What is a bimetallic stemmed thermometer?

Bimetallic stemmed thermometer is an instrument that uses two completely different metals to measure temperature. Two metals with different coefficients of linear enlargement are mixed and glued at one end. When the temperature adjustments, the 2 metals have totally different degrees of thermal growth. 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 known as the passive layer, and the layer with a big coefficient of growth is called the active layer. It can directly measure the temperature of liquid, steam and fuel media in the vary of -80℃~+500℃ in various manufacturing processes.
Benefits of bimetallic stemmed thermometer

The thermal potential just isn’t interfered with. The thermal potential of the bimetal stemmed thermometer just isn’t disturbed by different components. It is highly adaptable to totally different measurement environments.
Diverse construction, can meet 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 could be displayed and recorded on web site.
Small measurement, easy to use, and strong reliability of temperature measurement. Dial nominal diameter: 60,one hundred (4 inches), a hundred and fifty elective.
Long service life, can be used for long-term temperature detection in chemical production, stable physical and chemical properties.
Stable anti-corrosion performance. ไดอะแฟรม in chemical production usually need to be used 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 issues that have an result on the quality of measurement.
High pressure-bearing capacity. Has good pressure-bearing capability, can be measured under completely different stress levels, and is highly adaptable to the measurement circumstances.
pressure gauge octa . Small resistance temperature coefficient, linear relationship between thermal potential and temperature, good linearity.
What is the most correct 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 five minutes to kind a watery slurry.
Insert the thermometer probe into the container, ensuring to not touch the facet, 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, make certain the probe does not contact the edges or bottom of the pot. three.
The temperature ought to 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 handy water boiling level calculator to search out the right temperature on your altitude.
Bimetallic stem thermometer functions

The bimetal thermometer is a area testing instrument used to measure low and medium temperatures. It can directly measure the temperature of liquid, steam and gasoline media within the range of -80℃~500℃ in varied manufacturing processes.
Electric contact bimetal thermometer is used for temperature control and alarm at manufacturing sites.
Directly measure the temperature of liquid, steam and gaseous media within the range of -80℃~500℃ in various manufacturing processes.
