Product Introduction
YGC-JYZ Photovoltaic Total Radiation Sensor (Transmitter) can be used to measure the total solar radiation in the spectral range of 0.3-1.1 μm. If the sensing surface is facing downward, it can measure reflected radiation, and with a shading ring, it can measure scattered radiation. The core component of the radiation sensor is a high-precision photosensitive element with excellent stability and high accuracy. Additionally, a quartz glass dome, precision-crafted through optical cold processing, is installed outside the sensing element to effectively prevent environmental factors from affecting its performance. This product is widely applicable in fields such as meteorology, energy, agriculture, and construction.

Calculation Formulas
| Current Output |
F: Total radiation value, unit: W/m² I: Sensor output current, unit: mA V: Sensor output voltage, unit: V |
|
| 4-20mA | F =（I - 4）/ 16 * 1500 | |
| 0-20mA | F = I / 20 * 1500 | |
| Voltage Output | ||
| 0-2.5V | F = V/ 2.5 * 1500 | |
| 0-5V | F = V / 5 * 1500 | |
Wiring Method
(1) If the sensor is equipped with our company’s instrument: Simply connect the sensor directly to the corresponding interface on the instrument using the sensor cable.
