Patent ID: 10760941

Abstract:
There is disclosed herein a probe comprising a process connection for mounting to a process vessel. A sealed connector is for connection to the measurement instrument and includes an extension sleeve. A return tube extends from the extension sleeve and is secured to the process connection, the return tube has a connector end proximate the sealed connector and a distal end including vent openings below the process connection. A process tube is connected to the distal end of the return tube and extends into the process vessel. A center conductor is coaxial with the return tube and the process tube for conducting the pulses. A target tube is coaxial with and received within the return tube to define a condensation return path therebetween. The target tube extends downward from a near end at the return tube connector end by bottom end to a position below the process connection. The target tube includes apertures at the near end opening into the condensation return path. Steam from the process vessel flows from inside the target tube through the target tube apertures and into the condensation return path whereby the steam condenses and exits via the vent openings into the process vessel.
