Monitoring device of resin curing process

The presented article introduces a system for resin curing monitoring. The system is based on a combined sensor built on a ceramic substrate containing a heating element for independent surface heating, interdigital electrodes, and a Pt1000 thermistor for precise temperature measurements. The idea of the simple resin curing monitoring device is based on a small amount of tested resin being applied directly to the sensor surface. After the resin has been applied to the surface, a controlled heating process begins together with the measurement of the electrical properties of the resin, usually the impedance. The curing process is thus monitored and graphically plotted on the connected PC.
