DESCRIPTIO
The LTK001 is a thermocouple amplifier supplied with a matched cold junction compensator. By separating the amplifier and compensator functions, the problem of compensator temperature rise is virtually eliminated. The compensator is a selected version of the LT®1025 cold junction compensator. The amplifier, which is also available separately as LTKA0x has been specially selected for
thermocouple applications.
