BS 3693 is an international standard that discusses the design of scales and indexes on analogue indicating instruments.
BS 3693 gives recommendations for the design of scales and indexes of analogue indicating instruments in which an index moves in relation to a fixed array of scale marks to display the value of a measured quantity, or in which the scale moves in relation to a fixed index.
BS 3693 gives basic designs for scales for single, dual, and multi-range fixed or portable instruments.
BS 3693 is applied in the design of both linear and non-linear scales. BS 3693 is also applied to non-electrical instruments.
Note: BS 3693 gives no recommendations for the design of scales displayed on cathode ray tubes.
BS 3693 on analogue indicating instruments is relevant to:
Analogue indicating instruments are those instruments that indicate the magnitude of a quantity being measured.
BS 3693 assists with the scale, which is the ordered set of scale marks, together with any associated numbering, forming part of an indicating device. BS 3693 also assists with an index which is the fixed or movable part of an indicating device whose position with reference to scale marks enables an indicated value to be determined.
BS 3693 is applicable to scales with:
BS 3693 describes the factors influencing scale design and the method of design of scales. This helps in determining the scale length and reading distance of analogue indicating instruments.
Overall, BS 3693 is useful as it aids the design of scales and indexes on analogue indicating instruments that can be beneficial for your business and can also help you to expand your business globally.
