A sensor includes a metal object and a thin film stack formed on at least a part of a surface of the metal object. The thin film stack has an electrically isolating film and a metallic film thereon. A first electrical conductor is defined in the metallic film and is electrically isolated from the metal object and has, in a first end, a connection point connected to a first terminal via a wire and, in a second end, a sensor structure defined in the metallic film. The sensor structure includes a junction of the metallic film penetrating the electrically isolating film to the metal object forming a thermocouple and a metal object terminal connected to a connection point of the metal object via a wire. The connection points of the first electrical conductor and of the metal object are adjacent to and in an isothermal relation with each other.

An input module includes a terminal block and a removable printed circuit board (PCB). The terminal block includes first and second connector assemblies for electrically coupling first and second electrical wires of an external thermocouple to the PCB. At least one of the first or second connector assemblies includes an internal thermocouple. The internal thermocouple has two conductive legs which are formed of different materials and are separated at an end to form a jaw connector for connecting or disconnecting an edge of the printed circuit board to or from the terminal block respectively. The PCB includes a sensor for measuring a temperature on the PCB, and a processing circuit configured to perform cold junction compensation using a cold junction temperature which is determined based on temperature measurement from the sensor and a temperature or voltage measurement from the internal thermocouple, when measuring hot junction temperature of the external thermocouple.

A thermocouple assembly is provided that allows a first type of thermocouple to be used with thermoelements compatible with a second type of thermocouple. For a single thermocouple, a translator device measures a temperature using a new thermocouple and determines and outputs a voltage difference to existing thermoelements for a replaced thermocouple. For two or more thermocouples, a new terminal block is provided between an existing transmitter and the existing thermocouples, which are replaced by new thermocouples of a different type connected to the new terminal block. Existing extension wires are used to make a thermocouple at the new terminal block. A multiplexer is connected to terminals at the existing transmitter or terminal block. Temperatures at the new thermocouples are determined by forming particular circuits and using the temperature at the new block. Additional temperatures can also be determined using existing extension thermoelements. New installation cost can be reduced and functionality can be added using type B, R or S thermocouples with type K or type N extension wire or compensation cable.
