Abstract: A sensor assembly senses hydrogen and moisture content of insulation liquid of a liquid-filled electrical equipment. The sensor assembly includes a radiation source for emitting electromagnetic radiation, a water detection section for receiving a water-containing component of the liquid when the assembly is in operational connection with the electrical equipment and for being illuminated by electromagnetic radiation from the radiation source, a first detector for detecting electromagnetic radiation from the water detection section at a wavelength indicative of an amount of water present at the water detection section, a hydrogen detection section for receiving a hydrogen-containing component of the liquid when the assembly is in operational connection with the electrical equipment and for being illuminated by electromagnetic radiation from the radiation source, and a second detector for detecting electromagnetic radiation from the hydrogen detection section at a wavelength indicative of an amount of hydrogen present at the hydrogen detection section.

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.
