Ichimura Metal Sheath Thermocouple

Ichimura Metal Sheath Thermocouple

Speedy sales, the essence of the latest technology.

The structure of the sheath thermocouple consists of a metallic thin tube (sheath) that is firmly filled with thermocouple wires using high-purity inorganic insulating magnesium oxide (MgO) powder, providing high insulation and high pressure resistance. It has high reliability and maintains functionality even when used in harsh conditions such as corrosive atmospheres, vibrations, and areas with frequent bending.

High-temperature sheath thermocouple "TP"

High-temperature sheath thermocouple "TP"

Outer diameter of the sheath φ3.2 to φ9.5! A sheath thermocouple that demonstrates excellent durability and stability!

The "TP" is a high-temperature sheath thermocouple that demonstrates excellent durability and stability in high-temperature ranges (over 1000°C) compared to conventional Inconel and stainless steel sheath thermocouples. The sheath material is based on a Ni-Cr alloy and also incorporates Fe and AI. It can be used at temperatures up to 1335°C (with sheath outer diameters ranging from φ3.2 to φ9.5). Additionally, it forms an oxide film on the surface of the sheath metal in high-temperature ranges, protecting the thermocouple wire inside and enabling highly accurate temperature measurement. 【Features】 ■ Excellent durability and stability ■ Based on a Ni-Cr alloy with the inclusion of Fe and AI ■ Usable at temperatures up to 1335°C ■ Forms an oxide film on the surface of the sheath metal in high-temperature ranges ■ Protects the thermocouple wire inside, allowing for highly accurate temperature measurement *For more details, please refer to the PDF document or feel free to contact us.

About sheath thermocouples

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 inside 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 due to air or high-temperature gases. Since the space between the thermocouple wire and the metal sheath is filled with MgO, it has a unified 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.*

Nicrobel C thermocouple

Nicrobel C thermocouple

The Φ1.0 thin sheath K thermocouple can measure up to 900°C! It achieves higher stability and environmental resistance compared to conventional Inconel sheath thermocouples.

Conventional metal sheaths (such as stainless steel and Inconel) experience chemical corrosion and metal fatigue at high temperatures, which significantly affect the stability and lifespan of thermocouples. The Nicrobel sheath is a revolutionary metal sheath made from a heat-resistant alloy with a composition very similar to type N thermocouples (NicroSil), minimizing the adverse effects of chemical corrosion and metal fatigue. The diameter of the protective tube can range from Φ1 to Φ8. You can choose from straight or L-shaped designs, as well as options with terminal boxes, depending on your application.

Sheath thermocouple

Sheath thermocouple

The introduction part to devices such as sleeves and lead wires can also be manufactured simultaneously! Thermocouples protected by metal tubes.

The "sheath thermocouple" is a product covered with a protective sheath made of stainless steel or Inconel. Since the space between the thermocouple wire and the sheath is filled with insulation material under high pressure, it can be installed in areas where electrical insulation is required. In addition, we offer a "non-grounded" type that ensures insulation between the sheath and the thermocouple, a "grounded" type where the thermocouple and sheath are welded at the tip for relatively better responsiveness, and an "exposed" type that exposes the temperature measurement contact point from the end of the sheath. 【Features】 ■ Manufactured including the device introduction part ■ Insulation material filled under high pressure between the thermocouple wire and the sheath *For more details, please refer to the PDF document or feel free to contact us.
