This British Standard describes a dimensioning system for, and specifies dimensional requirements of, screwed and flanged thermometer pockets so as to ensure both interchangeability between temperature detecting elements of the same nominal dimensions and a proper fit of such elements into the corresponding pockets. Dimensions which are not required to ensure such interchangeability and fit are not mandatory. A recommended design suitable for applications of moderate severity is illustrated. The pocket itself can be regarded as an integral part of the plant and since it should be designed so as to conform to the more usual methods of fixing employed in machinery and process plant, the means of attachment recommended in this standard are in inch units.
It should be noted that the inclusion of a particular size in this standard does not imply that it is suitable for use with all types of detecting element. The availability of sizes and limitations on immersion length should be determined by consulting instrument manufacturers.
A pocket material considered suitable for most applications is also recommended.
No recommendations are given regarding sheaths; guidance on this subject will be found in BS 1041*.
