In summary: There is also the " reciprocal temperature coefficient of resistance" which is denoted by ##\beta##. This one is a little more esoteric, but it's the one that is used in resistivity measurements.

Homework Statement


Hi:

I'm researching for a arduino sensor that measures resistance of a material depending on the temperature. I have also not found the word that describes the characteristic when measuring resistance-depending on temperature.

Homework Equations



1) Is there any type of sensor that measures resistance when the temperature changes?

2) What is the correct term that describes the characteristic when measuring resistance depending on temperature?

The Attempt at a Solution



I have found a sensor that measures temperature depending on the resistance but not one that measures resistance depending on the temperature. For example there is a sensor called resistance thermometer that measures temperature depending on the resistance but not the other way around.

I'm looking for the term that describes the characteristic when measuring resistance dependent on temperature. For example ductility measures the ability of a material to deform under tensile load.

It's called an Ohmmeter. :-)

Hi pointer_physic. Welcome to Physics Forums.

As rude man stated, the type of meter used is generally called an ohmmeter. There are different setups depending upon the nature of the resistance (or resistivity) being measured.

There is what is called The Temperature Coefficient of Resistance, typically denoted by the variable ##\alpha## (which is pretty generically used for temperature coefficients). You can look this up online with a search engine.
 

FAQ: What is the Temperature Coefficient of Resistance in Sensors?

What is a resistance-temperature sensor?

A resistance-temperature sensor, also known as an RTD, is an electronic device that measures temperature by detecting the change in electrical resistance of a metal wire or film as the temperature changes. It is one of the most accurate and reliable types of temperature sensors available.

How does a resistance-temperature sensor work?

A resistance-temperature sensor works by measuring the change in resistance of a metal wire or film as the temperature changes. This is done by passing a small electrical current through the material, and then measuring the voltage drop across it. The change in voltage is directly proportional to the change in temperature.

What are the advantages of using a resistance-temperature sensor?

Resistance-temperature sensors have several advantages, including high accuracy, stability, and reliability. They also have a wide temperature range and can be used in hazardous environments. Additionally, they do not require any calibration and can be easily integrated into electronic systems.

What are the common applications of resistance-temperature sensors?

Resistance-temperature sensors are commonly used in industries such as automotive, aerospace, and manufacturing. They are also used in household appliances, medical devices, and scientific equipment. They can be found in temperature measurement and control systems, as well as in data logging and monitoring systems.

How do I choose the right resistance-temperature sensor for my application?

When choosing a resistance-temperature sensor, you should consider factors such as temperature range, accuracy, response time, and environment. You should also consider the type of output signal (analog or digital) and the compatibility with your electronic system. It is recommended to consult with a sensor specialist to determine the best sensor for your specific application.
