Senior Applications Engineer J. R. Madden has extensive experience with all things relating to temperature. In this recurring feature, he'll address common customer issues and Moore Industries' solutions.
Q: Do I need to order anything differently if I’m measuring cryogenic temperatures?
A: When measuring temperatures below -10°F, readings are more stable and accurate when a wire-wound RTD element is used. Typical thin-film RTD elements do not perform well at these extreme temperatures.
Q: What about measuring temperatures above 850°F with an RTD? Should I specify a thin-film or wire-wound RTD element?
A: When using RTDs to measure temperatures above 850°F, we recommend using a wire-wound RTD element that is specially built to handle these high temperatures. Many thin-film RTD elements will experience high failure rates at these temperatures.
If you require an RTD sensor for these temperature extremes, order a wire-wound (-WW option) element to ensure the best sensor performance and longevity.
