What is a Solar PV Module Temperature Sensor?

A Solar PV Module Temperature Sensor, like the RK220 - 01, is a specialized device designed to measure the temperature of solar photovoltaic modules. According to industry standards such as IEC 61724 - 1, these sensors are typically placed at the back of the module, close to the center of a cell, avoiding cell boundaries.

The RK220 - 01 uses high - precision platinum resistance (PT100) as its sensing component. It works on the principle that the electrical resistance of platinum changes with temperature, allowing for accurate temperature measurement. The sensor can then convert the temperature data into various output signals for further analysis and monitoring.RK220 - 01 采用高精度铂电阻（PT100）作为其传感元件。它基于铂的电阻随温度变化这一原理工作，从而实现精确的温度测量。传感器随后可将温度数据转换为各种输出信号，以便进一步分析和监测。RK220 - 01 采用高精度铂电阻（PT100）作为其传感元件。它基于铂的电阻随温度变化这一原理工作，从而实现精确的温度测量。传感器随后可将温度数据转换为各种输出信号，以便进一步分析和监测。
