W hen the bulbhen the bulb is exposed to a rise in temperature, the liquid inside the measuring system expand is exposed to a rise in temperature, the liquid inside the measuring system expand proportionately causing corresponding volumetric changes in the bellows. Since one proportionately causing corresponding volumetric changes in the bellows. Since one end of the bellows is anchored it will move linearly in proportion to the measured end of the bellows is anchored it will move linearly in proportion to the measured temperature.
