What is a bimetallic stemmed thermometer?
Bimetallic stemmed thermometer is an instrument that makes use of two totally different metals to measure temperature. Two metals with completely different coefficients of linear expansion are combined and glued at one end. When the temperature modifications, the 2 metals have totally different levels of thermal expansion. A pointer is pushed to deflect to indicate the temperature. This is the bimetal thermometer. Usually, the layer of the bimetal with a small coefficient of enlargement is recognized as the passive layer, and the layer with a large coefficient of enlargement is called the energetic layer. It can directly measure the temperature of liquid, steam and gasoline media in the vary of -80℃~+500℃ in numerous production processes.
Benefits of bimetallic stemmed thermometer
The thermal potential just isn’t interfered with. The thermal potential of the bimetal stemmed thermometer isn’t disturbed by different elements. It is extremely adaptable to completely different measurement environments.
Diverse construction, can meet completely different measurement requirements. Can be used as electric contact bimetal thermometer, explosion-proof electrical 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 could be displayed and recorded on web site.
Small size, easy to apply, and strong reliability of temperature measurement. Dial nominal diameter: 60,one hundred (4 inches), 150 elective.
Long service life, can be utilized for long-term temperature detection in chemical production, steady bodily 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 guard the pipeline. Will not be affected by the measurement conditions and will not produce corrosion problems that have an effect on the quality of measurement.
High pressure-bearing capability. Has good pressure-bearing capacity, may be measured underneath different stress 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 the most accurate 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 4 to five minutes to kind a watery slurry.
Insert the thermometer probe into the container, making sure not to contact the aspect, and let it sit until the dial stops shifting.
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 needed.
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 edges or backside of the pot. 3.
The temperature must be 212°F (100°C). Record the distinction and offset the thermometer as needed. Please observe that the boiling point of water varies with altitude. Use this helpful water boiling level calculator to find the right temperature on your altitude.
Bimetallic stem thermometer applications
The bimetal thermometer is a subject testing instrument used to measure low and medium temperatures. It can immediately measure the temperature of liquid, steam and gas media within the range of -80℃~500℃ in varied manufacturing processes.
Electric contact bimetal thermometer is used for temperature management and alarm at manufacturing websites.
Directly measure the temperature of liquid, steam and gaseous media within the vary of -80℃~500℃ in numerous manufacturing processes.
Explosion-proof bimetal thermometer can directly measure the presence of explosives such as hydrocarbons on the site. Directly measure the temperature of liquid, steam and gaseous media within the range of -80℃~500℃ in various production processes.
Remote bimetal thermometer can immediately read the site temperature. And the temperature signal could be transmitted to the distant management system.
