Sensor Products Film Grades Temperature Variations
Temperature distribution examples.
Madison, NJ — Since thermal management is critical to heat sink performance, testing with Thermex® temperature distribution film has become a useful design and assembly quality control check. Thermex, from Sensor Products, Inc., is an economical thin sensor film that can be used in virtually any application to test and monitor heated contacting surfaces from 200 to 300°F (93 to 149°C). It can be used alone or in conjunction with Fuji Prescale® pressure indicating film also offered by Sensor Products, Inc.

Upon exposure to heat, Thermex changes color instantaneously and permanently to reveal temperature distribution between any two contacting surfaces. The intensity of this color change directly relates to the temperature it was exposed to enabling the material to reveal spot high or low temperature zones and minute surface variations.

Invasive intolerant environments and interfaces that aren't easily accessed with traditional temperature indicators and infrared thermometers are among candidates for this product.

While the Thermex used for testing may be saved for archival purposes, its low cost renders it inherently disposable. A sheet can be easily trimmed for smaller applications or custom cut to defined dimensions.

New applications are being discovered daily. Common applications include heat sealing, lamination/press, flat web-type machines used in converting, ultrasonic welding, heat sinking, and clutch/brake interfaces.

Post processing analysis of Thermex is available for temperature fluctuations that need to be analyzed with great precision.
