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 a thermocouple to a highly-linear, 0.005V/°C output with 0V offset (0°C = 0V output) while removing unwanted, high frequency EMI from the signal. Additionally, the signals are cold-junction compensated on-board, so there is no need for a reference junction temperature measurement. The full-scale output signal range is from 0V to 5.0V that covers a 0°C to 1,000°C operating range, safe for Arduinos and many other types of data acquisition equipment. Simply connect a power supply (4-32V, 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
  • 5V output range can be used with virtually any data acquisition system or 5V Arduino

Features

• Measures 0C-1000C with a 0V-5V output signal
• Ttc = (Vout * 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
• Wide input range without correction
• Correction tables are available, full range accuracy to ± 1°C
• Open thermocouple goes to full-scale output (~5.0V)
• 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
