Sheathed Thermocouple suits space restricted applications.
July 30, 2009 -
Featuring outside diameter of 0.08 mm, Sheathed Thermocouple can be bent on installation without causing damage or loss of performance. Unit comprises metal sheath with thermocouple elements inside that are tightly packed with mineral powder, which insulates thermocouple elements from one another and from sheath. With response time of less than 1 ms, device is suitable for measuring temperature of any small object or material.

Diameter of New Sheathed Thermocouple is Equivalent to a Human Hair
Okazaki Manufacturing Company (OMC), a leading manufacturer of high quality, high accuracy temperature measurement products, including thermowells, mineral-insulated thermocouple and RTD cable, has developed the world's smallest sheathed thermocouple, which has an outside diameter equivalent to that of a human hair.
Launched last month in Japan and now available worldwide, the new super-fine thermocouple has an outside diameter of just 0.08mm, which means it is ideal for use in applications where space is restricted. The thermocouple can also be bent on installation without causing damage or loss of performance.
Sheathed thermocouples are used in a wide range of temperature sensing applications, including process manufacturing, petrochemicals, oil and gas, medical, academic institutions, semiconductor manufacturing, automotive R&D, aerospace and defence.
OMC is a pioneer in temperature measurement technology and product development. Prior to this latest product launch, OMC's previous smallest diameter sheathed thermocouple had an outside diameter of 0.10mm. The smallest outside diameter sheathed thermocouple currently available on the market from an alternative supplier is 0.15mm.
With an incredible response time of less than 1ms, OMC's latest sheathed thermocouple is suitable for measuring the temperature of any small object or material. An outside diameter of 0.08mm means that the thermocouple element wires need to be extremely fine. In order to form the hot junctions, OMC has developed highly advanced manufacturing technology at its plants in Japan.
A sheathed thermocouple typically comprises a metal sheath with thermocouple elements inside that are tightly packed with mineral powder. The mineral powder insulates the thermocouple elements from one another and from the sheath. The smaller the diameter or mass of a sheathed thermocouple, the faster the thermal response time will be.
Chris Chant, Business Development Manager at OMC commented: "We've supplied sheathed thermocouples for all kinds of unusual applications, particularly where space restrictions mean the customer requires a small diameter solution. For example, we recently supplied thermocouples to a defence company, who installed the units in the exhaust manifold of a battle tank. We've also supplied similar units to automotive companies for the temperature profiling of diesel engines and for fuel cell research."

Okazaki Manufacturing Company (OMC) was founded in 1954 and started the design and manufacture of temperature-related products in Kobe, Japan. The company has always been at the forefront of product design and the use of innovative technology. In 1963, OMC developed Resiopak, a metal-sheathed MgO insulated resistance thermometer now used for temperature measurement within the petrochemicals industry globally.
Today, OMC designs and manufactures a wide range of reliable, high quality, high accuracy temperature measurement products. With a turnover in excess of 110 million USD, OMC is one of the largest manufacturers of mineral insulated (MI) thermocouple and RTD cable, which is the first building block of industrial temperature sensors. OMC operates from a series of specialist sales support offices worldwide, backed up by a team of local representative companies all with specialist instrumentation departments. OMC has manufacturing sites in Japan, USA and Taiwan.
All OMC's temperature products can be fully certified for use in potentially explosive atmospheres to International Standards and to country-specific variations. OMC temperature assemblies are certified by FM for NEC (USA) standards, BASEEFA for IECEx Product Approval and for type approval in compliance with EU ATEX directives. Country-specific approvals include GOST K, GOST R, NEPSI (China) and KOSHA (Korea).
