Überblick

Der CS240DM ist ein smarter PRT (Platin-Widerstands- Temperatur) Sensor, den man an der Rückwand eines PV-Moduls anbringen kann. The CS240DM includes a new Campbell Scientific precision analog-to-digital, smart-sensor module that makes back-of-module temperature measurements that are among the most accurate measurements available today. The module, based on CR1000X design, is optimized for the Class A PRT and minimizes self-heating and lead-wire resistance. Measurement electronics are surge protected, include 1200 V isolation, and are environmentally protected with a rugged over-molding featuring an IP65 rating. Data is differentially transmitted in twisted-pair cabling, which is well suited for industrial energy applications with excellent noise rejection and high voltage, NEC Outdoor, UV, UL, and NEC ratings.

Kapton tape (pn 11051) is required for cable strain relief. The tape is also used to fasten the sensor to the back of a solar panel when the temperature may exceed 70°C.

Technische Beschreibung

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 transfer from the surface. An adhesive tab on the disk fastens the CS240DM to the measurement surface. If the temperature may exceed 70°C, Kapton tape is also required to secure the probe.

The CS240DM includes a Campbell Scientific precision analog-to-digital, smart-sensor module for making the measurements. The module design is optimized for the class A PRT that minimizes self-heating and lead-wire resistance. Measurement electronics are surge protected with 1200 V isolation and environmentally protected with a rugged overmolding with an IP65 rating.

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.
