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 different coefficients of linear growth are mixed and fixed at one finish. When the temperature changes, the two metals have different degrees of thermal enlargement. A pointer is driven to deflect to indicate the temperature. This is the bimetal thermometer. Usually, the layer of the bimetal with a small coefficient of enlargement known as the passive layer, and the layer with a large coefficient of enlargement is known as the active layer. It can instantly 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 just isn’t interfered with. The thermal potential of the bimetal stemmed thermometer isn’t disturbed by different factors. It is highly adaptable to completely different measurement environments.
Diverse construction, can meet completely different measurement requirements. Can be used as electrical contact bimetal thermometer, explosion-proof electrical contact bimetal thermometer, distant transmission bimetal thermometer, and so forth.
Fast temperature response and high sensitivity. At the identical time, the temperature change is intuitive and may be displayed and recorded on website.
Small size, straightforward to use, and strong reliability of temperature measurement. Dial nominal diameter: 60,a hundred (4 inches), one hundred fifty elective.
Long service life, can be utilized for long-term temperature detection in chemical manufacturing, steady bodily and chemical properties.
Stable anti-corrosion efficiency. Bimetal thermometers in chemical production usually must be used in liquid and gasoline environments. Has good corrosion resistance to protect the pipeline. Will not be affected by the measurement situations and will not produce corrosion problems that have an effect on the quality of measurement.
High pressure-bearing capability. Has good pressure-bearing capacity, could be measured underneath different pressure ranges, and is extremely adaptable to the measurement circumstances.
High electrical conductivity. Small resistance temperature coefficient, linear relationship between thermal potential and temperature, good linearity.
What is essentially the most accurate way 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 5 minutes to kind a watery slurry.
Insert the thermometer probe into the container, ensuring to not touch the facet, 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 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, make sure the probe does not contact the edges or backside of the pot. three.
The temperature must be 212°F (100°C). Record the difference and offset the thermometer as wanted. Please observe that the boiling level of water varies with altitude. Use this useful water boiling point calculator to search out the right temperature on your altitude.
pressure gauge is a field testing instrument used to measure low and medium temperatures. It can instantly measure the temperature of liquid, steam and gas media in the vary of -80℃~500℃ in various production processes.
Electric contact bimetal thermometer is used for temperature control and alarm at production sites.
Directly measure the temperature of liquid, steam and gaseous media within the range of -80℃~500℃ in numerous production processes.
Explosion-proof bimetal thermometer can directly measure the presence of explosives similar to hydrocarbons on the site. Directly measure the temperature of liquid, steam and gaseous media within the range of -80℃~500℃ in numerous manufacturing processes.
Remote bimetal thermometer can instantly learn the site temperature. And the temperature sign could be transmitted to the distant management system.
