This British Standard relates to thermographs of the bimetallic type, for general and marine use in obtaining a continuous record of air temperatures within the range 0 °F to 140 °F (– 20 °C to 60 °C).
Such an instrument comprises a bimetallic element, the response of which to temperature changes controls the movement of a pen, and a clock-driven drum carrying a chart on which the pen movement records against a temperature scale. A louvred screen may be used to protect the instrument during exposure, but the screen is not included in this British Standard.
If the instrument is to be used in conditions where vibration or violent movement is likely, shock absorbers or some other suitable device may be required to ensure that the specified accuracy is maintained.
