Fast Response Temp Probes

ATC Semitec is the key UK & Irish distributor  for the extensive range of platinum RTD sensor elements from YAGEO Nexensos GmbH, from Pt100 to Pt2000.

Based in Hanau (near Frankfurt), Heraeus invented the very first platinum sensor in the early 1900s, initially developing wire-wound technology and then later introducing thin film Pt100 elements in the 1970s.

These thin film platinum elements could be readily mass produced which helped to lower the unit cost.  This meant that platinum sensors found their way into a wider range of applications that benefited from their linearity, precision and very stable characteristics.  These applications vary from e-vehicle battery sensors and 3D printer heads to aspirating smoke detectors and e-cigarettes.  YAGEO are constantly striving to develop their sensors for new and exciting applications and still lead the world today in thin film platinum sensor technology.

Temperature sensors come in all shapes and sizes. Our different types vary from  simple plastic encapsulations for air-sensing applications to sophisticated leaf-spring designs, offering precision control of surface temperatures up to 250°C. Fast response temperature sensors utilising exposed bead NTC thermistors or thin wall tubes, help to control rapidly changing temperatures in air or fluids up to 200°C.

Single-insulated 103AT-11 and double-insulated TPE encapsulated temperature probes use 0.5% tolerance NTCs to ensure accurate temperature control to ±0.15K. These thermistor sensors are waterproof to IP68 and are available with or without terminals to suit your application needs. We also supply brass, copper or stainless steel housings (with or without fixings) to provide robust sensors that can be used in numerous environmental conditions.

One of our latest innovations is the F-micro miniature thermistor sensor which was developed for use in medical applications, such as catheters. Utilising smaller and smaller FT thermistors, the F-micro can now be supplied in tubes as small as 0.28mm, with a time constant as fast as 20ms. With further innovation, ever smaller sensors will be available for future applications, allowing very accurate temperature measurement where it wasn’t previously possible.

YAGEO Nexensos not only supply a wide range of platinum RTD elements but also temperature sensor assemblies in various formats.  Of all the numerous sensor designs, two of the most interesting are as follows;

EC3032 temperature sensors are high integrity, encapsulated RTD sensors primarily designed for use in e-vehicle e-motor applications.  Their small size and IP68 insulation rating makes them ideal for use in the e-motor stator windings and they are also impervious to varnish ingress and other fluids such as oil or grease.  Using a Pt1000B element as standard, the 410mm PTFE long leads make this a very versatile sensor that can be used from -50°C to +200°C.

Our PCB RTD temperature sensors are basically chip RTD elements pre-soldered onto printed circuit boards (PCBs) originally designed for use in domestic calorimeters.  The PCB has a meandering, zigzag circuit path to help minimise heat loss from the RTD to improve temperature measurement accuracy.  These RTD PCB sensors are sometimes preferred to NTC versions, as their inherent long-term stability is extremely important when accurately measuring and apportioning consumer energy consumption in district heating systems.
