技术说明
EnviroSMART探头已经被重命名为EnviroSCAN。
EnviroSCAN探头由Sentek生产，提供了土壤含水量剖面测量，可用于灌溉控制或其它水运移系统中。测量范围从烘干到水饱和。探头在多个深度位置测量土壤含水量，易于安装。由Campbell Scientific提供的安装工具使得安装对土壤扰动最小。
建议EnviroSCAN用于更高精度的研究测量、测量深度大于80 cm，或者是石质土壤。可定制，按用户指定的深度增加测量点的数目。标准配置的最大测量深度为2 m；如果特别供应，也可实现更深深度的测量。

To protect itself, the interface will switch off when the supply voltage is above or below these operating voltages:
- Series 1: 9.6 to 20 Vdc (regulated)
- Series 2: 4.5 to 15 Vdc (regulated)
