Thermocouple temperature measurement system with cold junction compensation 2013-11-20

Thermocouple measurement with amp controlled Cold Junction Compensation

  1. A.V.Ramani
    Quote:
    The circuit shown in Figure 1 is a complete thermocouple signal
    conditioning circuit with cold junction compensation followed
    by a 16-bit sigma-delta (Σ-Δ) analog-to-digital converter (ADC).
    The AD8495 thermocouple amplifier provides a simple, low cost
    solution for measuring K type thermocouple temperatures,
    including cold junction compensation.
