The liquid filled temperature gauges are most often used temperature gauges in industries. In this type liquid is filled in the metal tube. most generally used liquids are mercury and alcohol.

OPERATION PRINCIPLE OF LIQUID FILLED TEMPERATURE GAUGES:
Liquid filled temperature gauges are one of the common temperature measurement techniques  the liquid filled in tube if there is any change in temperature occurred then the level of liquid will be increase or decrease.The tube connected with liquid filled bourdon tube. so, as pressure increase or decrease there will be change in the bourdon tube. As the gauge pressure increases the tube will tend turn coil, while a reduced gauge pressure will cause the tube to coil more tightly.

This motion is transferred through a linkage to a gear train connected to an indicating needle. The needle is presented in front of a card face inscribed with the pressure indications associated with particular needle deflections.The deflection of tube connected with pointer by link.the movement of pointer will indicate the value of temperature This is easy to install.
