ABSTRACT:
An improved apparatus for measuring the maximum pressure of gas in a system by use of the Brinell principle. In preferred form, the apparatus of the invention is mounted in a plug fitting in the end of a steel cylinder for transporting gases under pressure. The plug has a partial bore extending from the inner end outwardly. A sample is fixed in position adjacent the outer end of the bore. A penetrator is slidably mounted in the bore and has an indentor facing the sample. The penetrator is forced by pressure of the gas against the sample leaving an indentation thereon indicative of the maximum pressure attained in the cylinder over its service life. A vent from the outer end of the plug to the bore prevents buildup of gas pressure between the penetrator and the sample due to leakage of gas along the passage and prevents inaccurate readings.
