly, leaving the bearing dry and susceptible to rust.
3. Inspect the cable and ensure it is secured to the mast to prevent damage due to wind whipping.
4. If one of the cup arms is damaged, the sensor may be user-repairable. Order the NovaLynx kit that
matches your sensor:

2502-14-01C 1-magnet wind cup assembly for wind run sensors
10 FUNCTIONAL TESTS
The following checks can be done with an ohm-meter after the sensor has been dismounted from the
tower or tripod. These tests can help determine whether the sensor needs repair or adjustment.
Set the ohm-meter to a low resistance range and touch its leads together to check for zero ohms. If it is
an analog meter adjust the dial to read zero ohms. Connect the ohm-meter to the signal wires from the
anemometer (polarity is not important).
Rotate the cup assembly slowly until you notice the meter reading drop to less than 10 ohms. Continue
to rotate until the switch opens. Do this for each of the magnets in the cup assembly (3 magnets in
wind speed models, 1 magnet in wind run models).
If the meter always reads a low resistance then the reed switch is not opening (the contacts
may have welded together) or there may be a short circuit in the cable.
If the switch never closes then there may be a break in the cable or the magnets are not near
enough to activate the switch. Check the distance between the cup assembly and the base. The
gap should be about 1/16" (1.6 mm).
