Abstract: Input terminal of a thermocouple (TC) instrument. The input terminal may include a printed circuit board (PCB), including an input portion configured to receive signals from a thermocouple, and an output portion configured to communicatively connect to the instrument. The input terminal may further include a sensor mounted on the PCB, configured to measure temperature at or near a cold junction of the input terminal. The PCB may include first traces connecting the input portion of the PCB to the output portion of the PCB, and configured to send TC signals to the TC instrument and second traces connecting the sensor to the output portion of the PCB, and configured to send temperature signals to the instrument. The traces may be configured to provide the TC signals and the temperature signals to the TC instrument without using metal pins.
