What is a bimetallic stemmed thermometer?
Bimetallic stemmed thermometer is an instrument that makes use of two completely different metals to measure temperature. Two metals with different coefficients of linear enlargement are mixed and stuck at one finish. When the temperature adjustments, the 2 metals have different levels of thermal enlargement. 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 growth known as the passive layer, and the layer with a big coefficient of enlargement known as the active layer. It can directly measure the temperature of liquid, steam and gasoline media in the range of -80℃~+500℃ in varied production processes.
Benefits of bimetallic stemmed thermometer
The thermal potential just isn’t interfered with. The thermal potential of the bimetal stemmed thermometer is not disturbed by different elements. It is highly 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 excessive sensitivity. At the identical time, the temperature change is intuitive and could be displayed and recorded on website.
Small size, simple to use, and robust reliability of temperature measurement. Dial nominal diameter: 60,100 (4 inches), 150 optional.
Long service life, can be used for long-term temperature detection in chemical production, steady physical and chemical properties.
Stable anti-corrosion efficiency. Bimetal thermometers in chemical production usually 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 issues that have an effect on the quality of measurement.
High pressure-bearing capacity. Has good pressure-bearing capacity, can be measured beneath completely different strain ranges, and is highly 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 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 four to 5 minutes to form a watery slurry.
Insert the thermometer probe into the container, making sure not to touch the aspect, and let it sit till 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 clean container of distilled water to a boil.
Once the water is boiling, insert the thermometer probe. Again, make certain the probe doesn’t touch the edges or backside of the pot. three.
The temperature should be 212°F (100°C). Record the distinction and offset the thermometer as needed. Please notice that the boiling level of water varies with altitude. Use this handy water boiling point calculator to find the proper temperature for your altitude.
