CS506为可燃物含水量传感器,用于测量26601 10-小时模拟可燃物含水量木销的含水量。26601模拟了森林地表相似尺寸的断枝的含水量。CS506/26601的组合用于评估森林可燃物火险因子,经常被包含在我们的预接线或定制的气象站中。(照片显示了CS506可燃物含水量传感器安装在26601仿真可燃物含水量木销中。)
CS506报告较小直径(10-小时)的森林可燃物的火险状态,用单位质量的含水量(1%=1 g)来表示。它含有用环氧树脂封装的电子套件,采集时域反射技术(TDR)来检测26601 10-小时 可燃物含水量仿真木销中的含水量。传感器产生 ±0.7-Vdc 的方波,由Campbell Scientific数据采集器的模拟通道或脉冲通道来读取。数据采集器再将频率通过二次校准曲线转换成可燃物含水量百分比。

The CS506 is typically measured alongside the CS205/107, which measures the fuel temperature.
The 26817 Mounting Stake is often used to mount the CS506/26601 with the CS205/107. This stake places the probes twelve inches above the forest floor. Because the probes are mounted parallel to each other, shadowing is minimized. Cable ties are included for securing the cables to the side of the stake.
The CS506 produces a ±0.7-Vdc square-wave frequency that is read using an analog or pulse channel on a Campbell Scientific data logger. The data logger then converts the frequency measurement to percent fuel moisture via a quadratic calibration.

Both of these dowels can be easily replaced in the field with a Phillips screwdriver and an adjustable wrench.
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.
The dowels should be replaced each spring; more frequent replacements may be required in some environments. The more wet/dry cycles the dowels experience, the more frequently they will need to be replaced.
大多数 Campbell Scientific 传感器的型号中都带有 –L,它表示用户指定线缆长度。如果传感器型号名称列有 –LX (这里 “X” 是其它的某个字符), 那么该传感器需要用户指定长度,但线缆尾端会配有用于某个独特系统的特殊快速接头:
如果一个传感器的主型号数字的后面没有被指定 –L 或其它的 –LX 字符,那么该传感器将具有固定的线缆长度。在产品页面订购栏中 (Ordering tab) 的描述字段的末尾,会列出线缆的长度。例如 034B-ET 型号的描述字段含有信息:Met One风传感器适用于ET气象站,67英寸线缆 (Met One Wind Set for ET Station, 67 inch Cable)。产品按固定的线缆长度做尾端处理,默认是尾线方式。
如果线缆尾端配有用于某个独特系统的特殊快速接头,则型号尾部的字符会指定该传感器用于哪一个系统。例如,034B-ET 型号表明该传感器是一个 034B 且用于 ET107 系统。
不是每一种传感器都有不同的线缆尾端选项。通过查找传感器产品页面的订购栏 (Ordering tab) 中的两个位置,可以检查某种特定传感器的可用的线缆尾端选项:
如果传感器以 –ET, –ETM, –LC, –LQ, 或 –QD 等版本的型号供应,那么线缆尾端选项已经反映在该传感器的产品型号中。例如,034B 以 034B-ET, 034B-ETM, 034B-LC, 034B-LQ, 和 034B-QD 等型号供应。
所有其它的线缆尾端选项,如果可用,会列在该传感器产品页面的订购栏 (Ordering tab) 中的线缆尾端选项 (“Cable Termination Options) 区域。例如,034B-L 风速风向传感器具有 –CWS, –PT, 和 –PW 等线缆尾端选项,显示在 034B-L 产品页面的 订购栏 (Ordering tab) 位置。
注: 当更新的产品添加到我们的库存中时,一般来说,我们会在单个传感器的产品型号下面列出多种线缆尾端选项,而不是创建多个产品型号。例如,HC2S3-L 具有 –C 线缆尾端选项用于连接到 CS110,而我们并没有使用 HC2S3-LC 产品型号。
Campbell Scientific 的很多传感器都有可行的不同线缆尾端处理选项,包括以下几种:
注: 线缆尾端选项的可行性因传感器而异。例如,传感器可能会有 无选项、两个选项或几个选项可供选择。如果预期的选项没有列在所指定的传感器中,请联系 Campbell Scientific 的应用工程师寻求帮助。
