Sensor paper reveals heat distribution

A Sensor Products product story

Thermex is a novel temperature indicating sensor paper that can be used to reveal temperature distribution between any two heated contacting surfaces.

Thermex is a novel temperature indicating sensor paper (TISP) that can be used to reveal temperature distribution between any two heated contacting surfaces.

Thermex is a valuable aid in R and D and QC/QA for assessing heat distribution between heat sealing bars, welding heads, clutch and brake assemblies, as well as other industrial applications where heat analysis is important.

In general, any application requiring a visual analysis of temperature between two surfaces can benefit from the capabilities of the TISP.

"Thermex temperature sensor comes in the form of a large thin sheet", comments Sr Technical Engineer Jeffrey Stark.

"When placed between heated contacting surfaces, the sensor instantly and permanently turns varying intensities between light blue to black", Stark continued, "revealing minute variations in temperature.

Response time is 0.1s or less, with heat sensing ranges from 93 to 149C".

Thermex is a nondestructive (NDT) concept revealing accurate temperature distribution measurement with a relatively minor investment.

Given its thin profile, Thermex is ideal for invasive intolerant environments that cannot accommodate traditional heat or temperature indicators.

The TISF can easily be trimmed with scissors to accommodate smaller application surfaces, and is available in 17 x 14in sheets in packs of 25.
