The protection tube type thermocouple is a conventional thermocouple, whose structure is to protect the element of a thermocouple from the atmosphere of measuring targets. Currently, sheathed type thermocouples are used in most cases; however, for platinum based noble metal thermocouples, the protection tube type is used in most cases since, with the sheath type, manufacturing is difficult and there is a limitation on costs.

Đặt trưng

A thermocouple consists of a thermocouple element, protection tube, terminal box, insulator, necessary mounting bracket, etc. for practicality.

• Thermocouple Elements

The following thermocouple element types exist. The tip of the element is made into a temperature measuring junction by welding.

• Protection Tubes

The protection tube protects a thermocouple element and insulator from the ambient environment, and a mounting bracket and terminal box, etc. are attached to it. Very severe use conditions are applied to the protection tube depending on the places where temperature is measured. Therefore, for the protection tube, materials and forms suitable for use temperature, atmosphere, purposes, etc., need to be selected.

• Terminal Boxes and Terminal Plates

A terminal box connects compensating cables to a thermocouple. We have drip-proof type EL terminal boxes (made of aluminum die-casting) and other types of materials and forms suitable for the purposes of use.

• Insulators

Insulators are used to provide insulation for thermocouple wires and protection tubes and to prevent short-circuits. We use JIS 2 type insulators.

• Mounting Bracket

A mounting bracket is attached to a protection tube to install the thermocouple onto a measuring place.
We have types of thermocouples which are used without protection tubes in addition to those above. Thermocouples optimum for simple measurement are available with only a heat contact attached to the tip of the coated thermocouple wires such as types EXE and EXS thermocouples. Since, especially, type EXS thermocouples are coated with Teflon resin such as FEP, an insulation type is available, formed with the heat contact part made of the same material.
