FAQ
- Thermocouples and RTDs do most of the work in industrial measurement - between them they cover 90% of plant temperature loops. Thermistors handle precision low-temperature work. Bimetal thermometers and filled-system dial thermometers (liquid or gas) give you local indication on tanks and pipes with no power required. Infrared cameras and pyrometers handle non-contact work (moving parts, hot surfaces, anywhere you can't put a probe). Fiber optic gets reserved for specialty applications like inside transformers or in strong electromagnetic fields.
- Standard industrial RTDs are accurate to within a few tenths of a degree at 0°C and drift a little wider at higher temperatures. Higher-grade RTDs cut that in half. A Type K thermocouple is good to about 2°C or about three-quarters of a percent of the reading, whichever is worse - Type T is tighter, closer to 1°C. Bimetal dial thermometers run about 1% of full scale, which on a 0-250°F dial is 2.5°F. Match the sensor to what the process actually needs - don't pay for tenths of a degree when the process tolerates degrees.
