Description

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 either 0V or 1.245V offset (both configurations stocked) while removing unwanted noise from the signal.

Many supply and output configurations are available with this board, though the PCB was designed with Arduino in mind. Specifically, the output header will plug directly into a standard Arduino Uno or Mega, with a pin-for-pin match for power supply, ground and analog outputs. With a 5V Arduino, temperatures from 0°C to 1,000°C are possible with the 0V offset board and -249°C to 750°C with the 1.245V offset board. If using a 3.3V microcontroller (Due, etc), the board must be supplied with no more than 3.3V to avoid damaging the microcontroller.

Temperature measurement range is dependent on the supply voltage. It is possible to supply the board with higher voltages to allow temperature measurement over the entire operating range of the K-Type and J-Type thermocouples, allowing use with more capable data acquisition equipment.

Features

  • Wide temperature range dependent on supply and offset - options to 1,000°C for 5V Arduinos
  • Analog output with high cutoff frequency signal conditioning
  • Ttc = (Vout / 0.005)°C (0V offset version)
  • Ttc = ((Vout – 1.245) / 0.005)°C (1.245V offset)
  • See AD849x datasheet for linearity and correction tables
  • Measure rapid changes in temperature, such as exhaust temp during a drag race, that most sensors can’t detect
  • Analog filtering to remove higher frequency EMI from signal is included in the design (both differential and common mode filtering)
  • Supply voltage range: 3.3V - 10V+
  • Pin compatible with Arduino Uno and Mega
  • Mounting holes for 4-40 sized screws (see Related Products below)
  • Screw terminals sized for PH0 phillips screw driver
  • High tolerance parts or the AD9496/AD8497 are avaliable. Contact Customer Service for more information.
  • Purchase includes one SEN-30103 Quad Channel Thermocouple Amplifier Board with screw-terminal connectors soldered on. A short segment of 0.1" breakaway header is included (minimum 10 pins)
  • Designed, manufactured, tested and shipped from the USA
