Embodiments relate generally to systems and methods for providing a seal between an expansion plug and an opening in a load pin. A load pin may comprise a strain gauge located within an opening in a body of the load pin; an expansion plug configured to seal with the opening, covering the strain gauge; and a sealing material attached to at least a portion of the expansion plug configured to seal between the expansion plug and the opening. A method may comprise selecting a sealing material configured to prevent damage to the expansion plug from the external environment, based on the environment in which the expansion plug will be used; applying the sealing material to at least a portion of the expansion plug; vulcanizing the sealing material to the expansion plug to combine the two elements; and inserting the expansion plug into the opening.

A pressure sensor for measuring gage pressure in relatively high temperature environments is provided. The sensor includes a housing that is configured to couple to a source of pressurized fluid and has an inner surface that defines a inner volume. A pressure sensitive device is coupled to the sensor housing and is configured define a reference chamber in at least a portion of the inner volume. The reference chamber is fluidly isolated from the source of pressurized fluid. An atmospheric reference port is formed in the sensor housing and is in fluid communication with the reference chamber for maintaining the reference chamber at ambient atmospheric pressure. A porous metallic plug is disposed within the atmospheric reference pressure port.

High temperature gage pressure sensor

An active temperature differential compensation for strain gage based sensors. An array of temperature sensors can be placed at the gage locations to measure the difference in temperature that induces strain on the strain gages. The output of the temperature sensor network can be placed in series with the strain gage network to directly compensate the induced voltage caused by the temperature gradient and/or employed as the input of a mathematical algorithm that can compensate the output from the strain gage bridge to dynamically correct unwanted thermally induced strain in the strain gages.
