Flexible temperature sensors
Thin Thermocouples
Overview
Our thin thermocouples were created by combining heat-resistant film with thin films.
They can be customized with different shapes, measurement point locations, and numbers of units, depending on what you want to measure.
Features & Strengths
Point1 Slight thickness achieved by using film as a base material
The thermocouples are formed using 7.5 μm thin films as the base film material. They are ultra thin, measuring a total of 12 μm.
Point2 Made smaller using fine processing technology, they can be used to measure temperatures in narrow or complex areas Measurement capability
They make it possible to measure temperatures in tiny openings, inside machines, or in high pressure environments.
Point3 Flexible layout
They can be designed according to the desired shape of elements, measurement locations, or targets to be measured.
Point4 High response rate
Since they are low in heat capacity, they can respond quickly to changes in temperature.
Applications

Temperature measurement of electronic parts
Measure temperatures, even in tight gaps or intricate spaces

Measure temperature of heated rollers
The temperature of heated rollers can be measured directly when crimped.
Specifications
Manufacturing examples
The thermocouples can be produced with elements shaped as needed, such as multi-point measurement, thermopile, and the target of direct measurement.
