Solar Radiation Sensor Mounts 1. Introduction
The CM225, CM255, CM256, CM261, CM275, and 015ARM solar radiation sensor mounts (FIGURE 1-1) are designed to be mounted on a mast, crossarm, or pole. The mounting holes on the top plate allow a wide variety of sensors to be mounted. The CM256, CM261, and CM275 have four different mounting plate options to allow a larger number of sensors to use the mount. In addition, the CM261 has three torque tube mounting options.
The CM226 is designed to mount on a mast, crossarm, or pole up to 5 cm (2 in) diameter. This mount includes the leveling base required by smaller sensors such as the Apogee CS301.
The CM225 is designed to be mounted either horizontally to a crossarm or vertically to a mast or a pole to keep the mounting plate level. The CM255 and CM256 can also be mounted horizontally or vertically, but include a 90 adjustment. This allows the mount to be positioned at different angles, as shown in FIGURE 4-1. The CM261 is designed specifically for securing a pyranometer near the end cap of an ATI or NexTracker torque tube. It can also be used with any other 12.7 cm (5 in) diameter tube. The CM275 is a universal solar albedo mounting stand to mount any downwelling/upwelling combination of pyranometer, ventilation unit, reference cell, or spectral radiometer. The 015ARM mounts to a vertical mast or tripod.

2. Precautions READ AND UNDERSTAND the Safety section at the back of this
manual.
WARNING Ensure the mounting bracket is securely fastened during setup and weather extremes to minimize the chance of damaging the instruments. Read all instructions carefully.
3. Initial Inspection Upon receiving the solar radiation sensor mount, inspect the packaging
and contents for damage. Claims for shipping damage must be filed with the shipping company.
Locate the packing slip for the order and compare the items listed on the packing slip to the items that were actually shipped. Report any discrepancies to Campbell Scientific.
4. Overview Campbell Scientific solar radiation sensor mounts provide a stable mounting platform for a pyranometer, quantum sensor, or radiometer. The flexibility in these designs allows a sensor to be mounted to a horizontal crossarm, or to a vertical mast or tower. The CM255 and CM256 may be mounted at different angles, depending on the users needs (FIGURE 4-1). The CM275 allows the mounting of a downwelling/upwelling combination of pyranometer, ventilation, reference cell, or spectral radiometer. With the 015ARM, the sensor is mounted away from the vertical pipe, allowing for a more unobstructed view of the sky.

6. Installation 6.1 Siting
The solar radiation sensor is usually installed horizontally, but can also be installed at any angle including an inverted position. In all cases, it will measure the flux that is incident on the surface parallel to the sensor surface. Site the sensor to allow easy access for maintenance while ideally avoiding any obstructions or reflections above the plane of the sensing element. Mount the sensor such that a shadow or a reflection will not be cast on it at any time. FIGURE 6-1 shows how to calculate the distance needed from any potential obstruction.
FIGURE 6-1. Solar sensor placement

If this is not possible, try to choose a site where any obstruction over the azimuth range between earliest sunrise and latest sunset has an elevation not exceeding 5. Diffuse solar radiation is less influenced by obstructions near the horizon. For instance, an obstruction with an elevation of 5 over the whole azimuth range of 360 decreases the downward diffuse solar radiation by only 0.8%. The sensor should be mounted with the cable pointing towards the nearest magnetic pole. For example, in the Northern Hemisphere, point the cable toward the North Pole.
6.2 Installation 1. On a level surface, level the solar radiation sensor using the leveling feet
on the sensor. Alternatively, remove the sensor leveling feet to allow it to be mounted directly to the mounting bracket. Smaller sensors, such as the CS301, do not have leveling feet and must be mounted directly to a leveling base.
2. Secure the solar radiation sensor to the mounting bracket. Refer to FIGURE 6-2 to determine which mounting holes are used by the sensor. Visually inspect the leveling feet on the sensor (if present) to ensure all feet are in contact with the mounting bracket.

3. Using a diopter in combination with a solar compass, install and orient the crossarm on the tripod or the mast. If installing the mounting bracket on a vertical pole, ensure the pole is truly vertical.
4. Secure the mounting bracket to the crossarm or the vertical pole using the hardware included with the mounting bracket. The CM225, CM255, CM261, and 015ARM use one or two U-bolts, nuts, flat washers, and lock washers to mount the bracket (FIGURE 6-3).

5. The CM256 and CM275 bracket (FIGURE 6-4) use two set screws to secure the crossarm or the pole in the channel at the base of the bracket. For pyranometers mounted horizontally, ensure the mounting bracket is horizontal in two dimensions. For pyranometers to be mounted at an angle with the CM255 or CM256, set the mounting bracket angle to the desired angle prior to tightening the mounting hardware.
FIGURE 6-4. CM256 (CM275 inset)
6. The CM226 uses two bolts, wing nuts, and a clamp piece to secure it to a crossarm or mast (FIGURE 6-5).
