About protective tube thermocouples

Prevent short circuits with insulating tubes! Thermocouples with excellent mechanical strength and chemical/physical properties.

A "protective tube type thermocouple" is a thermocouple that has an insulating tube attached to the thermocouple wire, which is then inserted into a metal or ceramic protective tube, with a terminal box attached. The thermocouple wire is insulated from each other by the insulating tube, preventing short circuits, and because it is housed in the insulating and protective tubes, it has excellent mechanical strength and chemical and physical properties. 【Features (partial)】 <Metal Protective Tube> ■SUS304: Excellent acid and heat resistance, but weak against sulfur and reducing gases ■SUS316: Excellent acid, heat, and alkali resistance, superior corrosion resistance compared to SUS304 <Non-metal Protective Tube> ■Special (PTO): Excellent heat and corrosion resistance, strong against sulfur and reducing gases ■Type 1 (PT1): Good airtightness and heat resistance, strong against molten metals and combustion gases *For more details, please refer to the PDF document or feel free to contact us.

About welded thermocouples

Introduction of a general-purpose "welded thermocouple" aimed at low cost.

The "welded thermocouple" is a general-purpose thermocouple designed primarily for cost-effectiveness, featuring protective tubes (SUS pipes) and mounting accessories (bayonet caps) on glass-covered thermocouple wires. We offer two standard types, K and J, with two standard outer diameters for the protective tube of the insertion part: 4.0mm and 4.8mm. 【Product Lineup】 ■ FK1 Type: Basic welded thermocouple ■ FK2 Type: Welded thermocouple with bayonet cap ■ FK3 Type: Welded thermocouple with bayonet cap ■ FK4 Type: Welded thermocouple with M6/M8 screw ■ FK7 Type: Welded thermocouple with tip band ■ FK8 Type: Welded thermocouple with tip pad *For more details, please refer to the PDF document or feel free to contact us.

About sheath thermocouples

Introducing "sheath thermocouples," which have a faster response time compared to protective tube thermocouples.

A "sheath thermocouple" is a thermocouple wire housed within a thin metal tube (sheath), filled with high-purity inorganic insulating powder (magnesium oxide/MgO) for insulation, and further processed to reduce the outer diameter. This design maintains insulation while also sealing the wire to prevent corrosion and degradation of the thermocouple from air or gases at high temperatures. Since the space between the thermocouple wire and the metal sheath is filled with MgO, it has a monolithic structure, resulting in a faster response time compared to protective tube-type thermocouples. Additionally, the filling material has a high compression density, providing significant mechanical strength, as well as excellent flexibility, airtightness, and corrosion resistance. **Features** - Faster response time compared to protective tube-type thermocouples - High mechanical strength and excellent flexibility - Superior airtightness and corrosion resistance *For more details, please refer to the PDF document or feel free to contact us.*

Fluororesin glasses-type coated thermocouple 'J-SP-FEPF (MGN)'

Introduction of a fluororesin-coated thermocouple in the shape of glasses, suitable for temperature measurement in vacuum environments such as autoclaves.

The "J-SP-FEPF (MGN)" is a fluororesin-coated thermocouple in a glass shape, suitable for temperature measurement in vacuum environments such as autoclaves for molding carbon fiber reinforced plastics. It can maintain pressure because there is no air layer in the insulation even in high vacuum conditions. 【Features】 - Usable in vacuum environments due to the absence of an air layer - Passed pressure tests of 1.45MPa at 200°C and 3MPa at room temperature - Slim profile, ideal for narrow spaces - Easy processing of terminal ends (exposed wire) *Note: The upper pressure limits of the testing equipment are 1.45MPa and 3MPa, so these values are for reference. - Slim profile, ideal for narrow spaces - Can meet the electromotive force ASTM E230 SP grade We also support processes such as thermal contact processing, terminal processing, and connector installation. Please feel free to contact us. *For more details, please refer to the PDF document.
