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 finish. When the temperature modifications, the 2 metals have completely different levels of thermal enlargement. A pointer is driven to deflect to indicate the temperature. This is the bimetal thermometer. Usually, the layer of the bimetal with a small coefficient of growth is identified as the passive layer, and the layer with a big coefficient of growth is known as the active layer. It can instantly measure the temperature of liquid, steam and fuel media within the vary of -80℃~+500℃ in numerous manufacturing processes.
Benefits of bimetallic stemmed thermometer

Small size, simple to apply, and strong 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 performance. Bimetal thermometers in chemical production typically must be utilized in liquid and gasoline environments. Has good corrosion resistance to guard the pipeline. Will not be affected by the measurement circumstances and will not produce corrosion problems that have an result on the standard of measurement.
High pressure-bearing capacity. Has good pressure-bearing capacity, can be measured beneath different pressure ranges, 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 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 kind a watery slurry.
Insert the thermometer probe into the container, making sure to not touch the facet, and let it sit till 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, make sure the probe does not touch the perimeters or backside of the pot. three.
The temperature should be 212°F (100°C). Record the difference and offset the thermometer as wanted. Please observe that the boiling level of water varies with altitude. Use this handy water boiling level calculator to search out the right temperature on your altitude.
Bimetallic stem thermometer applications
The bimetal thermometer is a area testing instrument used to measure low and medium temperatures. It can directly measure the temperature of liquid, steam and gas media in the range of -80℃~500℃ in various production processes.
Electric contact bimetal thermometer is used for temperature management and alarm at manufacturing websites.
Directly measure http://มือสองออนไลน์.com of liquid, steam and gaseous media within the vary of -80℃~500℃ in varied production processes.
Explosion-proof bimetal thermometer can immediately measure the presence of explosives such as hydrocarbons on the website. Directly measure the temperature of liquid, steam and gaseous media in the range of -80℃~500℃ in varied production processes.
Remote bimetal thermometer can instantly read the positioning temperature. And the temperature signal could be transmitted to the remote control system.
