PT100 Temperature Sensors

Everything You Need to Know About PT100 Temperature Sensors

Measurement of temperature is considered to be the most vital function in manufacturing and HVAC systems as well as in food production, scientific research, and much more. In various temperature sensors used, the PT100 temperature sensor can be ranked at the top level as being very reliable and accurate for measuring temperatures. When one looks for accuracy and reliability, one has to understand what PT100 sensors are. So here’s everything one needs to know about PT100 temperature sensors.

What is a PT100 Temperature Sensor?

The PT100 is a resistance temperature detector or a type of sensor that indicates by relating the amount of resistance a sensor’s platinum element has toward the temperature change. Here, “PT” stands for platinum, while “100” is the point at which this sensor has its 100-ohm resistance at 0°C.

PT100 sensors are the best in terms of stability, repetition, and accuracy, making them be used in industrial applications, where precise temperature values are needed.

How Does a PT100 Temperature Sensor Work?

PT100 sensors are based on the principle wherein the resistance of platinum increases with temperature. This linear correspondence between resistance and temperature makes it possible to have a high accuracy of measurement over a wide range.

For instance,

  • At 0°C, the resistance of the sensor is 100 ohms.
  • At 100°C, the resistance is about 138.5 ohms.

This relationship is used by the sensor to convert changes in resistance into temperature values that can be shown on a monitor or incorporated into control systems.

Key Features of PT100 Temperature Sensors

  1. High Precision: PT100 sensors offer accurate readings, with variations usually below ±0.1°C.
  2. Broad Temperature Range: They can measure temperatures from -200°C to +850°C, depending on the type.
  3. 3. Ruggedness: The use of platinum and rugged construction ensures durability, even in hostile environments.
  4. Interchangeability: PT100 sensors are available according to international standards, so they can be interchanged from one system to another without problems of calibration.
  5. 5. Linear Output: The linear variation between resistance and temperature ensures easy, consistent, and readable output.
