Non-invasive temperature measuring device

A method for assembling an apparatus that measures the temperature of a fluid contained in a passage enclosed by a wall, the method comprising:

• engaging a clamping body to the wall;
• causing a depression in the wall using a protrusion attached to the clamping body that dilates the wall and locates the protrusion in the dilated wall within the passage, wherein the diluted wall is exposed to the temperature of the fluid;
• and
• installing a sensor capsule in the protrusion that measures the temperature of the dilated wall as the temperature of the fluid.

A non-invasive temperature measuring device for measuring the temperature of a fluid in a pipeline passage enclosed by a wall, comprising:

• a clamping body having a probe receptacle extending from a first portion of the clamping body;
• a temperature measuring probe installed in the probe receptacle, the temperature measuring probe including a sensor capsule located in a protrusion, the protrusion extending from the first portion of the clamping body;
• and
• a clamping body second portion rotatably mounted to the first portion,
• wherein the first portion of the clamping body is installed on a wall section of the pipeline after the wall section has been heated and the second portion of the clamping body is rotated to engage the first portion and drive the protrusion to contact the heated wall section and cause the wall section to dilate and locate the protrusion and the dilated wall section in the pipeline passage, wherein the diluted wall is exposed to the temperature of the fluid and the sensor capsule measures the temperature of the dilated wall as the temperature of the fluid.
