What is a bimetallic stemmed thermometer?
Bimetallic stemmed thermometer is an instrument that uses two different metals to measure temperature. Two metals with totally different coefficients of linear growth are combined and stuck at one finish. When the temperature modifications, the 2 metals have totally different degrees 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 growth is called the passive layer, and the layer with a large coefficient of expansion known as the energetic layer. It can instantly measure the temperature of liquid, steam and fuel media in the range 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 elements. It is highly adaptable to totally different measurement environments.
Diverse structure, can meet completely different measurement necessities. Can be used as electrical contact bimetal thermometer, explosion-proof electric contact bimetal thermometer, remote transmission bimetal thermometer, and so forth.
Fast temperature response and high sensitivity. At the identical time, the temperature change is intuitive and could be displayed and recorded on website.
Small measurement, straightforward to apply, and strong reliability of temperature measurement. Dial nominal diameter: 60,one hundred (4 inches), 150 optional.
Long service life, can be used for long-term temperature detection in chemical manufacturing, steady bodily and chemical properties.
Stable anti-corrosion performance. Bimetal thermometers in chemical manufacturing often must be used in liquid and gasoline environments. Has good corrosion resistance to guard the pipeline. Will not be affected by the measurement conditions and received’t produce corrosion issues that have an result on the quality of measurement.
High pressure-bearing capacity. Has good pressure-bearing capacity, can be measured beneath different pressure 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 essentially the most accurate method 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 4 to five minutes to kind a watery slurry.
Insert the thermometer probe into the container, making sure to not contact 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 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 doesn’t touch the edges or bottom of the pot. 3.
The temperature ought to be 212°F (100°C). Record the distinction and offset the thermometer as wanted. Please note that the boiling point of water varies with altitude. Use this useful water boiling point calculator to search out the best temperature on your altitude.
Bimetallic stem thermometer purposes
The bimetal thermometer is a subject testing instrument used to measure low and medium temperatures. It can instantly measure the temperature of liquid, steam and gasoline media in the vary of -80℃~500℃ in varied manufacturing processes.
Electric contact bimetal thermometer is used for temperature management and alarm at manufacturing sites.
Directly measure the temperature of liquid, steam and gaseous media within the vary of -80℃~500℃ in various production processes.
Explosion-proof bimetal thermometer can directly measure the presence of explosives similar to hydrocarbons on the website. Directly measure the temperature of liquid, steam and gaseous media in the vary of -80℃~500℃ in numerous manufacturing processes.
Remote bimetal thermometer can immediately read the location temperature. And the temperature sign could be transmitted to the remote management system.
