Ring terminal temperature probe for power inductor hands-on learning kit

04-06-2019 | Variohm | Subs & Systems

Wurth Elektronik chose Variohm EuroSensor’s ETP-RT series ring-terminal mounted NTP temperature sensors, the TI-PMLK BUCK for the Würth Elektronik Edition learning kit, aimed at students as well as designers and developers of power supplies to assist investigation and evaluation of the impact of magnetic components in a buck regulator, particularly inductors and transformers. The series offers the advantage of determining temperature on the TI-PMLK control board where thermal contact can be performed by screw clamping the sensor directly on the board or solely by a conductive adhesive method on the actual inductor under test.


The kit was developed by Würth Elektronik in collaboration between Texas Instruments and Dr Nicola Fermia at the University of Salermo. TI produces its TI-PMLK series of hands-on learning kits as a collection of power management labs and coursework designed to educate students and engineers on electronic theory and well-known topologies used for power supply design.


The series probes are part of a range of component-embedded sensors that are intended to ease installation and give quick and convenient high-precision temperature measurement. The embedded probe range is also provided as hexagonal bolts as well as tubular designs in PTFE, stainless steel or brass. They are all offered as PTC and NTC versions in a broad assortment of standard options to satisfy general industrial or scientific temperature measurement tasks such as power amplifiers, HVAC, medical instruments and more. All variants include IP67 sealed thermistors with encapsulation techniques that produce the best thermal conductivity to assure fast response times. Typical temperature range is -40C to +125C for the NTC (10K3A1B) version and -40C to +250C for the PT version. Custom modifications higher temperature ranges, modified mounting, connection options and customer specified electrical characteristics.
