Super-Fine Sheathed Thermocouple

Okazaki Manufacturing Company (OMC) has developed the world’s smallest sheathed thermocouple with an outside diameter equivalent to that of a human hair.

The super-fine thermocouple has an outside diameter of just 0.08mm, which means it is ideal for use in applications where space is restricted. The thermocouple can also be bent on installation without causing damage or loss of performance.

Sheathed thermocouples are used in a wide range of temperature sensing applications, including process manufacturing, oil and gas, and petrochemicals.

With a response time of less than 1ms, the thermocouple is suitable for measuring the temperature of any small object or material. An outside diameter of 0.08mm means that the thermocouple element wires need to be extremely fine. In order to form the hot junctions, OMC developed highly advanced manufacturing technology.
