What is a bimetallic stemmed thermometer?
Bimetallic stemmed thermometer is an instrument that makes use of two totally different metals to measure temperature. Two metals with completely different coefficients of linear expansion are mixed and stuck at one end. When the temperature adjustments, the 2 metals have totally different degrees of thermal growth. 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 expansion is recognized as the passive layer, and the layer with a big coefficient of enlargement is called the energetic layer. It can immediately measure the temperature of liquid, steam and gasoline 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 is not disturbed by different components. It is very 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 identical time, the temperature change is intuitive and could be displayed and recorded on web site.
Small measurement, simple to apply, and robust reliability of temperature measurement. Dial nominal diameter: 60,a hundred (4 inches), 150 elective.
Long service life, can be used for long-term temperature detection in chemical manufacturing, secure bodily and chemical properties.
Stable anti-corrosion efficiency. Bimetal thermometers in chemical manufacturing typically must be used in liquid and fuel environments. Has good corrosion resistance to guard the pipeline. Will not be affected by the measurement circumstances and gained’t produce corrosion issues that have an result on the standard of measurement.
High pressure-bearing capability. Has good pressure-bearing capacity, may be measured underneath completely different strain levels, and is extremely adaptable to the measurement circumstances.
High electrical conductivity. Small resistance temperature coefficient, linear relationship between thermal potential and temperature, good linearity.
What is the most correct 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 5 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 transferring.
If the thermometer is correct, the temperature should 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, ensure the probe does not touch the sides or bottom of the pot. three.
The temperature must be 212°F (100°C). Record the distinction and offset the thermometer as wanted. Please observe that the boiling point of water varies with altitude. Use this handy water boiling point calculator to seek out the proper temperature for your altitude.
Bimetallic stem thermometer functions
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 within the vary of -80℃~500℃ in numerous production processes.
Electric contact bimetal thermometer is used for temperature control and alarm at production websites.
Directly measure the temperature of liquid, steam and gaseous media in the range of -80℃~500℃ in various manufacturing processes.
Explosion-proof bimetal thermometer can instantly measure the presence of explosives corresponding to hydrocarbons at the web site. Directly measure the temperature of liquid, steam and gaseous media in the range of -80℃~500℃ in numerous production processes.
Remote bimetal thermometer can directly learn the positioning temperature. And pressure gauge 10 bar can be transmitted to the remote control system.
