Wiring of SR20-T1 to CR1000


RosarioIac Jan 18, 2023 02:21 PM

Hello,

I am trying to wire a SR20-T1 pyranometer to a CR1000 datalogger. The pyranometer has an internal thermometer based on a Pt100 sensor that it uses to correct the reading. The sensor is meant to be wired as any Pt100. Campbell suggests to use a 4 wire double bridge connection through a 4WPB100 adapter. I would like to do the connection without the adapter using a 10K and a 100 ohm resistors. Has someone ever done it? I am looking for the pinout.

Thanks.
