Self-adhesive surface thermocouple with a lead and open ends
Self-adhesive surface thermocouples with thermal conduction and open ends are used to measure temperature on various surfaces. The surface thermocouples consist of the two legs of a thermocouple, which are embedded in a high-temperature-resistant polyimide laminate at the insulated measurement point. The underside of the backing material is coated with a high-temperature-resistant adhesive. This allows them to be attached anywhere where mounting using screws, clamping rings, or drilling is not possible or not desired.
Their low thermal mass and compact design make them ideal for mounting on flat surfaces or round structures. The advantage is that they are resistant to vibrations and offer good heat transfer, a fast response time, and high measurement accuracy.
Intended use: Primarily in the aerospace industry for variable testing of composite structures and for simulations in space, as well as on test benches, electronic components, or for testing environmental conditions.
Self-adhesive surface thermocouples with wiring and open ends are used for self-assembly of connectors and terminals, as well as for direct wiring to the evaluation unit.
Thanks to the thermal conduit, which is connected via a brass or stainless steel adapter sleeve, even greater distances between the actual temperature measurement point and the data acquisition unit can be bridged.
The thermocouple cable is flexible and, unlike compensation cables, is made of the same material combination as the inner wires of the surface thermocouple. Depending on the sheath insulation, they provide accurate readings in a temperature range up to 300 °C; for glass-silk-insulated thermocouple cables, this range extends to 350 °C.
The transition sleeve, which protects the connection between the surface thermocouple and the thermocouple lead, is encapsulated to be moisture-tight. It also serves as a strain relief for the connected thermocouple inside.
Surface thermocouple in accordance with DIN EN 60584-2, thermocouple (inner conductors) in accordance with IEC EN 60584-1, thermocouple cable in accordance with IEC EN 60584-3.
Operating temperature of the measuring point: -100 to +200 °C
The self-adhesive surface thermocouple has 15 mm of stripped leads.
However, upon request, we can also supply thermocouples with leads of other lengths—please enter the desired length of the leads in the comments field.
The potting compound in the transition sleeve (where the surface thermocouple connects to the thermocouple lead) has a standard continuous temperature resistance of up to 180 °C. However, upon request, a potting compound suitable for continuous use up to 260 °C can also be used— if you would like this change, please let us know in the comments field.

10 Reasons Why We're the Right Choice for Your Project:
If you need even more precision
The highest standard according to DIN EN 60548 is our minimum requirement when it comes to the quality of our sheathed thermocouples. And if your requirements for the precision of our products and solutions are even higher, our value-added services make all the difference.
If the accuracy of the measurement is important, we calibrate our mineral-insulated sheathed thermocouples using the fixed point or comparison method. This allows deviations within the standard to be determined precisely. Especially when several measuring points are present in applications, it can be important to know the exact deviation of the individual thermocouples. Accordingly, we offer factory calibration as well as DAkkS calibration.
X-ray inspection is a non-destructive and highly precise method for examining and verifying the properties and integrity of materials. This imaging technique can be used to identify defects in installed sheathed thermocouples or heating elements. It is also used, for example, to precisely determine the measurement point, ensuring that the sheathed thermocouple can be installed accurately. Upon request, we are happy to provide our thermocouples with X-ray images, including dimensions and labeling.
The helium leak test is primarily used for components that are used for an application or in a production process that takes place in a vacuum or ultra-high vacuum (UHV). In order to avoid pressure loss in the application, we test welds and screw connections on our sheath thermocouples or heating applications in advance. On request, we can also supply vacuum-compatible products, including a test report, which are ready for immediate use on site.
