Technical Description

The CS240DM 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 transfrfome rth e surface while minimizing convective heat loss to the surroundings. An adhesive tab on the disk fastens the C5240DM to the measurement surface. If the temperature may exceed 70°C, Kapton tape is also required to secure the probe.

The precision analog-to-digital, smart-sensor module is based on the CR1000X. The module design is optimized for the Class A PRT that minimizes self-heating and lead-wire resistance. Measurement electronics are surge protected, include 1200V isolation, and are environmentally protected with a rugged over-molding featuring an IP65 rating. Data is differentially transmitted in cabling that is well suited for industrial energy applications with excellent noise rejection and high voltage, NEC outdoor, UV, UL, and NEC ratings.

The CS240DM 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.
