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.

Sheath thermocouple

Sheath thermocouple

Thermocouple with lead wire

This is a thermocouple with lead wires, so it can be connected directly to a measuring instrument for use. We can manufacture it according to your preferences, with options for sheath outer diameter, sheath length, and lead length, starting from one piece. The lead wire material is either glass wool insulated or vinyl insulated. Sheath thermocouples are commonly used temperature sensors.

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.

Outer diameter of the sheath Φ0.1mm available! Temperature sensor 'Sheath Thermocouple'

Outer diameter of the sheath Φ0.1mm available! Temperature sensor 'Sheath Thermocouple'

This is a thermocouple with thermocouple wires and high-purity insulation densely encapsulated in a metal thin tube. Despite its thin sheath, it can be used at high temperatures!

The "sheath thermocouple" features a structure where the wire and compensation wire are connected within a sleeve, filled with heat-resistant epoxy resin. The outer diameter of the sheath is available from Φ0.1mm to Φ8.0mm. It solves issues that have traditionally been difficult to measure, such as temperature measurement in precision molds, surface and internal temperatures of engines, small areas, narrow spaces, surface temperature and temperature distribution of materials, as well as high-speed responsiveness. 【Features】 ■ Fine tube finish The small outer diameter allows for easy insertion into small temperature measurement objects or narrow spaces. ■ Sensitive to minor temperature changes with quick thermal response. ■ High durability under high temperature and high pressure (350kg/cm²). ■ Minimum bending radius is up to twice the outer diameter of the sheath and can be bent by hand. 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.*
