What is an RTD Sensor? And what are they used for?
RTD stands for Resistance Temperature Detector, so an RTD Sensor is a type of Temperature Sensor. An RTD Sensor contains a resistor which changes resistance value as the temperature changes.
RTD Sensors are more accurate and stable than other temperature sensors such as thermistors or thermocouples. They also have a wider temperature range, approximately -200˚C to 850˚C. This high temperature range means that RTD Sensors are well suited to high temperature industrial processes.
The RTD Sensors constructed of platinum have the highest temperature capabilities but they can also be made from nickel, copper and nickel-iron. They offer high repeatability; this means that they can accurately measure identical temperatures with minimal discrepancies even when exposed to repeated heating and cooling cycles.
RTD Sensors have an immediate response time, less than 0.5 to 5 seconds, making them suitable for industrial applications, HVACR, white goods, automotive and marine.
Here at Variohm we can offer a range of RTD sensors.
