带有温度传感器的太阳辐射传感器3 s-sr-t-i / U

模拟输出

该辐射传感器用于测量具有模拟输入数据记录仪的太阳能光伏电站的辐射通量密度。除了辐照传感器，它还包括一个内部模块温度传感器。它随安装支架和电缆一起提供。硅太阳能电池可以用作辐照度传感器，因为短路电流与辐照度成正比。我们的传感器由一个单晶太阳能电池组成，并连接到一个分流器上。由于分路电阻低，电池工作在短路附近。短路电流的温度系数产生的误差很小。这种补偿是通过在太阳能电池的背面叠加一个特定的温度传感器来实现的。利用单片机对电池短路电流的测量信号和温度传感器的电阻值进行测量。辐照度和温度的计算值给出4-20mA或0-10V与客户规范协议。 The electronic circuit is optimized for low power consumption. MECHANICAL CONSTRUCTION The solar cell is embedded in Ethylene- Vinyl- Acetate (EVA) between glass and Tedlar. Plain integration into the top cover of the box Advanced weatherproof junction box made of UV resistant material with cable gland and screw-less terminal for the connection of the measuring cable, therefore, the sensor construction is comparable to that of a standard PV module. The electrical connection is realized by a 3m cable.
