适合于严酷条件下的长期配置
概览
CS451是不锈钢压力传感器，用于测量水位。适合于沟渠、水井、水塘、海湾、湖泊、溪流、水箱等环境。CS451同时测量压力和温度，输出方式为SDI-12或RS-232，可以被我们大多数的数据采集器所读取。
CS451替换了CS450变换器。新变换器的通水口与隔膜之间的空档距离更小，在安装时必须排空其中聚集的空气。空档中聚集的空气会使得测量结果漂移，因为空气会慢慢溶解到水中。
优势与特点
- Quality construction to ensure product reliability
- Rugged stainless-steel case protecting the piezoresistive sensor
- Compatible with most Campbell Scientific data loggers
- Fully temperature-compensated
- Low-power sleep state between measurements to reduce power consumption
- Optional weighted nose cone to facilitate submersion
- Optional NPT nose cone to enable usage in closed-pipe applications
- Quick shipment after receipt of order (ARO)

技术说明
CS451的316L不锈钢外壳里含有一个压阻传感器和一个温度传感器，配有结实的Hytrel线缆，即使在严酷条件下也非常柔韧。线缆内合并了一个通风管，用于补偿大气压的波动。通风管的末端连接干燥管，阻止了水汽进入变换器的内腔中。
CS451有几个压力量程选项和两个精度选项（参阅订货信息）。标准精度选项提供了 0° to 60°C温度范围内的 ±0.1% FS TEB，并包括校准认证。TEB为由补偿温度范围内的非线性、滞后性和热效应的组合误差，每ISA S51.1。请注意高精度选项不适用于 0 到 2.9 psig 量程。
Campbell Scientific提供A150干燥箱，让CS451可以连接到一个预接线的机箱（参阅订货信息）。
