What is a bimetallic stemmed thermometer?
Bimetallic stemmed thermometer is an instrument that uses two totally different metals to measure temperature. Two metals with completely different coefficients of linear growth are combined and glued at one end. When the temperature modifications, the two metals have completely different levels of thermal expansion. 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 big coefficient of expansion is known as the energetic layer. It can immediately measure the temperature of liquid, steam and gasoline media within the vary 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 isn’t 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 electric contact bimetal thermometer, remote transmission bimetal thermometer, and so on.
Fast temperature response and high sensitivity. At the same time, the temperature change is intuitive and may be displayed and recorded on site.
Small dimension, easy to use, and strong reliability of temperature measurement. Dial nominal diameter: 60,100 (4 inches), one hundred fifty elective.
Long service life, can be used for long-term temperature detection in chemical manufacturing, secure bodily and chemical properties.
Stable anti-corrosion performance. Bimetal thermometers in chemical production typically must be used in liquid and gas environments. Has good corrosion resistance to protect the pipeline. Will not be affected by the measurement conditions and will not produce corrosion problems that have an effect on the standard of measurement.
High pressure-bearing capability. Has good pressure-bearing capacity, can be measured beneath totally different pressure levels, and is highly adaptable to the measurement circumstances.
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 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 until the dial stops shifting.
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 sure the probe does not contact the perimeters or backside of the pot. three.
The temperature must be 212°F (100°C). Record the difference and offset the thermometer as wanted. Please notice that the boiling level of water varies with altitude. Use this handy water boiling point calculator to search out the proper temperature on your altitude.
digital pressure gauge is a area testing instrument used to measure low and medium temperatures. It can immediately measure the temperature of liquid, steam and gasoline media in the range of -80℃~500℃ in various manufacturing 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 vary of -80℃~500℃ in numerous production processes.
ไดอะแฟรม ซีล -proof bimetal thermometer can directly measure the presence of explosives such as hydrocarbons at the web site. Directly measure the temperature of liquid, steam and gaseous media within the range of -80℃~500℃ in numerous manufacturing processes.
Remote bimetal thermometer can directly learn the location temperature. And the temperature signal could be transmitted to the distant control system.
