You need to tell us what you know so far, in order for us to help you. BTW, homework and coursework questions need to be posted in the Homework Help forums of the PF, not in the general forums like here in the EE forum.

But I can't tell offhand if this is homework or not, so I won't move this thread yet to the Homework Help forums. But either way, you need to tell us what you know and what you've read so far. What does wikipedia.org say, for example? And when you google pt100 platinum wire temperature sensing device, what kind of hits do you get? This hit that I got looks to be helpful:

A Pt100 platinum wire temperature sensing device is a type of temperature sensor that uses a platinum wire as its sensing element. The "Pt100" in the name refers to the resistance value of the platinum wire at 0 degrees Celsius. This type of sensor is commonly used in industrial and scientific applications due to its high accuracy and stability over a wide temperature range.

One of the main characteristics of a Pt100 platinum wire temperature sensing device is its high accuracy. It can measure temperature with an accuracy of 0.1 degrees Celsius, making it suitable for precise temperature control and monitoring.

Another important characteristic is its stability. The platinum wire is highly resistant to corrosion and oxidation, which allows the sensor to maintain its accuracy and performance over time. This makes it a reliable choice for long-term temperature measurements.

Additionally, a Pt100 platinum wire temperature sensing device has a fast response time, meaning it can quickly detect and respond to changes in temperature. This is especially useful in applications where temperature fluctuations need to be closely monitored.

Lastly, this type of sensor has a wide temperature range, typically from -200 to 850 degrees Celsius. This makes it suitable for use in extreme environments and a variety of industries.

In summary, a Pt100 platinum wire temperature sensing device is a highly accurate, stable, and versatile temperature sensor that is commonly used in various industries for its reliable performance.
