Industrial temperature monitoring systems typically include thermocouples, RTDs, infrared sensors, and data loggers for precise temperature control and analysis.
Industrial temperature control is critical for manufacturing, chemical processing, power generation, and other sectors. The right systems ensure product quality, safety, and energy efficiency. This guide explores the most effective industrial temperature measurement and control technologies.
Core Industrial Temperature Measurement Systems
Resistance Temperature Detectors (RTDs)
RTDs provide highly accurate temperature readings by measuring electrical resistance changes in pure metals like platinum. They offer:
- Accuracy within ±0.1°C
- Stable, repeatable measurements
- Wide range (-200°C to 850°C)
Common in food processing and pharmaceutical applications where precision is vital.
Thermocouples
These rugged sensors generate voltage from temperature differences between two dissimilar metals. Benefits include:
- Extreme temperature capability (up to 2300°C)
- Fast response time
- Simple, durable construction
Widely used in steel mills, power plants, and industrial heater systems.
Infrared Pyrometers
Non-contact sensors that measure thermal radiation. Ideal for:
- Moving surfaces
- Hazardous environments
- Very high temperatures (up to 3000°C)
Common in glass manufacturing and metal processing.
