What is a bimetallic stemmed thermometer?

Bimetallic stemmed thermometer is an instrument that uses two completely different metals to measure temperature. Two metals with completely different coefficients of linear enlargement are mixed and glued at one finish. When the temperature changes, the two metals have different degrees of thermal growth. A pointer is pushed to deflect to point the temperature. This is the bimetal thermometer. Usually, pressure gauge octa of the bimetal with a small coefficient of enlargement is called the passive layer, and the layer with a big coefficient of expansion known as the energetic layer. It can directly measure the temperature of liquid, steam and gas media within the range of -80℃~+500℃ in numerous manufacturing processes.
Benefits of bimetallic stemmed thermometer

The thermal potential isn’t interfered with. The thermal potential of the bimetal stemmed thermometer just isn’t disturbed by different elements. It is highly adaptable to totally different measurement environments.
Diverse structure, can meet completely different measurement necessities. Can be used as electric contact bimetal thermometer, explosion-proof electric contact bimetal thermometer, remote transmission bimetal thermometer, and so forth.
Fast temperature response and high sensitivity. At the same time, the temperature change is intuitive and can be displayed and recorded on web site.

Long service life, can be utilized for long-term temperature detection in chemical manufacturing, steady physical and chemical properties.
Stable anti-corrosion efficiency. Bimetal thermometers in chemical manufacturing usually have to be utilized in liquid and gas environments. Has good corrosion resistance to guard the pipeline. Will not be affected by the measurement situations and gained’t produce corrosion problems that affect the quality of measurement.
High pressure-bearing capacity. Has good pressure-bearing capacity, can be measured beneath totally different stress levels, and is extremely adaptable to the measurement situations.
High electrical conductivity. Small resistance temperature coefficient, linear relationship between thermal potential and temperature, good linearity.
What is essentially the most correct method to calibrate a bimetal thermometer?

Method 1: Ice and water

Fill a container with ice cubes, then add chilly distilled water and let it sit for four to 5 minutes to form a watery slurry.
Insert the thermometer probe into the container, making sure to not touch the aspect, and let it sit till the dial stops shifting.
If the thermometer is accurate, the temperature must be 32°F (0°C) after 30 seconds. If not, recalibrate the thermometer. Record discrepancies and offset thermometers as wanted.
Method 2: Boiling Water

Bring a clear container of distilled water to a boil.
Once the water is boiling, insert the thermometer probe. Again, make sure the probe doesn’t contact the sides or backside of the pot. 3.
The temperature must be 212°F (100°C). Record the distinction and offset the thermometer as wanted. Please notice that the boiling point of water varies with altitude. Use this helpful water boiling level calculator to find the best temperature for your altitude.
