RTD to Temperature Calculator

Visit our menu for more articles and information...

Our RTD Calculator is an essential tool for engineers, technicians, and professionals who need to accurately calculate temperature from the measured resistance of an RTD (Resistance Temperature Detector) sensor. This online software supports several types of RTDs, including PT100, PT1000, CU100, and Ni100, and allows you to convert resistance to temperatures expressed in degrees Celsius (°C), Fahrenheit (°F), or Kelvin (K).

Accurate RTD Conversions: Effortless Resistance to Temperature

Do you work with RTD temperature sensors and need a fast and reliable way to convert their values? Interpreting resistance readings from a PT100, PT1000, or other RTD can be a tedious and error-prone process if done manually using tables or complex Callendar-Van Dusen formulas.

Our RTD Calculator is designed to eliminate this complexity, providing an instant and accurate solution for professionals and enthusiasts.

How does this tool help you?

Versatile Bi-Directional Calculation: Unlike basic tools, our calculator allows you to work in both directions. You can convert a resistance measured in Ohms (Ω) to its equivalent temperature (°C, °F, K) and, with just one click, reverse the calculation to find out what your sensor's theoretical resistance should be at a specific temperature.
Support for Common RTDs: Easily select from the most commonly used RTD types in the industry, such as PT100, PT1000, CU100, and Ni100. The tool preloads standard coefficients to streamline your work.
Accuracy and Flexibility: For applications requiring maximum accuracy or the use of non-standard sensors, you can manually enter the alpha coefficient (α) of your specific RTD, ensuring the results are perfectly tailored to your equipment.
Immediate and Clear Results: Forget about spreadsheets and formula searches. Get the conversion you need instantly, with the number of decimal places you choose and in the temperature unit of your choice.

This calculator is an indispensable tool for process engineers, maintenance technicians, instrumentation students, and any electronics hobbyist who requires accurate and reliable temperature measurements. Use it to streamline your workflow and ensure the accuracy of your data.

How to Use:

Select RTD Type: Choose the type of sensor you are using (PT100, PT1000, CU100, or Ni100).
