The CS240 is a surface mountable PT1000 Class A PRT designed to measure back-of-panel temperature with the highest accuracy. The PRT is housed inside a rugged, self-adhesive aluminum disk designed to withstand harsh environments and promote heat transfer from panel surface. Kapton tape is required for cable strain relief and to fasten the CS240 to the back of a solar panel.
