=] SCIENTIFIC WHEN MEASUREMENTS MATTER o et = (o= C5240DM Pt-1000 Class A, Back-of-Module Temperature Sensor with Digital Overview The CS240DM is a best-in-class smart sensor with a rugged, surface-mountable platinum resistive thermometer (PRT) that measures back-of-module temperature on solar photovoltaic (PV) panels. The C5240DM includes a new Benefits and Features ) Best-in-class measurement accuracy and technology ) Modbus RTU RS-485 digital serial communications ) Precision Pt1000 Class A sensing element ) Compliant with IEC 60751, DIN EN 60751 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 transfer from the 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, Modbus RS-485 Output Proven, Rugged Design Class A accuracy, best-in-class performance Campbell Scientific precision analogue-to-digital, smart- sensor module that makes back-of-module temperature measurements that are among the most accurate measurements available today. ) Meets 61724-1 PV System Performance Standard ) Optional NIST traceable calibration certificate ) Purchased with any cable length ) Rugged design proven in more than 4,000 installations worldwide 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. For comprehensive details, visit: www.campbellsci.eu/cs240dm ‘
