Detailed Description

The LI190SB measures solar radiation with a silicon photovoltaic detector mounted in a cosine-corrected head. A shunt resistor in the sensor’s cable converts the signal from microamps to millivolts, allowing the LI190SB to be measured directly by a Campbell Scientific data logger.

LI190SB accurately measures Photosynthetic Photon Flux Density (PPFD), which is the number of photons in the 400 to 700 nm waveband incident per unit time on a unit surface. Because PPFD describes photosynthetic activity, the LI190SB is ideal for growth chambers and greenhouses.

Additional Compatibility Information

坐骑

为了确保准确的测量值，应使用LI2003S级别固定装置对传感器进行平整，该固定装置包含气泡电平和三个调节螺钉。LI2003S平整夹具使用CM225安装座安装在三脚架或塔上。LI190SB应远离所有障碍物和反射表面，这可能会对测量产生不利影响。

Data Logger Considerations

The LI190SB requires one differential analog input channel per probe.

经常问的问题

与li190SB-L：8

Expand AllCollapse All

  1. Is there a variant of the LI190SB-L that comes with a BNC connector?

    此版本是直接从Li-Cor购买的，不会直接与Campbell Scientific Data Loggers合作而没有修改。

  2. What is the difference between the LI190SB-L and the LI200X-L?

    LI190SB-L测量光合活性辐射（PAR），光谱范围是400 nm至700 nm的光谱范围。这是植物在光合作用过程中使用的能量。用LI190SB-L的测量结果据报道为光合光子通量密度（PPFD）。

    LI200X-L的总太阳辐射从400到1100 nm。通常以W/M单位报告测量2。

  3. If a sensor automatically ships with a calibration sheet, what information is included on it?

    校准表上包含的信息与每个传感器不同。对于某些传感器，表包含编程数据记录器所需的系数。对于其他传感器，校准表是通过/失败报告。

  4. 不同的电缆长度是什么choices available for Campbell Scientific sensors?

    大多数坎贝尔科学传感器都可以作为–L提供，该传感器表示用户指定的电缆长度。如果将传感器列为–LX模型（其中“ X”是其他字符），则传感器的电缆具有用户指定的长度，但它用特定的连接器终止了独特系统：

    • –LC模型具有用户指定的电缆长度，可连接到ET107，CS110或已退休METDATA1。
    • An –LQ model has a user-specified cable length for connection to a RAWS-P weather station.

    如果传感器在主型号之后没有–L或其他-LX名称，则传感器具有设置的电缆长度。电缆长度在产品订购信息中的描述字段末尾列出。例如，034B-ET型号的描述说明“遇到了一个为ET站的一组，67英寸电缆”。具有固定电缆长度的产品，默认情况下，带辫子。

    If a cable terminates with a special connector for a unique system, the end of the model number designates which system. For example, the 034B-ET model designates the sensor as a 034B for an ET107 system.

    • –ET模型终止于ET107气象站的连接器终止。
    • –ETM models terminate with the connector for an ET107 weather station, but they also include a special system mounting, which is often convenient when purchasing a replacement part.
    • –QD models terminate with the connector for a RAWS-F Quick Deployment Station.
    • –PW models terminate with the connector for a PWENC or pre-wired system.
  5. 特定传感器列出了可用的电缆终止选项？

    不是每个传感器有不同的电缆终端options. The options available for a particular sensor can be checked by looking in two places in the Ordering information area of the sensor product page:

    • Model number
    • Cable Termination Options list

    If a sensor is offered in an –ET, –ETM, –LC, –LQ, or –QD version, that option’s availability is reflected in the sensor model number. For example, the 034B is offered as the 034B-ET, 034B-ETM, 034B-LC, 034B-LQ, and 034B-QD.

    All of the other cable termination options, if available, are listed on the Ordering information area of the sensor product page under “Cable Termination Options.” For example, the 034B-L Wind Set is offered with the –CWS, –PT, and –PW options, as shown in the Ordering information area of the 034B-L product page.

    笔记：由于通常将较新的产品添加到我们的库存中，因此我们将在单个传感器模型下列出多个电缆终止选项，而不是创建多个模型号。例如，HC2S3-L具有将其连接到CS110而不是提供HC2S3-LC模型的–C电缆终止选项。

  6. 如果原始校准表丢失了，可以请求另一副本吗？

    This depends on the information contained in the calibration sheet:

    • If the calibration sheet contains coefficient information, Campbell Scientific keeps a copy, and a replacement copy can be requested.
    • If the calibration sheet does not contain coefficients, Campbell Scientific does not keep a copy. It may be possible to contact the original manufacturer for a replacement copy.
  7. 坎贝尔科学传感器可用哪些不同的电缆终止选项？

    许多坎贝尔科学传感器都有不同的电缆终止选项。这些选项包括以下内容：

    • The –PT (–PT w/Tinned Wires) option is the default option and does not display on the product line as the other options do. The cable terminates in pigtails that connect directly to a data logger.
    • 在–C（–C W/ET/CS110连接器）选项中，该电缆终止在连接到CS110电场表或Et系列气象站的连接器中。
    • In the –CWS (–CWS w/CWS900 Connector) option, the cable terminates in a connector that attaches to a CWS900-series interface. Connection to a CWS900-series interface allows the sensor to be used in a wireless sensor network.
    • In the –PW (–PW w/Pre-Wire Connector) option, the cable terminates in a connector that attaches to a prewired enclosure.
    • In the –RQ (–RQ w/RAWS Connector) option, the cable terminates in a connector that attaches to a RAWS-P Permanent Remote Automated Weather Station.

    笔记：电缆终止选项的可用性因传感器而异。例如，传感器可能没有，两个或几个选项可供选择。如果未列出特定传感器的所需选项，请联系Campbell Scientific寻求帮助。

  8. 将与无线传感器接口兼容的传感器连接到无线网络中的CR800，CR1000或CR3000需要什么？

    要将与无线传感器接口兼容的传感器合并到无线网络中，需要CWS900系列无线传感器接口，以及A205 CWS-TO-PC接口进行配置。
