Analog thermocouple amplifier board based on the AD849x from Analog Devices (successor of the AD597). This quad-channel thermocouple board converts the very low voltage signal from thermocouples to a highly-linear, 0.005V/°C output with 2.05V offset (0°C = 2.05V output). The output signal range is from 1.2V to 8.8V that covers the entire -260C - 1380 °C operating range of the K-type thermocouple. Simply connect a power supply (5-32V, wide input range) to the board, plug in your thermocouples with the mini thermocouple connectors and connect the outputs to your data acquisition system or even your Arduino!

Applications

• Automotive data acquisition (exhaust, coolant, brakes, etc)
• Industrial instrumentation
• Oven temperature measurements
• Home brew setups
• Other hobby projects
• • 5V power supply allows use with Arduino power supply
  • Output may need to be suppressed to prevent 9.9V open circuit from overvolting ADCs in certain systems

Features

• Measures -260C-1380C (extended range)
• Ttc = ((Vout - 2.05) * 0.005)°C
• Analog output with high cutoff frequency
• Measure rapid changes in temperature, such as exhaust temp during a drag race, that most sensors can't detect
• Supply voltage range: 5 - 32V with full reverse polarity protection
• ± 2°C linearity from -20 - 400°C ( -4 - 752°F) without correction
• ± 16°C linearity from -100 - 1300°C (-148 - 2372°F) without correction
• Correction tables are available, full range accuracy to ± 1°C
Open thermocouple goes to full-scale output (~9.9V)
• Mounting holes for 4-40 sized screws (see Related Products below)
• Screw terminals sized for PH0 phillips screw driver
• Designed, manufactured, tested and shipped from the USA
