ATS: the heating, sensing and controlling suite of tomorrow
In the past, thermal systems always had trade-offs that often made the “ideal” system out of reach. Whether budgetary concerns limit the number of temperature sensors, tight space requirements restrict the number of zones or the technology hampers how precise the heating systems are, these systems are often curated with compromise. Here, Sean Wilkinson, Product Manager at industrial technology company Watlow, explores how adaptive thermal systems (ATS) are designed to provide companies with the tools to build the heating systems they need, without forcing compromise. A great heating system needs a great controller. Of course, better controllers are only worth the investment if it’s possible to achieve better control throughout the system. Improved control requires more sensors, which can be a costly proposition.
But there are ways to get around high costs. High temperature coefficient resistance (TCR) materials respond to temperature changes with a change in resistance. By measuring that change, it’s possible to determine the temperature at that location. Building heaters out of high TCR materials adds a sensing capability, adding measurements to places where they were previously impossible due to space or cost requirements. Likewise, integrated thermocouple heater (TCH) junction temperature control turns heater power leads into a thermocouple junction. The voltage at this junction varies consistently with the surrounding temperature, so measuring it provides a spot measurement of the temperature at that location. Together, these two technologies offer expanded sensing options without additional wiring or extra controllers.
Multi-loop control and sensing Adopting high TCR materials or TCH junction temperature control can lead to an abundance of available data, which can be used to fine-tune processes and operating costs. However, in other systems, the increased capabilities would lead to an exponential increase in necessary wiring, which may not be possible due to space or budgetary requirements. Watlow, which manufactures industrial heating technology, has decades of experience with thermal systems to help engineers and designers to incorporate ATS technology into a variety of industrial processes and products. Watlow’s multi-loop control uses a multiplex wiring scheme that enables as many as ten times the number of zones per wire when combined with high TCR materials. Increasing zone density allows for unparalleled sensing and control without creating budgetary issues. Additionally, the company developed a standardised harness for the ATS system, which reduces the complexity of installations and the number of design passes needed before installation can begin.
The power of modularity ATS’ true power comes from the fact that each system component is beneficial on its own, but together, they can transform a heating process from end to end. Whether designing a system from scratch or redesigning one that has not quite lived up to expectations, ATS brings something new to the table. Many thermal system design projects reinvent the wheel at each stage of the process. ATS’s modular
“off-the-shelf” approach to many components not only lowers cost, but also reduces the number of design iterations needed before implementation to reduce lead time. However, it is essential to remember that ATS is still customised to the exact needs of each application. Due to that, it represents the best of both worlds. A system that can deliver the accurate temperature control needed for modern manufacturing while avoiding compromises related to cost, space, sensor density and heating control accuracy that other systems face. ATS is a suite of solutions that can be tailored to specific engineering challenges, and without compromise as previously experienced. Now, ATS’s controllers, heating elements and sensors can help companies achieve breakthroughs in cost, efficiency, precision and data production, which can be used to help drive the next generation of growth within various manufacturing applications.

Top-hat rails in accordance with the DIN EN 60715 standard have long been established on the market. They serve as a universal type of mounting for electrical equipment, for example in control cabinets in areas such as automation, control and measurement technology. Especially for such applications, Fischer Elektronik has expanded its existing RKL ... case back panel series by 24 designs for mounting 37 additional case sizes.
The stable rear panels which have a specially developed contour, ensure quick and simple mounting of a case to the top-hat rail. A pressed-in wire form spring made of stainless steel ensures a secure and firm hold. By means of this integrated top-hat rail fastening the case can be placed directly on the top-hat rail making mounting uncomplicated.
Customers can choose between the surface finishes natural colour anodised (ME), black anodised (SA) or electrically conductive transparent passivated (TP). Other surface finishes are available on request.
In addition to surface coating, the core competencies of Fischer Elektronik also include mechanical machinings, so that further processing, such as the insertion of milling pockets and hole patterns or the pressing in of several wire form springs to increase the holding force can be realised according to customer-specific specifications.

Ultra-thin, Flexible Thermistor for fast surface temperature sensing especially in tight spots
Truly versatile the Semitec JT ultra-thin NTC Thermistor is widely used across the world in
many diverse industries from wearable medical technologies (including blood glucose monitors), heat detectors, CPU/IC monitoring, prismatic and pouch cells, and E-V applications. Slim but strong, the JT thermistor is only 0.5mm thick at its sensing tip (thinner than a credit card) making it the thinnest flexible NTC available world-wide.
Suitable for both air and surface temperature monitoring- the sensing element is protected/laminated between two polymer layers making it flexible and resilient at the same time. This flexibility allows the JT’s sensor to be placed much closer to the heat source and often in many space-sensitive applications helping to deliver optimum temperature control. The JT can literally bend over backwards to solve your temperature sensing problems! Also, a high performing NTC - the Semitec JT can operate in extreme temperatures from -50°C to
+125°C with highly accurate 1% R25 tolerances and resistance values of 10kΩ and 100kΩ. In addition, the JT thermistors have excellent electrical insulation and so can be safely used where they might come into contact with adjacent live components Putting it simply, our JT thermistors outperform other slower, larger inflexible competitors! Semitec NTC thermistors form part of an extensive range of thermal components and protection devices available from ATC Semitec.
