Abstract: A sensor assembly is disclosed for sensing a status condition of a liquid-filled electrical equipment such as a transformer. The sensor assembly can include a light source; a first hydrogen detection section, the first hydrogen detection section being optically coupled to the light source for receiving light from the light source, wherein the first hydrogen detection section has a first hydrogen sensitive layer that changes an optical response with respect to the received light depending on whether an amount of hydrogen at the first hydrogen sensitive layer is above or below a first threshold; and a first output section optically coupled to the first hydrogen detection section for receiving light having interacted with the first hydrogen sensitive layer such that the received light depends on the optical response of the first hydrogen sensitive layer.

Abstract: A non-contact sensor system and method are disclosed for determining paper sheet quality parameters such as caliper, basis weight and sheet moisture based on THz radiation. The method can include emitting, by an emitter system, a THz radiation signal towards paper sheet material such that the THz radiation interacts with the paper sheet material; detecting, by a detector system, a time and/or frequency dependent response of the THz radiation signal having interacted with the paper sheet material; determining model parameters of a physical model by optimizing the model parameters such that a predicted response of the physical model is fitted to the detected response, the model parameters being indicative of transmission and/or reflection coefficients at interfaces of the paper sheet material with surrounding media; and determining, from the determined model parameters, at least some of the paper sheet quality parameters.
