Overview

CS240 PT-1000 Class A, BACK OF Module TEMPERATURE SENSOR (-40 to +135C)

The CS240 is a surface mountable PRT that measures back-of-module temperature for solar energy applications. It uses a precision Pt-1000 class A PRT to provide the highest level of accuracy. To withstand the harsh treatment commonly seen in MET station installation, the PRT is safely housed inside a specially designed self-adhesive aluminum disk.

Key Advantages

Proven Rugged Design
Class A accuracy at any cable length

Technical Description

The CS240 consists of a Pt-1000 class A PRT encased in an aluminum disk. The disk protects the PRT, particularly during installation when pulled through conduit, and promotes heat transfer from the surface. An adhesive tab on the disk fastens the CS240 to the measurement surface. If the temperature may exceed 70°C, Extreme sealing tape is also required to secure the probe.

The CS240 provides PV stakeholders with highly accurate back-of-module temperature, even at long cable lengths, for use in power performance modeling and simulation of solar energy applications. Back-of-module temperature is critical for any evaluation of effective irradiance and power conversion.
