How do different temperature sensors compare in accuracy?

How do different temperature sensors compare in accuracy?

Different temperature sensors, like thermocouples, RTDs, and thermistors, have varying accuracy levels. Thermocouples are good for high temperatures but less accurate, while RTDs offer better accuracy in a moderate range.

What about their response times?

Response times vary as well. Thermistors typically have the fastest response time, followed by RTDs, while thermocouples can be slower due to their construction.

Which one is best for industrial applications?

For industrial applications, RTDs are often preferred due to their accuracy and stability over a wide temperature range, but thermocouples are also widely used for high-temperature environments.

Are there any cost differences between them?

Yes, generally, thermocouples are the least expensive, followed by thermistors, with RTDs being the most costly due to their complexity and materials.

Can you recommend a specific model?

Sure! For general use, the Omega RTD is a reliable choice, while the Type K thermocouple is great for high temperatures.
