What is a bimetallic stemmed thermometer?
Bimetallic stemmed thermometer is an instrument that uses two totally different metals to measure temperature. Two metals with totally different coefficients of linear enlargement are mixed and fixed at one end. When the temperature adjustments, the two metals have completely different degrees of thermal growth. A pointer is driven to deflect to point 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 known as the active layer. It can instantly measure the temperature of liquid, steam and gas media within the vary of -80℃~+500℃ in various manufacturing processes.
Benefits of bimetallic stemmed thermometer
The thermal potential is not interfered with. The thermal potential of the bimetal stemmed thermometer just isn’t disturbed by other elements. It is highly adaptable to totally different measurement environments.
Diverse structure, can meet 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 excessive sensitivity. At the identical time, the temperature change is intuitive and could be displayed and recorded on site.
Small dimension, simple to use, and powerful reliability of temperature measurement. Dial nominal diameter: 60,one hundred (4 inches), a hundred and fifty optional.
Long service life, can be used for long-term temperature detection in chemical production, steady physical and chemical properties.
Stable anti-corrosion performance. Bimetal thermometers in chemical manufacturing typically have to be used in liquid and gas environments. Has good corrosion resistance to protect the pipeline. Will not be affected by the measurement circumstances and gained’t produce corrosion problems that affect the standard of measurement.
High pressure-bearing capability. Has good pressure-bearing capability, can be measured beneath totally different stress levels, 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 probably the most correct 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, ensuring not to 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 wanted.
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 sure the probe does not touch the sides or bottom of the pot. three.
The temperature must be 212°F (100°C). Record the difference and offset the thermometer as needed. Please observe that the boiling level of water varies with altitude. Use this useful water boiling level calculator to search out the best temperature in your altitude.
Bimetallic stem thermometer functions
The bimetal thermometer is a subject testing instrument used to measure low and medium temperatures. It can directly measure the temperature of liquid, steam and gas media in the vary of -80℃~500℃ in numerous production processes.
Electric contact bimetal thermometer is used for temperature control and alarm at manufacturing websites.
Directly measure the temperature of liquid, steam and gaseous media in the vary of -80℃~500℃ in numerous manufacturing processes.
Explosion-proof bimetal thermometer can instantly measure the presence of explosives corresponding to hydrocarbons on the site. Directly measure the temperature of liquid, steam and gaseous media within the range of -80℃~500℃ in various manufacturing processes.
Remote bimetal thermometer can instantly read the positioning temperature. And the temperature sign can be transmitted to the distant control system.
