CM206
Orderable6 ft Crossarm with One CM210 Mounting Kit
Overview
The CM206 is a crossarm that attaches to an instrumentation tower or tripod. It provides a rugged, weather-resistant sensor mount for up to two sensors. The CM206 is compatible with our tripods and towers. It can be attached to a tripod mast or a user-supplied pole.
Note: In the image, the dark gray components are those included with the CM206. The lighter components are sold separately and demonstrate how the CM206 is used.
Technical Description
The CM206 provides a rugged, weather-resistant sensor mount for one or two sensors. It consists of a 6-ft aluminum pipe and the CM210 mounting bracket kit. U-bolts included with the mounting bracket are used to attach the crossarm to a tripod mast, tower leg, or user-supplied vertical pipe (1.0” to 2.1” OD). All of our tripods and towers are compatible with the CM206. If the CM206 will be mounted on a tower, an additional CM210 bracket can be added so that the crossarm is secured to two of the three vertical risers within the tower.
A U-bolt mounting scheme allows the crossarm to be secured to the tripod or tower at the optimal measurement height for the sensor. The sensor is then mounted to the other end of the crossarm using a variety of mounts—depending on the sensor being deployed. The options available for mounting the sensor to the crossarm are listed as Common Accessories under the Ordering Info tab.

1- x 1-in. Nu-Rail Crossover Fitting
The 17593 NU-RAIL® Slip-on Offset Crossover Fitting is used to mount a sensor with a 1.0" IPS mounting pipe (typically a wind sensor) to the crossarm. It provides equivalent functionality as the CM220 Right Angle Mounting Bracket.
Orderable1049
3/4 x 1 in. Nu-Rail Crossover Fitting
The 1049 NU-RAIL® Crossover Fitting is used to mount a sensor with a 0.75" IPS mounting pipe (typically a wind sensor) to the crossarm. It provides equivalent functionality as the CM220 Right Angle Mounting Bracket.
OrderableCMB200
Crossarm Brace Kit
The CMB200 Crossarm Brace Kit is designed to provide additional stability to the CM206 crossarm mounted on Campbell Scientific tripods and towers. This kit provides support for crossarms with heavier or sensitive sensor loads, as well as added stability in higher winds. Each kit includes one brace arm and three sets of mounting brackets.
OrderableCM221
Right-Angle Mounting Kit
The CM221 mounts a pipe or tube at 90° to another pipe or tube. It is typically used to attach a sensor with a vertical pipe (including most wind sensors) to a crossarm. The cast aluminum, right-angle mounting bracket has 3.8 cm (1.5 in.) U-bolts and hardware and will accommodate tubing with a 1- to 1.5-in. outer diameter.
OrderableCM230
Adjustable Inclination Mounting Kit
The CM230 Adjustable Inclination Mount secures a directional (Yagi) antenna or a sensor that must be pointed at a specific target (e.g., SI-111, SR50A) to the CM206.
OrderableCM225
Solar Sensor Mounting Stand
The CM225 can attach one pyranometer or quantum sensor to a CM206 crossarm.
OrderableCM235
Magnetic Mounting Stand
The CM235 can attach one peripheral with a magnetic base (typically antennas) to a CM206 crossarm. Devices that have a magnetic base include our GPS16X-HVS Geographic Position Receiver, GPS antennas, and some short-range omnidirectional antennas.
OrderableCM210
Crossarm-to-Pole Mounting Kit
The CM210 is included with this crossarm. An additional CM210 may be useful if the crossarm will be mounted on a tower. The additional CM210 allows the crossarm to be secured to two of the three vertical risers within the tower.

10-Plate Solar Radiation Shield
This 10-plate Gill radiation shield accommodates one HMP45C probe. The shield's louvered construction allows air to pass freely through the shield thereby keeping the probe at or near ambient temperature.
Orderable41303-5A
6-Plate Solar Radiation Shield
This 6-plate Gill radiation shield accommodates one 107, 108, or HMP60 probe. The shield's louvered construction allows air to pass freely through the shield thereby keeping the probe at or near ambient temperature.
OrderableRAD06
6-Plate Solar Radiation Shield
The RAD06 uses a double-louvered design that offers improved sensor protection from driving rain, snow, and insect intrusion. It also has lower self-heating in bright sunlight combined with higher temperatures (> 24°C (~75°F)) and low wind speeds (< 2m/s (~4.5 mph)), providing a better measurement.
OrderableRAD10E
10-Plate Solar Radiation Shield for Larger Sensors
The RAD10E uses a double-louvered design that offers improved sensor protection from driving rain, snow, and insect intrusion.
OrderableRAD14
14-Plate Solar Radiation Shield
The RAD14 uses a double-louvered design that offers improved sensor protection from driving rain, snow, and insect intrusion.
