RHEOLOGICAL MEASUREMENT SYSTEM

Rheological measurement systems for use with systems including pressurized polymer melts and/or other viscous materials are described. In one embodiment, a rheometer is connected to an associated system with a bent, curved, or bendable tube to permit the rheometer to measure rheological properties in locations where the rheometer could not otherwise be located due to the presence of obstructions.Embodiments including rigid straight tubes for connecting a rheometer to an associated system are also described. In another embodiment, a flow-through rheometer is connected to an industry standard 1/2-20 thermowell aperture that is typically used for attaching temperature and pressure probes to a vessel containing a viscous material such as an extruder or injection molding system. 描述了与包括加压聚合物熔体和/或其它粘性材料的系统一起使用的流变测量系统。在一个实施例中，流变仪被连接到具有折弯、弯曲或可弯的管的相关系统，以允许流变仪测量在由于存在障碍物而无法以其它方式定位流变仪到该处的位置的流变性质。还描述了包括用于将流变仪连接到相关系统的刚性直管的实施例。在另一实施例中，流通式流变仪被连接到工业标准1/2-20热电偶套管孔口，其通常用于将温度和压力探针附接到容纳粘性材料的容器，例如挤出机或注塑模制系统。
