Detailed 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.
