110PV 是直接接触式测量表面温度的热敏电阻。专为监测太阳光电模块温度设计，也可用于监测其它设备的温度。其易于与我们的数据采集器连接，是太阳能领域的理想选择。
优势与特点
- 测量温度，更宽的测量量程：-40° 到 +135°C
- 易于安装 — 110PV平滑表面的粘性条附着到太阳能板的背面或其它设备上
- 铝圆盘保护热敏电阻并促进来自表面的热扩散
- 在重度电磁干扰的环境中进行精确的测量
- 兼容CWS900系列接口，可用于无线的传感器网络中

技术说明
110PV包括一个置于铝盘中的热敏电阻。铝盘可保护热敏电阻并提高表面热传导能力。探头’s上附有标签，使铝盘将110PV固定在测量物体表面。如温度超过70°C ，用Kapton tape保护探头，Kapton tape也是常用的配件，可见订购信息。
110PV可为光伏能源应用提供光电模块温度。这种测量是非常有用的，因为PV模块的输出受温度的影响，随着PV模块温度的上升，输出会减弱。

Additional Compatibility Information
Mounting
For temperatures up to 70°C, an adhesive tab on the probe’s aluminum disk fastens the 110PV to the measurement surface. If the temperature may exceed 70°C, Kapton tape is recommended to secure the probe to the measurement surface. Kapton tape is available from Campbell Scientific (see Ordering Information).
The 110PV can be submerged to 50 ft, but the probe’s adhesive tab is not intended for submersion. Therefore the 110PV must be mounted to the measurement surface via a user-supplied method that is compatible with submersion.
Data Logger Considerations
Programming
The CR200(X)-series dataloggers use the ExDelSe instruction to measure the 110PV. The CR800, CR850, CR1000, CR3000, CR5000, and CR9000(X) can use either the BrHalf4W instruction or BrHalf instruction to measure the 110PV. For these data loggers, the BrHalf4W instruction is typically preferred because it reduces cable errors. The BrHalf instruction requires fewer input channels.
In Edlog, Instruction 5 is typically used to measure the 110PV. The ratio metric output is then converted to resistance and finally to temperature.

-
NIST traceability provides an assurance of accuracy. This is especially desirable in accordance with IEC 61724, which is a specification for monitoring solar energy generation that requires calibrated sensors.
-
Yes. After adhering the sensor to a dry surface, the sensor can be submerged up to 50 ft in depth.
-
There is no outside visual damage bending the cable over on itself 180°. But for long-term durability purposes, any bends should not be smaller than a 0.5 in. radius.
-
The sensor behaves exceptionally well (temperature uncertainty <0.2°C) between -40 and +80 degrees Celsius.
-
Yes, which means it can be wired directly to a data logger.
-
In either a 3-wire or 4-wire half-bridge configuration. For details, refer to the 110PV-L Instruction Manual.
-
That depends on which data logger is being used and how the 110PV-L has been wired. For more details, see the 110PV-L Instruction Manual.
-
Currently, Short Cut only offers a half-bridge measurement option, and the resistance is not calculated. Each cable resistance is measured at the factory and labeled with its unique reading. That resistance value is called for when adding a 110PV-L sensor to the Short Cut program.
-
Some of the more common readings that indicate a sensor is malfunctioning include NANs (not a number) or unrealistic values such as a panel temperature reading of 500 degrees Celsius. If NANs occur, it is possible that there may be either programming or wiring errors. Double-check the setup, and contact Campbell Scientific for assistance if the issue continues. Depending on the sensor behavior, the sensor may need to be returned to Campbell Scientific for repair.
-
When these sensors are purchased, the following calibration services are offered: TEMPCAL and TEMPCAL2.
- TEMPCAL provides a single-point calibration and a calibration certificate. The single-point calibration determines the offset at 25°C with an uncertainty of ±0.05°C.
- TEMPCAL2 provides a two-point calibration and a calibration certificate. The two-point calibration determines offsets at 30°C and 65°C with an uncertainty of ±0.05°C.
For both of these services, calibration can be made at different values if it is requested by the purchaser at the time of purchase. In addition, both of these calibration services can be requested after sensor purchase using a return material authorization (RMA) number. To request an RMA number, refer to the Repair and Calibration page.
