Standard stainless-steel gauges and pockets are suitable for air, oil, water and other non-erosive fluids. Environmental conditions should be taken into account when considering suitable materials for dial case, etc.

The instrument head should be protected from localised heat or cold sources as this can lead to indicating errors. The function of the gauge does not require any special maintenance procedures but frequent checks must be made to ensure that the instrument is still working correctly and accurately. Any shift in temperature readings greater than twice the tolerance of the instrument must be investigated and the immediate replacement of the gauge if it is faulty.

Advantages of bi-metallic thermometers:

  • Bi-metallic thermometer are easily installed and maintained.
  • Wide temperature ranges are available.
  • The bi-metallic thermometer has class 1 accuracy.

How does a bi-metal thermometer work?

The bi-metal thermometer is made up of two metals moulded together to form a coil. As the temperature changes, the bi-metallic coil contracts or expands, causing the pointer to move up or down the scale.
