1. What are the part numbers to order replacement dowels for measuring fuel temperature and moisture?

   • the CS506-L Fuel Moisture Sensor uses a 26601 10-Hour Fuel Moisture Stick.
   • the 107 Temperature Probe uses a CS205 10-Hour Fuel Temperature Stick.

   both of these dowels can be easily replaced in the field with a Phillips screwdriver and an adjustable wrench.

2. Where is there a picture with part numbers for the fuel moisture sensor, fuel temperature stick, temperature probe, and mounting stake?

   For descriptions and illustrations (with part numbers) of the various instruments used in measuring fuel temperature and moisture, see the "remote Measurements" brochure.

3. 如何校准诸如107、108、109、110PV-L和Blackglobe-L之类的温度传感器？

   When these sensors are purchased, the following calibration services are offered:tEMPCALandtEMPCAL2。

   • 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提供了两点校准和校准证书。两点校准确定在30°C和65°C下的偏移，不确定性为±0.05°C。

   对于这两种服务，如果购买者在购买时要求使用校准，则可以以不同的值进行校准。此外，可以使用返回材料授权（RMA）编号在购买传感器后要求这两种校准服务。要请求RMA号，请参阅repair and Calibrationpage.

4. Where are the available cable termination options listed for a particular sensor?

   Not every sensor has different cable termination 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.

   一个ll 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。

5. What are the different cable length 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：

   • 一个n –LC model has a user-specified cable length for connection to an ET107, CS110, or retired Metdata1.
   • 一个n –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 models terminate with the connector for an ET107 weather station.
   • –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.
6. How often should the fuel temperature and moisture dowels be replaced?

   both the 26601 10-Hour Fuel Moisture Stick (used with the CS506-L) and the CS205 10-Hour Fuel Temperature Stick (used with the 107-L) can be easily replaced in the field with a Phillips screwdriver and an adjustable wrench.

   每年春季应更换销钉；在某些环境中可能需要更频繁的更换。销售销量越湿/干循环，需要更换的频率就越多。

7. For the 107, 108, and 109 temperature sensors/probes, where within the white cylinder is the thermistor actually located?

   the thermistor is located approximately 3 mm (0.125 in.) back from the probe tip.

8. 如何使用107、108或109温度传感器/探针使用坎贝尔科学数据记录仪进行测量？

   传感器/探针由在半桥电路中配置的非线性热敏电阻组成，如产品手册所示：

   • Model 107 Temperature Probe Instruction Manual
   • Model 108 Temperature Probe Instruction Manual
   • 108-LC Temperature Probe for MetData1 Instruction Manual
   • Model 109 Temperature Probe Instruction Manual

   to measure the sensor/probe, the measurement device has to provide a precision excitation voltage (Campbell Scientific data loggers use 2000 mV), measure the voltage across the precision resistor, determine the thermistor resistance (Ohm's law), and convert the resistance to temperature using the Steinhart-Hart equation.

   Steinhart-Hart方程为1/t=一个+bln(R）+C(ln(r））³where:

   • tis the temperature in Kelvin
   • ris the resistance attin ohms
   • 一个, B,andC是Steinhart-hart系数，取决于感兴趣的温度范围，以及热敏电阻的类型和模型

   For the 107-L, 107-LC, 108-L, and 108-LC, the following are the coefficients for the Steinhart-Hart equation:

   • 一个=8.271111E-4
   • b=2.088020E-4
   • C=8.059200E-8

   For the 109-L, the following are the coefficients for the Steinhart-Hart equation:

   • 一个= 1.129241E-3
   • b=2.341077E-4
   • C=8.775468E-8
9. 可以在温度传感器或温度和相对湿度传感器上完成哪种类型的现场检查，以确定其是否在指定精度的范围内或是否需要校准？

   注意校准和现场检查之间的区别。在现场无法进行校准，因为它需要经验丰富的技术人员和专业设备。

   Field checks of measurements can be done to determine if the data make sense with the real-world conditions. Follow these steps to field check a sensor:

   1. Find a second sensor of the same type as the installed sensor whose data is in question. The second sensor will be used as a benchmark sensor and should be known to be accurate or recently calibrated.
   2. 一个t the site, take readings using both sensors under the same conditions. The best practice is to measure both sensors side-by-side at the same time. Note that the sensors will never have the exact same measurement.
   3. Depending on the sensor model, if the difference in the readings of the installed and benchmark sensors is greater than the sum of the accuracies for both sensors, either return the installed sensor to Campbell Scientific for calibration or replace the appropriate chip.
   • the 107, 108, 109, 110PV-L, and BlackGlobe-L temperature sensors can be calibrated.
   • the HC2S3-L and HMP155A-L temperature and relative humidity sensors can be calibrated.
   • the CS215-L has a replaceable chip for temperature and relative humidity.了解更多信息，refer to the “Maintenance and Calibration” section of the CS215说明手册。
   • HMP60-L仅具有相对湿度的可更换芯片。了解更多信息，请参阅HMP60的“维护”部分说明手册。
10. What are the different cable termination options available for Campbell Scientific sensors?

    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.
    • In the –C (–C w/ET/CS110 Connector) option, the cable terminates in a connector that attaches to a CS110 Electric Field Meter or an ET-series weather station.
    • 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。
