Thin-film Surface Thermocouple (seal type)

Heatproof Temperature*
NSH / NSMH:200℃

製品特徴

It’s easy to affix. Simply peel off the separator sheet. Because the separator is larger than the sheet body, it’s easy to peel off.

Type
Type K thermocouple
Sheet size: Choose from two sizes of standard and miniature.
Type T thermocouple
Sheet size: Only miniature size is available.
Heatproof Temperature
For general use: Up to 200°C
(The lead wire’s max. operating temperature is 260°C.) The product has almost no outgassing.
Because one end of the coated thermocouple wire with the optimum usable length is set as the hot junction, there’s no need to prepare a lead wire separately.
The coated thermocouple wire, with PFA fluororesin as an insulator, has the heat resistance of 260°C and excellent chemical resistance. The twisted pair structure can also reduce the noise caused by electromagnetic induction.
We can accommodate customer needs in terminal processing with one side exposed, with a thermocouple connector (our Twintor product), and with a Y terminal. Terminal processing that doesn’t insulate the hot junction is also available.

Product cut samples can be provided.

Adhesive Strength

	Initial Value	180℃	200℃
Adhesive Strength (N/10 mm)	5.10	6.54	6.85
Rate of Change (VS Initial Value)	ー	128%	134%
Rate of Change (VS180°C)	ー	ー	105%

* The test was conducted internally using JIS Z 0237 as reference. The sample used was a single tape.
* The initial value was obtained after leaving the sample at room temperature for at least 2 hours after affixation. The heating condition: after applying heat for 1 hour, left at room temperature for 1 hour. The value is the average of n = 3.
* These values are strictly experimental values and not guaranteed values. They vary depending on each user’s purpose and method of use.

Durability Against Repetitive Affixation

* The test method undertaken was as follows: the adhesive strength of the same sample used in the adhesive strength test was measured repeatedly at the cycle of 1 hour of heating at 200°C and 1 hour of cooling. The maximum number of repetitions of this cycle was set to 20 times. The value is the average of n = 3.
* The figure shows the rate of change in the adhesive strength of repeated affixations, showing the transition when the initial value (0th time) was set to 100%.
* These values are strictly experimental values under the test environment and not guaranteed values. They vary depending on each user’s purpose and method of use.
