Type R and Type S Thermocouple Standards - Models 5649 and 5650

Product catalog summary

Overview: The document provides detailed specifications and options for Type R and Type S thermocouples, which are made from platinum and platinum-rhodium alloy. These thermocouples are designed to measure temperatures ranging from 0 °C to 1450 °C with high accuracy.

Specifications:

Temperature Range: 0 °C to 1450 °C
Types: Type R (Platinum/13% Rhodium vs. platinum) and Type S (Platinum/10% Rhodium vs. platinum)
Calibration: Optional fixed-point calibration with uncertainties of ±0.15 °C up to 962 °C, increasing linearly to ±2.0 °C at 1450 °C
Sheath Dimensions: Hot junction sheath is 6.35 mm in diameter; reference junction sheath is 4.8 mm in diameter and 210 mm long
Stability: Long-term stability is ±0.5 °C to 1100 °C and ±2.0 °C to 1450 °C; short-term stability is ±0.2 °C to 1100 °C and ±0.6 °C to 1450 °C
Immersion Depth: At least 152 mm recommended
Weight: 1 kg (2 lb)

Models and Options:

Available in two sizes: 508 mm (20 in) and 635 mm (25 in)
Each size can be ordered with or without a reference junction
Termination options include bare wire, generic copper-to-copper TC connector, standard Type R/S TC connector, or INFO-CON for specific models

Calibration and Accuracy: Each probe is sample tested using fixed-point standards to ensure uncertainties less than 0.5 °C up to 1100 °C. For greater accuracy, individual calibration can reduce uncertainties to ±0.15 °C up to 962 °C, ±0.25 °C up to 1100 °C, and increasing linearly to ±2.0 °C at 1450 °C.

Additional Features: The probe assembly can be disassembled for bare-wire calibrations, and a protective case (Model 2609) is included with new models.
