Description

This TI Design uses a thermocouple to measure temperatures from -50 °C to 500 °C. The design uses cold junction compensation to reduce errors associated with changes in the cold junction temperature of the thermocouple. The design operates on a single 24 V supply and has a linear output range of 250 mV to 5 V.

Features
  • 24V Single Supply
  • 0 V - 5 V Output
  • Uncalibrated Measured Error of -0.037%
  • Hot Junction Temperatures of -50 °C to 500 °C
  • Cold Junction Temperatures of 0 °C to 75 °C
