监测森林火险因子；适合用于RAWS火险气象站
概览
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。）
优势与特点
- Compatible with most Campbell Scientific data loggers
- Companion product to CS205/107 fuel temperature sensor; can be mounted on the same stake
- Can automatically monitor changing fuel conditions without having to visit the measurement site
- Compatible telemetry options include spread spectrum radios, narrow-band radios, cellular phones, and satellite transmitters

技术说明
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。

Additional Compatibility Information
Fuel Temperature
The CS506 is typically measured alongside the CS205/107, which measures the fuel temperature.
Mounting
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.
Data Logger Considerations
Programming
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 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.
