Typical application examples for mineral-insulated thermocouples

Sheath thermocouple with flange

Sheathed thermocouples, also known as sheathed thermocouples, are used in various industries and applications where precise temperature measurements are required. This type of thermocouple consists of two different metallic conductors that are connected together at one end and open at their other end. The open ends are placed at the location where the temperature is to be measured. ThermoExpert° Deutschland GmbH, with its managing directors Heiko Gevert and Andreas Helf, has been a partner of all these industries and of research for many years. The range of applications for thermocouples is almost unlimited - and so is the wealth of ideas for getting customers where they want to go.

When the working atmosphere is right, the economic result is also right.

As simple as the calculation is, as challenging it can be in everyday work to reconcile as many employee concerns as possible with customer projects. But as ThermoExperts, we love challenges and we master them best in conversation. As founders of ThermoExpert Deutschland GmbH, we don't sit in the ivory tower, but are very close to our employees.

ThermoExpert: Fast and reliable

At ThermoExpert, we have always placed great emphasis on being an extremely reliable partner for you. Our internal processes - whether for the production, maintenance or repair of heating solutions or trace heating systems - are extremely carefully timed. If you have a problem and our capacities allow it, we can often implement your wishes on the same day and guarantee reliable dispatch on the following working day. Contact us at any time - the ThermoExperts are always at your side.

Certified quality according to ISO 9001:2015

The ThermoExperts have again received letter and seal for their quality management system - a re-certification without deviations. This clearly shows that the quality standard in the company is supported and lived by all employees. All work processes and procedures have always been continuously checked for their conformity and improvement, because quality assurance has always been part of the guiding principle at ThermoExperten.

Thermal imaging camera detects hot spots and cold spots of the heating application

Whenever high measurement accuracy of the temperature distribution is required, a thermal imaging camera is used - because the development of individual heating applications is often a matter of millimeters and milliseconds. Complementing the FEM analysis, the thermal imaging camera can be used not only to simulate the temperature distribution, but also to map it in real time. The temperature of metal surfaces can thus be measured precisely without contact in the temperature range from 450°C to 1,800°C. The measurement accuracy is ±2 %.

Simulate temperature distribution using FEM analysis

When developing customer-specific heaters, designs can be put through their paces in theory in advance with the help of SolidWorks®. At every stage of development, this allows the temperature distribution on components to be simulated so that the designer can ensure that the desired temperature ranges are also achieved under realistic conditions. Further FEM calculations or strength calculations under the effect of temperature are also possible to ensure product safety.

Flame spraying for fixing heatsealing bands or coating thermocouples

New: The ThermoExperts offer powder flame spraying - also known as metal spraying - as a spray coating process. It is used to attach mineral-insulated heating cable, for example with aluminum or stainless steel, while ensuring heat transfer. The advantage is that, in addition to the material savings, the main focus is on the machine finishing option for creating a completely smooth surface in order to be able to seal the component against a vacuum. But flame spraying is also used to coat thermocouples. In this way, the service life of thermocouples can be extended in aggressive media such as in fluoric acid or sulfuric acid.

The secret of ThermoExperts' success: highly qualified and loyal employees

The company was only founded in 2012. The managing directors then and now are Andreas Helf and Heiko Gevert. Within a very short time, they have written a great success story: They have always been able to meet the steadily growing demand for customized, sheathed thermocouples and mineral insulated heating cable with top quality. Accordingly, the company has grown steadily - to 16 employees in the meantime. The highlight: The employees are loyal and faithful, i.e. the expertise and know-how remain in the company. Specialists are trained internally and further experts for thermal applications can be built up in this way. Thanks to consistent quality at a high level, the market has quickly gained confidence in the still fairly young company. And so, as the successes grow, so do the customer relationships with the absolutely reliable employees.

Trace heating for gas analysis

Customized solutions are the supreme discipline for the thermo experts. Recently, they received an inquiry from a gas manufacturer who needed a precise and constant temperature for its gas analysis. With clear specifications for mass flow and pressure as well as the target temperature, a trace heating system had to be cleverly installed in a plant with very limited space. Thanks to their experience and high-quality materials, the experts mastered this demanding task to the customer's complete satisfaction - because, moreover, the price-performance ratio and the deadlines were right.

Sheath thermocouples with flattened measuring point

Mineral-insulated thermocouples with flattened measuring point (VMA/IMA) are required, for example, for temperature measurement on pumps and housings or on test benches - wherever temperature is to be measured in gaps, on surfaces or at low mounting heights. Typical applications are used in mechanical engineering, in the automotive industry, but also in the research and development departments of universities and institutes.
The tip of the thermocouple with the measuring point is flattened in several manufacturing steps so that the contact surface of the thermocouple is enlarged. This facilitates fixing in the corresponding application or stabilizes the connection with a mechanical component.
