Thermocouples measure temperature by creating a voltage proportional to the temperature difference between the hot junction and the reference junction. The voltage generated is then converted to temperature readings based on a known temperature-voltage relationship. Multiple types of thermocouples are available, each with different temperature ranges and accuracies to suit different applications.
No, a laboratory thermometer typically measures temperatures up to around 250-300°C. To measure the temperature of volcanic lava (600-1200°C), specialized high-temperature instruments such as infrared pyrometers or thermocouples are typically used.
That depends on how hot the water is in the cup. Use the thermometer to measure it and see.

Thermocouples that include an alloy of platinum and iridium are often used to measure temperature in a laboratory.
To use a pyrometer, point the device towards the object you want to measure the temperature of, making sure there are no obstructions between them. Activate the pyrometer and let it measure the temperature, ensuring it is in the correct mode for the material being measured. Read and record the temperature displayed on the pyrometer's screen.
We ca use thermometers, thermocouples, resistance thermometers, pyrometers etc.
You can use thermometers, thermocouples, infrared thermometers, and thermal cameras to measure temperature. These instruments can provide accurate readings of temperature in different environments and with varying levels of precision.
a thermistor is a temperature sensitive resistor - to measure temperature you must measure its resistance and convert that resistance to equivalent temperaturea thermocouple is a temperature sensitive voltage source(i.e. battery) - to measure temperature you must measure the voltage across it and a reference thermocouple at a known constant temperature connected in series with it and convert that voltage to equivalent temperatureNote: Thermistors do not require reference thermistors, thermocouples do require reference thermocouples at a known constant temperature. Thermocouples are more linear than thermistors, making them easier to read accurately. Thermocouples are available that are far more sensitive to small changes in temperature than thermistors.
Examples: thrmometers, pyrometres, thermocouples.
Using different types of thermometers, thermocouples, thermal resistances, pyrometers, etc.
A thermometer is used to measure temperature. There are various types of thermometers such as digital thermometers, mercury thermometers, infrared thermometers, and thermocouples.
Thermocouples allow for higher temperature measurement than thermometers. These high temperatures are often found in industrial applications.
Most common use is in Exhaust Gas Temperature probes.
Meteorologists use various tools to measure temperature, with the most common being thermometers, which can be digital or analog. They also utilize electronic sensors, such as thermocouples and resistance temperature detectors, for more precise readings. Additionally, satellite instruments can measure temperatures at different altitudes and across large areas, providing valuable data for weather analysis.
Rotor temperature can be measured using temperature sensors embedded within the rotor itself or by using non-contact infrared thermometers to measure the surface temperature of the rotor. Additionally, thermocouples can be placed near the rotor to indirectly measure its temperature by monitoring the temperature of the surrounding air or components.
A thermometer is most commonly used to measure the temperature of a liquid. Other methods, such as infrared thermometers or thermocouples, can also be used depending on the specific application and characteristics of the liquid.
Temperature during heat treatment is typically measured using thermocouples, pyrometers, or infrared cameras. Thermocouples are the most common method and are placed directly in or near the material being treated to provide real-time temperature readings. Pyrometers measure temperature by detecting the amount of infrared radiation emitted by the material, while infrared cameras provide a visual representation of temperature distribution across the surface of the material.
