OrderableClass A Spectrally Flat and Fast-Response Pyranometer with Integrated Dome Heater
Overview
The MS-80SH, manufactured by EKO Instruments, is an innovative, next-generation ISO 9060 Class A spectrally flat and fast-response (secondary standard) pyranometer. The pyranometer features a compact design with internal desiccation, a single dome over a quartz diffusor, a thermally isolated thermopile detector, negligible thermal offsets, ultra-low temperature dependency, and exceptional non-linearity characteristics. The MS-80SH has a five-year warranty and recalibration interval.
EKO instruments is the longest-operating ISO 17025-accredited pyranometer manufacturer in the world. This allows for the highest-quality calibration and for Campbell Scientific to comply with international standards (ISO/IEC 17025 for ISO 9847).

(10)CM256
Adjustable Plane and Angle Solar Mounting Stand
The CM256 adjustable-angle, adjustable-plane mounting stand further simplifies the accurate and precise mounting of a pyranometer, ventilation unit, shadowband radiometer, or reference cell. Several pyranometer mounting stands have been combined and simplified to make ordering easier and usability friendlier. The CM256 is a combination of the CM255LS pyranometer mount, CM245 reference cell and shadowband mount, 31394 VU01 mount, and 31153 CVF4 mount. In addition, several new sensors are now fully supported such as the SPN1, MS-80(M), SR30, SR05, and IMT reference cell CM325.
OrderableCM261
Single-Axis Tracker Mounting Stand
The CM261 single-axis tracker pyranometer mount with adjustable plane simplifies the mounting of any pyranometer, ventilation unit, reference cell, or SPN1 to octagonal, round, and square single-axis torque tubes. The CM261 is a combination and simplification of the CM260 and CM265 to make ordering easier and usability friendlier. The bracket includes provisions for mounting the sensors and ventilation units at different heights, allowing the sensing element to be mounted at the same height as the solar modules.
OrderableCM275
Albedometer Mounting Kit
The CM275 is a universal solar albedo mounting stand for mounting any downwelling/upwelling combination of pyranometer, ventilation unit, reference cell, or spectral radiometer.
OrderableCM255
Solar Adjustable-Angle Mounting Stand
The CM255 is used for most applications that require mounting a solar sensor at adjustable angles. The CM255 includes slots that can be adjusted to any angle from horizontal to vertical. The mounting stand is designed to work with masts, crossarms, or poles that have a 2.5 to 3.8 cm (1.0 to 1.5 in.) outer diameter. It is not designed for applications using a rotating shadowband radiometer (RSR).
OrderableCMB200
Crossarm Brace Kit
The CMB200 Crossarm Brace Kit is designed to provide additional stability to the CM203, CM204, or CM206 crossarms 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.
OrderableCM266
Unistrut Mount
The CM266 is a true universal irradiance sensor mount. Its design makes use of the ubiquitous construction material, Unistrut. Attach your irradiance sensors anywhere you can mount a section of Unistrut.
OrderableCM268
PV Module Mount
The CM268 irradiance sensor mount is designed so you can make irradiance measurements as close to the modules/panels as possible. The mount can be clamped to the panel side, allowing for more representative and distributed measurements throughout the array. Note: Although the CM268 is designed to fit many solar frames, Campbell Scientific recommends confirming that the frame of the intended solar panel is compatible with the mount.
OrderableCM410
Pile Mount Arm (no finish or matte black finish)
The CM410 is used primarily to mount a pair of pyranometers to a driven pile, leveraging the CM275 Albedometer Mounting Kit. The included 15.24 cm (6.0 in.) hook bolts accommodate an I-beam style pile with flange dimensions 7.6 to 12.7 cm (3 to 5 in.), such as a W6x12. Albedo is a common measurement parameter selected for a SunSentry Solar Operational Meteorological Monitoring Station. Installation details, including the recommended pile exposure height and orientation, are found in the SunSentry Installation Guide. To minimize localized glare and reflections that can adversely influence albedo measurements, the all-black version of the CM410 is recommended for albedo.
Orderable44338
RS485CBL Adapter for SunSentry Used with Digital EKO Pyranometer
The 44338 adapter enables a single trunk-line cable to connect an array-mounted digital EKO pyranometer to the SunSentry Solar Operational Meteorological Monitoring Station. The adapter remaps the pin assignments between the two interfaces so the pyranometer is fully compatible with the RS485CBL 24 AWG RS-485 Cable with M12 Five-Pin Connector in a daisy chain with other sensors. The 44338 routes the cable shield through the connector's coupling nut, improving surge protection and reducing signal noise for more reliable operation.
OrderableRS485CBL
Five-Conductor Cable with M12 Five-Pin A-Coded Connector
The RS485CBL cable uses a five-conductor shielded cable with an M12 five-pin A-coded connector. The cable has a polyurethane jacket that is UV resistant. The RS485CBL has been custom designed for sensors that use the RS-485 Modbus protocol with integrated power and signal lines. The signal lines have twisted pairs with 24-gauge conductors, and the power lines have a heavier 20-gauge wire, making the cable uniquely suitable for sensors with a higher current draw that have either short or long runs. An aluminum Mylar shield is grounded via a drain wire and connected to the M12 nut.
