Temperature is an important quality in daily life, science and industry.
When the strip expands, the coil unwinds somewhat, which moves the indicator.
The industrial bulb thermometer consists of a relatively large copper bulb with long capillary tube that can be bent and guided through the innards of an appliance.
At its end it has a tiny pressure sensor (manometer) which operates an electrical switch. These thermo-controllers are extensively used in air conditioners, washing machines and other appliances.
Today there are still two temperature scales in use: Fahrenheit (UK previously and USA still today) and Celsius (the rest of the world).
The Fahrenheit scale has been replaced scientifically by the Celsius scale (called Centigrade in the UK and USA), and later by the Kelvin scale, which has identical one degree steps.
