Introduction to Sensor
The CS241 Pt-1000 Class A Back-of-Module Temperature Sensor is designed for accurate temperature measurement on bifacial PV modules. Featuring a precision Pt-1000 Class A element, it meets IEC 61724 Class A performance standards and includes a NIST-traceable calibration certificate. Its slim, low-profile design minimizes shading impact while ensuring strong thermal bonding to the module. With an IP68 rating and a high temperature tolerance up to 150°C, the CS241 is ideal for long-term outdoor and floating solar applications.
