What is a bimetallic stemmed thermometer?
Bimetallic stemmed thermometer is an instrument that uses two totally different metals to measure temperature. Two metals with different coefficients of linear enlargement are combined and glued at one end. When the temperature modifications, the 2 metals have different degrees of thermal expansion. A pointer is pushed to deflect to point the temperature. This is the bimetal thermometer. Usually, the layer of the bimetal with a small coefficient of expansion is known as the passive layer, and the layer with a large coefficient of enlargement known as the active layer. It can immediately measure the temperature of liquid, steam and gasoline media in the vary of -80℃~+500℃ in various production processes.
Benefits of bimetallic stemmed thermometer
The thermal potential isn’t interfered with. The thermal potential of the bimetal stemmed thermometer isn’t disturbed by other elements. It is highly adaptable to totally different measurement environments.
Diverse structure, can meet totally different measurement requirements. Can be used as electric contact bimetal thermometer, explosion-proof electrical contact bimetal thermometer, remote transmission bimetal thermometer, and so on.
Fast temperature response and excessive sensitivity. At the identical time, the temperature change is intuitive and may be displayed and recorded on web site.
Small size, easy to apply, and strong reliability of temperature measurement. Dial nominal diameter: 60,a hundred (4 inches), a hundred and fifty optional.
Long service life, can be used for long-term temperature detection in chemical manufacturing, stable physical and chemical properties.
Stable anti-corrosion efficiency. Bimetal thermometers in chemical production typically have to be utilized in liquid and gasoline environments. Has good corrosion resistance to protect the pipeline. Will not be affected by the measurement situations and gained’t produce corrosion problems that affect the standard of measurement.
High pressure-bearing capacity. Has good pressure-bearing capacity, may be measured beneath totally different strain levels, and is very adaptable to the measurement situations.
High electrical conductivity. Small resistance temperature coefficient, linear relationship between thermal potential and temperature, good linearity.
What is probably the most correct way to calibrate a bimetal thermometer?
Method 1: Ice and water
Fill a container with ice cubes, then add cold distilled water and let it sit for 4 to five minutes to form a watery slurry.
Insert the thermometer probe into the container, ensuring not to contact the aspect, and let it sit until the dial stops moving.
If the thermometer is correct, 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, ensure the probe does not contact the perimeters or backside of the pot. three.
The temperature ought to be 212°F (100°C). Record the distinction and offset the thermometer as needed. Please note that the boiling level of water varies with altitude. Use this useful water boiling point calculator to find the right temperature for your altitude.
