Orderable3 ft Crossarm with One CM210 Mounting Kit
Overview
The CM203 is a 3 ft crossarm that attaches to an instrument tower or tripod. It provides a rugged, weather-resistant sensor mount for one sensor (typically). The CM203 is compatible with our tripods and towers. It can also be attached to a user-supplied pole.
Technical Description
The CM203 provides a rugged, weather-resistant sensor mount for one sensor (typically). It consists of a 1 m (3 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 in. to 2.1 in. OD). All of our tripods and towers are compatible with the CM203.
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 tab.

Crossarm Brace Kit
The CMB200 Crossarm Brace Kit is designed to provide additional stability to the CM203 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 crossarm.
OrderableCM225
Solar Sensor Mounting Stand
The CM225 can attach one pyranometer or quantum sensor to the crossarm.
OrderableCM235
Magnetic Mounting Stand
The CM235 can attach one peripheral with a magnetic base to this crossarm. Devices that have a magnetic base include our GPS16X-HVS Geographic Position Receiver, GPS antennas, and some short-range omnidirectional antennas.

10-Plate Solar Radiation Shield
This 10-plate Gill radiation shield accommodates one HC2S3 temperature and RH 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 radiation shield accommodates one 107, 108, 109, HMP60, or CS215 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.
