They are slowly replacing the use of thermocouples in many industrial applications below 600 °C, due to higher accuracy and repeatability.Common RTD sensing elements constructed of platinum copper or nickel have a unique, and repeatable and predictable resistance versus temperature relationship (R vs T) and operating temperature range. The R vs T relationship is defined as the amount of resistance change of the sensor per degree of temperature change.

What is platinum thermometer?
It is a thermometer using the platinum wire as sensor (resistance thermometer); the resistance of the wire is proportional to the temperature. This type of thermometer is used under 600 0C.
Thermometer use to measure temperature above 1250 celsius?
platinum resistance thermometer
How does an aquarium thermometer work?
It depends on what kind you have.
Is resistance to antibiotics permanent?
No, resistance to antibiotics is not permanent. However, once you have a resistance, that antibiotic will no longer work for specific infections.
How does the kink in a mercury or alcohol work in a clinical thermometer?
The kink stops the mercury from falling, giving the user/reader of the thermometer time to read the highest temperature recorded. Shaking the thermometer lets the mercury fall again.

Why platinum is used in platinum resistance thermometer experiment?
Platinum resistance thermometer requires a small current to pass through it to determine its resistance at different temperatures. Platinum has a linear resistance-temperature relationship; we can use this method to find the resistance at different temperatures.
Thermometer use to measure temperature above 1250 celsius?
platinum resistance thermometer
What is the function of compensating leads in the platinum resistance thermometer?
It is used for the compensation of the platinum wire. in direct sense of current.
What is the Physical properties of a resistance thermometer?
What is the physical properties of a resistance thermometer
Who firstly invented resistance thermometer?
Resistance thermometer was invented by Calender-Van Duesen
What are the four kinds of thermomether?
1. Alcohol or spirit thermometer 2. Mercury thermometer 3. Liquid crystal thermometer 4. Quartz thermometer 5. Reversing thermometer 6. Resistance thermometer
What is the temperature that a resistance thermometer works best at?
0 to 100c
How do LCD thermometers work?
The LCD thermometers work much the same way as a bimetallic thermometer, only the circuitry inside the electronic thermometer measures the temperature through resistance. Through expansion, the device will have a higher resistance in higher temperatures, and the computer inside will make note of that. The temperature it derives is then displayed on an LCD screen. Then it works. http://www.dinodirect.com/Components/LCD-Monitor
How can you measure resistance by using resistance thermometer?
You use an ohmeter. It sends current through the wire to determine value.
What are the types of thermometer?
Celsius, Fahrenheit, and Kelvin.
How does an digital thermometre work?
A digital thermometer has a digital controller called a microcontroller inside of it that measure the thermistors teperature by measuring its electric resistance. Then it displays it on a little LCD screen.
