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 growth are mixed and glued at one finish. When the temperature changes, the two metals have completely 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 enlargement is called the passive layer, and the layer with a big coefficient of growth is recognized as the lively layer. It can immediately measure the temperature of liquid, steam and gas media in the vary of -80℃~+500℃ in varied 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 components. It is very adaptable to different measurement environments.
Diverse construction, can meet different measurement requirements. Can be used as electrical contact bimetal thermometer, explosion-proof electrical contact bimetal thermometer, distant transmission bimetal thermometer, etc.
Fast temperature response and high sensitivity. At the identical time, the temperature change is intuitive and can be displayed and recorded on website.
Small measurement, straightforward to use, and powerful reliability of temperature measurement. Dial nominal diameter: 60,100 (4 inches), one hundred fifty elective.
Long service life, can be utilized for long-term temperature detection in chemical manufacturing, secure physical and chemical properties.
Stable anti-corrosion efficiency. Bimetal thermometers in chemical manufacturing often must be used in liquid and fuel environments. Has good corrosion resistance to protect the pipeline. Will not be affected by the measurement conditions and will not produce corrosion issues that have an result on the standard of measurement.
High pressure-bearing capability. Has good pressure-bearing capacity, can be measured underneath different pressure levels, and is very adaptable to the measurement conditions.
High electrical conductivity. Small resistance temperature coefficient, linear relationship between thermal potential and temperature, good linearity.
What is probably 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 form a watery slurry.
Insert the thermometer probe into the container, making sure to not contact the side, and let it sit till the dial stops transferring.
If the thermometer is accurate, the temperature should 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 does not touch the sides or backside of the pot. 3.
The temperature must be 212°F (100°C). Record the distinction and offset the thermometer as needed. Please note that the boiling point of water varies with altitude. Use this handy water boiling point calculator to search out the best temperature on your altitude.
Bimetallic stem thermometer purposes
The bimetal thermometer is a area testing instrument used to measure low and medium temperatures. It can instantly measure the temperature of liquid, steam and fuel media in the range of -80℃~500℃ in varied manufacturing 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 in the range of -80℃~500℃ in numerous manufacturing processes.
Explosion-proof bimetal thermometer can directly measure the presence of explosives corresponding to hydrocarbons at the site. Directly measure the temperature of liquid, steam and gaseous media within the range of -80℃~500℃ in varied manufacturing processes.
Remote bimetal thermometer can instantly learn the location temperature. And the temperature sign could be transmitted to the distant management system.
