A sensor tube for protecting a sensor inserted into a moving process fluid is provided. The sensor tube includes a process interface section for mounting to a process vessel and an extended section extending from the process interface section to a sealed end. The extended section includes a twisted section having a longitudinal axis. The process interface section and the extended section define a sensor bore configured to receive a sensor therein. The twisted section has a cross section that includes at least three equally sized walls and wherein the walls form helixes along the longitudinal axis of the twisted section.
