We handle "thermocouples with protective tubes," which incorporate thermocouple wires into insulating tubes to protect them from the measuring environment (atmosphere). Depending on the location of use, it is necessary to design and manufacture them with suitable materials, dimensions, and structures. 【Specifications Overview】 ■ Measurable temperature range: -200 to 1,700℃ ■ Measurement temperature tolerance (error range): Maximum ±1.5% of the measurement value or ±2.5℃ (excluding Class 3 of B thermocouples) ■ Types of protective tubes - Non-metallic protective tubes - Metallic protective tubes ■ Thermocouples: B, R, S, N, K, E, J, T *For more details, please download the PDF or feel free to contact us.

Our company manufactures and sells industrial temperature sensors, handling various types of thermocouples. We offer high-performance temperature sensors with unique technologies, such as "protective tube thermocouples," which are insulated with materials like insulating tubes, placed in protective tubes with terminals attached, and "sheath thermocouples," where the space between the metal sheath and the thermocouple wire is tightly filled with high-purity magnesia powder and finished in an airtight state. These products are well-loved by customers both domestically and internationally. 【Product Lineup】 ■ Protective tube thermocouples ■ Sheath thermocouples ■ Coated thermocouples *For more details, please download the PDF or feel free to contact us.

We handle connectors specifically designed for thermocouples. The main body of the connector is color-coded according to the type of thermocouple (excluding high-temperature types), and the type and polarity are indicated by engravings, making it easy to identify. Additionally, by using the included rubber gasket, it can be installed without any play, even with thin wires. Using the optional wire clamp prevents disconnection due to pulling. 【Features】 ■ The connection terminals are made of the same material as the thermocouple or the compensation wire. ■ The sizes of the + and - connection terminals are different, preventing connection errors. ■ The main body of the connector is made of thermosetting resin, providing excellent strength and heat resistance. ■ The continuous use temperature is 205°C for general use (maximum 260°C) and 425°C for high-temperature use (maximum 540°C). ■ Mounting brackets for sheath thermocouples and compensation wires are available as options, etc. *For more details, please download the PDF or feel free to contact us.

At Toyo Thermal Science Co., Ltd., we handle sheath thermocouples with excellent bending characteristics, impact resistance, and corrosion resistance. These thermocouples are tightly filled with high-purity magnesia powder between the metal sheath and the thermocouple wire, finished in an airtight state. Compared to thermocouples with protective tubes, they can have a smaller outer diameter, allowing them to be inserted into small measurement objects. Additionally, they can be bent at a radius of more than five times the sheath's outer diameter, making installation and setup relatively easy. 【Features】 ■ Fast response time ■ Excellent bending characteristics, impact resistance, and corrosion resistance *For more details, please download the PDF or feel free to contact us.
