Specifications
  • Resistance Thermometers (RTD): Available in Pt 100, Pt 500, and Pt 1000 with limit deviations in classes A or B.
  • Accuracy Class: For a 2-wire circuit, only accuracy class B is confirmed.
  • Temperature Range: Class A (-30°C to +300°C, -100°C to +450°C), Class B (-50°C to +500°C, -196°C to +600°C).
  • Connection Types: 2-wire circuit, with options for kink protection.
  • Materials: Stainless steel (1.4571) and other specified materials.
  • Connection Cables: Options include extension cable strand/fiber glass with stainless steel wire armouring, rated for +400°C or +250°C.
Procedures and Standards
  • Temperature Measurement: Utilizes the temperature-dependent characteristics of materials, such as changing electrical resistance and thermoelectric voltage.
  • Resistance Thermometers: Based on the principle that resistance changes with temperature, first suggested by Wilhelm von Siemens in 1861.
  • Thermocouples: Discovered by Seebeck in 1821, they measure temperature differences between two metals.
Response Time
The response time of contact thermometers is affected by heat capacity, thermal conductivity, and the surface-to-volume ratio. The time constant is used to measure the response time, indicating the time taken to reach 63.2% of a temperature change.
Advantages
  • Thermocouples: Offer a larger temperature range, short response time, robustness, and cost-effectiveness.
  • Resistance Thermometers: Provide high accuracy, long-term stability, and resistance to chemical influences.
Basic Values and Tolerances
  • Thermocouples: Various types (K, L, J, U, T, E, N, S, R, B) with specific temperature ranges and tolerances.
  • RTDs: Accuracy classes according to DIN EN 60751:2009-5, with specific limit deviations for Pt 100 thermometers.
Accessories
Includes various thread sizes and types for different applications.
Conclusion
This document provides comprehensive technical data and guidelines for selecting and using resistance thermometers and thermocouples in industrial applications, emphasizing accuracy, response time, and material specifications.
