Common Accessories

CM255
 
One stand is needed per pyranometer. The CM255 is one of two options. The CM255 is used to mount the SR20-T2-L at an angle.
CM256
 
CM256 Adjustable Plane & 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.

This mounting plate option is compatible with the following: MS-40/60/80, MS-40M/60M/80M, SR30, SR05, SR11, SR15, SR20-T2, SR20-D2, SP Lite 2, CMP3/6/10/11/21/22, SMP3/6/10/11/21/22, CGR3/4, and SGR3/4.
-LP -LP w/Large Mount Plate
This mounting plate option is compatible with the following: SPN1, PSP, GPP, SPP, and Si-01TC Reference Cell (CS325DM).
-VN -VN w/VU01 or MV-01 Plate
This mounting plate option is compatible with the following: VU01 and MV-01.
-CV -CV w/CVF4 Plate
This mounting plate option is compatible with the following: CVF4.
VU01-L
 
VU01-L Hukseflux Ventilation Unit for SR20
 
The VU01, manufactured by Hukseflux Thermal Sensor, is a high-quality ventilation unit for use with pyranometers and pyrgeometers. Its purpose is to improve the dependability of the measurement.
VU01-L Options - show details
-L ft cable per sensor

Allowed values: 0-17 ft, increments of 1 ft

Cable Termination Options
-PT -PT w/Tinned Wires
-PW -PW w/Pre-Wire Connector
CM261
 
CM261 Single-Axis Tracker Mounting Stand
 
One CM261 is needed per VU01-L. The CM261 single-axis tracker pyranometer mount with adjustable plane simplifies the mounting of any pyranometer, ventilation unit, reference cell, or SPN1 to hexagonal, 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.

CMB200
 
The CMB200 Crossarm Brace Kit is designed to provide additional stability when using a 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.

Replacement Parts

 
SR20-T2CBL-L SR20-T2 Replacement Cable
 
This replacement cable includes a mating connector for the SR20-T2-L and uses raw cable part number 8865. This cable is a 24 AWG, one twisted-pair with seven conductors in a shield with a drain and Santoprene jacket.
SR20-T2CBL-L Options - show details
-L ft per cable

Allowed values: 1-328 ft, increments of 1 ft

Cable Termination Options
-PT -PT w/Tinned Wires
-PW -PW w/Pre-Wire Connector
 
The 32309 is a five-pack of desiccant drying packets for the SR20-T2-L. The humidity indicator for the pyranometer should be inspected periodically. The color blue indicates dryness. A pink color, however, indicates it is humid and the desiccant packet should be replaced.
 
The 34512 is used to secure the SR20-T2-L to the CM255LS Adjustable-Angle Solar Sensor Mounting Stand.
 
The 31373 is commonly used with the 34512 screw to secure the SR20-T2-L to the CM255LS Adjustable-Angle Solar Sensor Mounting Stand.
