The market offers a wide range of temperature measurement solutions, including thermocouples, resistance temperature detectors (RTDs), thermistors, infrared thermometers, and semiconductor thermometers.
RVmagnetics provides a customized alternative – a sensor based on magnetic principles, capable of measuring temperature with a sensitivity of 0.01°C (within a narrow range). The potential temperature measurement range varies depending on the application, covering an interval from -273°C up to 200°C, and with heat-resistant equipment, even higher. Special compositions of MicroWires can measure precisely temperatures up to 500°C.
Like other commercial sensors, the sensitivity of a single sensor depends on the temperature range – the smaller the range, the higher the accuracy. A tailor-made sensing solution offers additional benefits, including compact size, extended range, chemical resistance, and mechanically independent measurements.
Since the MicroWire is a passive sensor, it does not require direct wiring. Due to its miniature size, it can be embedded within materials without causing structural flaws, such as fiber delamination in composites. Measurements can still be performed externally when needed. Data acquisition is possible even through metals and, in optimal conditions, at distances of up to 5-6cm. RVmagnetics also offers the MicroWire sensor as a qualitative temperature sensor, providing digital information on whether a predefined temperature threshold has been exceeded, ensuring a reliable and efficient solution for various applications.

Measurement of the MicroWire attached to the plastic bar provides the temperature of its surrounding, which is room (ambient) temperature. As the finger is placed on the plastic bar, the temperature of the finger transfers heat to the bar, which is quickly detected by the MicroWire.
Conclusion:
It is possible to develop a highly accurate temperature sensor with a customized, miniature hardware solution tailored to the client's requirements. Additionally, a heat distribution map can be created, enabling the monitoring of cooling and heating in specific areas of different materials. Given the vast and unique possibilities for each client, it is essential to present the system's fundamentals, which we showcase in the video.
