گیج دما – Temperature Gauge
Temperature gauges are devices that, depending on environmental conditions and relevant standards, can measure temperature in mechanical installations. Other types of gauges are also used for different purposes, such as measuring mechanical strain. Gauges come in various types, including oil-filled and vacuum, analog and digital, differential and negative pressure, diaphragm, and more.

Liquid-filled thermometer with pressure system indication
This type of thermometer works by using the change in liquid pressure caused by temperature variation, meaning that the temperature change of the thermal sensor causes the pressure of the filled liquid to change, thereby indicating the temperature. The filled liquid can be alcohol, oil, etc.
Thermometer with steam pressure system indication
This type of thermometer contains a volatile liquid inside the thermal sensor, and a
Temperature Gauge Also called a temperature gauge, it is an analog thermometer for a specific point temperature and is functionally divided into the following two categories:
Bimetal Thermometers:
Also known as Other Dial Stem Thermometer . Principle the operation of this thermometer is based on the expansion or contraction of a metal due to temperature changes..The working principle of this thermometer is based on the expansion or contraction of a metal due to temperature changes.
Filled Thermometers (Actuated):
This type of industrial dial thermometer works by using the change in mercury pressure caused by temperature variation, meaning that the temperature change of the thermal sensor causes the pressure of the filled mercury to change, and thus the temperature is displayed by a dial pressure gauge calibrated according to the temperature.
Thermometer with gas pressure system indication
In this type of thermometer, a change in the thermal sensor’s temperature causes a change in the pressure of the filled gas, thereby indicating the temperature. The filled gas must be an inert gas such as nitrogen or helium.
The most important application of filled thermometers is for situations where the temperature probe is more than 1 meter away from the dial indicator. These models are called capillary or stem thermometers, with the stem length ranging from 1 to 5 meters.
