美国Cambridge 粘度探头 321
SPC/L 321内嵌式灌装容器粘度探头
独特的粘度计用于内嵌于灌装容器内混合物和反应监测。
The model SPC/L 321 is an in-line process viscometer that is installed in process fluids to provide continuous temperature and viscosity tracking. Our technology is based on a simple and reliable electromagnetic concept. Two coils move a piston back and forth magnetically at a constant force. Proprietary circuitry analyzes the piston's two-way travel time to measure absolute viscosity.
SPC/L321型探头是一种内嵌式粘度计，这种粘度计可以安装在生产过程中，不间断的检测粘度的温度和粘度。 我们的技术基于简单和稳定的电子式概念。 两组线圈在一个连续电磁力的作用下来回移动一个微型活塞。专利技术的电路分析活塞来回移动行程的时间，从而测量绝对粘度。
A deflector, positioned over the piston, moves fluid into the measurement chamber. This feature, coupled with the constant piston motion, keeps the sample fresh and mechanically scrubs the chamber. A built-in temperature detector (RTD) senses actual temperature in the measurement chamber.
位于活塞上方的导流装置，将液体导入测量室，活塞持续运动以不断更新样品，同时机械摩擦不断擦洗测量室。 一个内置的RTD温度测量探头，实时测量测量室的温度。
The Model SPC/L321 viscometer can be immersed directly into a blend tank or a vessel. The “In-Tank” sensor provides continuous, accurate measurements of mixing and blending viscosities, as well as reaction tracking.
SPC/L321型粘度计能够直接浸入罐内混合物或一个容器内。 这种罐内探头能够对混合物粘度进行连续的，精确的测量，同时对反应进行追踪。
Measurements can be made in 13 different viscosity ranges within an overall span of 0.2 to 20,000 cP or the equivalent cSt. Maximum flow rate over the sensor head is 10 ft/sec (3 m/sec).
能够在0.2-20000CP或等量CST的粘度范围内，进行13种不同粘度发内的测量。 探头头部的最大流速为10英尺/秒（3米/秒）。
*NOTE: ALL ATEX SENSORS ARE SPL ONLY (L = hard wired, C = connector).
说明： 所有ATEX探头都是SPL，L即硬线，C即连接头。
