Abstract: Systems and methods for measuring a value of constituents in a mixed constituent gas having at least one broad band absorber constituent therein and at least one lock constituent are provided. The system uses a combination of integrated cavity output spectroscopy and cavity ringdown spectroscopy to determine the measurement values of constituents in a cavity of a spectrometer. Cavity ringdown in the presence of the at least one broadband absorber constituent and a reference concentration value are used to determine the constituent measurement values when the spectral width of the laser tuning range is overlapped by the absorption band of the broad band absorber in the cavity.

Abstract: A method for operating an ore comminution circuit is provided. The method includes obtaining at least one sensor signal related to an ore feed to the comminution circuit; determining a first ore grindability parameter of the ore feed from the at least one sensor signal, using a model; determining a second ore grindability parameter using parameters of the comminution circuit and/or of at least one comminution device in the comminution circuit; and updating the model with the second ore grindability parameter and the at least one sensor signal.

Abstract: A method and device for estimating a density value ρm indicative of a true density ρ or for estimating a viscosity value ηm indicative of a true viscosity η of a fluid is disclosed. For this, a first resonance frequency fR of a first mechanical oscillator in a reference volume and a second resonance frequency fF of a second mechanical oscillator in contact with the fluid are measured. The estimated value ρm or ηm is then derived using these resonance frequencies fR and fF. During this derivation, at least one fluid-temperature- or fluid-pressure-dependent parameter of the fluid is used. Additionally or alternatively, the first (i.e. reference) mechanical oscillator is arranged in contact with a reference fluid. Thus, fundamental errors in the derivation of the estimated value ρm or ηm are reduced and the estimated value becomes more reliable.

Abstract: The application relates to a method for determining a property of a fluid component of a fluid present in a compartment of an electrical apparatus by means of a measurement device arranged outside the compartment and comprising a chamber for receiving a quantity of the fluid from the compartment. Amongst other steps of the method, an optical path in the chamber is illuminated by a light source and a first intensity of light is measured by a light detector. Then fluid is released from the compartment into the chamber and a second intensity (Ix) of light is measured. Based on these measurements the property of the fluid component is determined.
