Insulated thermocouple wire (Teflon, glass, ceramic, enamel)
We offer single wire (single type) and double insulated wire (duplex type).
In a thermocouple, the point where different metals are in contact (the junction) becomes the measurement point. When using uncoated thermocouple wires, it is necessary to devise a way to ensure that each wire does not touch anywhere other than at the measurement point. To alleviate this inconvenience, thermocouple wires that are coated with materials such as Teflon are referred to as insulated thermocouple wires. ■ Insulated single wire for thermocouples (single type) This is a thermocouple wire that has been coated with insulation. It provides ease of handling for thin thermocouple wires and also serves to protect the wire metal, which is susceptible to chemical reactions. Materials available include Formvar (enamel), Teflon (PFA), and Ceramo (ceramic). ■ Double insulated thermocouple wire (duplex type) This consists of two single type insulated thermocouple wires, one for the positive side and one for the negative side, arranged in parallel and further coated to create a two-layer structure, also known as parallel wire. This type is even easier to handle than the single type, and the overall strength of the thermocouple is improved. The junctions are also easier to manufacture.

Applications/Examples of results
■Single Wire Insulated Thermocouple (Single Type) It is mainly used in applications utilizing ultra-fine diameter thermocouple wires, making it possible to measure in areas that are difficult to access with standard thermocouple wires. ■Double Insulated Thermocouple Wire (Duplex Type) Additionally, due to its flexibility and ease of handling compared to insulated tubes or metal sheathed wires, it is supported by many users. We offer a wide range of options depending on the measurement environment and conditions.
