I have written about cure monitoring via AvPro’s (Normal, Okla., U.S.) ThermoPulse microwire sensors, which it aims to use in its cure management systems and also about Synthesites’ (Uccle, Belgium) direct current (DC) dielectric sensors for in-situ monitoring and real-time Tg evaluation. In this blog, I will discuss Lambient Technologies (Cambridge, Mass., U.S.) and their history in alternating current (AC) dielectric sensors as well as their latest LT-440 instrument that combines AC and DC dielectric analysis (DEA). “Both technologies have advantages and disadvantages,” says Lambient founder Huan Lee. “Combining AC and DC measurements provides the widest possible number of tools for R&D, quality control and in-situ monitoring during manufacturing.”
