Surface thermocouples

A number of things need to be noted when measuring temperatures on surfaces. To avoid distortion of the measuring result, the entire measuring surface of the thermocouple must have contact with the surface being measured. A low temperature influence by the thermocouple is also important. This can only be achieved by ensuring a low net weight of the thermocouple. On electrically conductive surfaces, it must be borne in mind that currents applied from elsewhere can distort the measuring result. No other electrical equipment should be connected or earthed to the surface. If this cannot be avoided, insulated thermocouples should be chosen. In addition to the temperature range, where the thermocouple can be attached it is also crucial for making the right choice.

We offer thermocouples for every surface, providing easy installation and rapid response times. The type, wire length and connection type can be chosen at will for all surface thermocouples.

1. Designs

With the spring-mounted loop thermocouple, the surface temperature of moving parts, e.g. brake disks, drums or treadmills, can be determined. The measuring point consists of a small metal plate which is seated on a round ceramic housing. A spring which pushes the measuring point with a consistent pressure against the surface is fitted behind the housing.  By attaching the mounting adapter, the spring-mounted sensor is guided onto the surface using a bayonet cap. This ideally compensates movements caused by centrifugal forces and vibrations, as well as the reduction in volume caused by wear, and guarantees a valid measuring result.

We offer a particularly robust version with a surface sensor in the form of a cable lug. The thermocouple’s measuring point is integrated into the stainless steel cable lug, thereby allowing the thermocouple to be screwed onto a surface. The surface temperature can thus be reliably measured at a defined point. Thanks to the preparation for metric thread sizes, the installation location can be quickly changed, facilitating multiple use. Depending on the wire connected, measurement of surface temperatures up to +550 °C is possible.

Unlock Precise Temperature Monitoring with Surface Thermocouples

Surface thermocouples have revolutionized temperature measurement in various industries, offering unparalleled precision and reliability. These ingenious devices consist of two dissimilar metal wires joined at one end, creating a junction that generates a small electrical voltage proportional to the temperature difference between the junction and the reference point. What sets surface thermocouples apart is their ability to measure temperatures directly on the surface of an object, making them invaluable in countless applications.

We’ve seen firsthand how surface thermocouples transform temperature monitoring processes. Their compact design allows for easy installation in tight spaces, while their fast response time ensures real-time data collection. This rapid feedback is crucial in industries where even slight temperature fluctuations can significantly impact product quality or process efficiency.

One of the key advantages of surface thermocouples is their versatility. They can be used on flat or curved surfaces, making them suitable for a wide range of applications. Whether you’re working with metal, plastic, or even glass surfaces, there’s a surface thermocouple designed to meet your specific needs. This adaptability has made them a go-to solution for engineers and technicians across various sectors.

Surface mount thermocouples, a subset of this technology, offer even greater flexibility in installation. These low-profile sensors can be easily attached to surfaces using adhesives or mechanical fasteners, minimizing disruption to the monitored system. This feature is particularly valuable in scenarios where maintaining the integrity of the monitored surface is crucial.

How Surface Mount Thermocouples Revolutionize Industrial Processes

The impact of surface mount thermocouples on industrial processes cannot be overstated. These innovative sensors have transformed how we approach temperature monitoring in manufacturing, processing, and quality control applications. By providing accurate, real-time temperature data, surface mount thermocouples enable precise process control, leading to improved product consistency and reduced waste.

We’ve observed that industries ranging from automotive to aerospace have embraced surface mount thermocouple technology. In automotive manufacturing, for instance, these sensors play a critical role in monitoring the temperature of engine components during testing and operation. This data is essential for optimizing engine performance, improving fuel efficiency, and ensuring compliance with emissions standards.

The food and beverage industry has also benefited significantly from surface mount thermocouples. These sensors are used to monitor the temperature of processing equipment, ensuring that food products are prepared and packaged at the correct temperatures. This not only ensures food safety but also helps maintain consistent product quality, which is crucial for customer satisfaction and brand reputation.

In the electronics industry, surface mount thermocouples have become indispensable for thermal management. As electronic devices become smaller and more powerful, managing heat dissipation becomes increasingly challenging.
