Pioneer offers a wide selection of high-precision RTDs (Resistance Temperature Detectors) and thermocouples, the cornerstones of accurate contact temperature measurement. These robust and reliable sensors are used across diverse industries for critical temperature monitoring and control.
RTDs (Resistance Temperature Detectors): Accuracy and Stability
RTDs are known for their excellent accuracy, stability, and linearity. They operate on the principle that the electrical resistance of a metal changes predictably with temperature.
Key Advantages
- High accuracy and repeatability.
- Excellent long-term stability.
- Wide temperature range (depending on type).
- Linear output.
Common Types
- Pt 100 : The most popular RTD, with a resistance of 100 ohms at 0°C.
- Pt 1000 : Offers higher resistance and sensitivity.
Applications
- HVAC/R systems.
- Industrial process control.
- Laboratory and scientific research.
- Food and beverage processing.
- Pharmaceutical manufacturing.
Thermocouples
Thermocouples are rugged and versatile sensors that can measure a very wide range of temperatures. They consist of two dissimilar metal wires joined at one end (the "hot junction").
Key Advantages
- Extremely wide temperature range (depending on type).
- Fast response time.
- Relatively low cost.
- Rugged construction.
Common Types
- Type K (Chromel-Alumel) : The most common type, offering a good balance of temperature range, accuracy, and cost.
- Type J (Iron-Constantan) : Another popular choice, suitable for a variety of applications.
- Type T (Copper-Constantan) : Excellent for low-temperature measurements.
- Type E, N, R, S, B : Other thermocouple types for specialized applications and higher temperature ranges.
Applications
- Furnaces and ovens.
- Exhaust gas temperature measurement.
- Industrial processes with high temperatures.
- Engine testing.
- Plastics and rubber manufacturing.
