Interesting Facts about RTD Sensors (Resistance Temperature Detectors)

When a sensor is needed to measure temperature, a common product is an RTD sensor. As you learn more about the different types of sensors in the industry, you will see that there are specific applications for each product. RTD Sensors, also known as Resistance Temperature Detectors, are a great product that can be used in a variety of situations.

Why Choose RTD Sensors?

Resistance Temperature Detectors are the perfect solution if you need something that measures temperature in industrial or laboratory processes. These sensors are built with a “resistor” that adjusts when the temperature changes. The resistor changes the resistance value, measuring the change in temperature to match.

One of the reasons that these sensors are so popular is because of the good reputation that has been built in the industry. RTD Sensors are known as being accurate and stable. Additionally, the manufacturing process can be duplicated if the sensors are needed for a large project.

Are Resistance Temperature Detectors better than Thermocouples?

Thermocouples are another type of popular sensor, but there are some big differences between these products. RTD sensors aren’t necessarily better in all situations. So, the best thing that you can do is talk to our expert team about your individual situation.

Before you choose the sensor that you need, it is important to consider the environment where the temperature sensor will be used. Is it a harsh environment? How high will the temperature go? How important is the accuracy of the sensor for the safety of everyone in the area?

Advantages of RTD Sensors

Here is an outline showing some of the advantages of these sensors. If your situation matches some of these requirements, then this type of sensor might be right for you:

  • Wide Temperature Range: If the sensor needs to measure a wide range of temperatures, then pick the RTD technology. Thin film products can measure between -50 to 500 degrees Celsius. If you need a bigger range, then choose wire-wound RTDs that can measure between -200 to 850 degrees Celsius.
  • Stability: These products are built to last, so they maintain the stability for many years. You can have the peace of mind to know that the sensor will continue working when it is needed.
  • Interchangeability: Do you need to change things out at certain times? Pick products, such as RTD sensors that offer the interchangeability features that you need.
  • Accuracy: When accuracy is important, it is best to choose a product with a proven track record. It has been found that Resistance Temperature Detectors have better accuracy compared with other types of sensors, such as thermocouples.

Since RTDs are durable, and they can handle harsh situations, these products are often selected for industrial environments.
