摘要： An instrument for optically measuring at least one property of a test medium, includes a light source for emission of light, a light management unit for guiding the light onto and/or into and through a detection space in the test medium, a light detection unit for detecting a fraction of the light scattered, reflected or transmitted by the test medium, a power management unit, and a data management unit. The instrument further includes or is coupled to a power source via a source wiring. The power management unit distributes energy from the power source via a buffer wiring to the light source, and via a further wiring to the light detection unit and the data management unit. The data management unit exchanges measurement data via signal wiring with the light detection unit with a receiving unit. The instrument is adapted to be operated in a potentially hazardous environment.

摘要： A method and an apparatus for diagnosis of a flowmeter are disclosed. The method includes thermally coupling a first sensor unit of the flowmeter to a fluid and thermally coupling a second sensor unit of the flowmeter to the fluid. The method also includes actively heating or cooling the first sensor unit by applying power to the first sensor unit such that its temperature is different from the temperature of the fluid, and simultaneously actively heating or cooling the second sensor unit by applying power to the second sensor unit such that its temperature is different from the temperature of the fluid, and typically from the temperature of the first sensor. The method can include determining a temperature TM0 of the fluid, and determining at least two independent quantities related to the heat transfer of the sensor units, each of the at least two independent heat transfer related quantities being determined from at least one element selected from the group including TM0, TM1, TM2, PM1, and PM2, and determining a diagnosis result by setting into relation the at least two independent heat transfer related quantities.

摘要： An oxygen concentration measuring device is provided for determining an oxygen concentration of a gas in a sample volume. The device includes an optical device configured for irradiating the sample volume containing oxygen with a first UV radiation intensity, at least one wavelength of which is close to a spectral absorption line of oxygen, a magnetic field generator configured for applying a magnetic field at the sample volume, and a UV light detector configured for measuring a second UV radiation intensity coming from the sample volume. The oxygen concentration in the sample volume is determined on the basis of the applied magnetic field and the measured second UV radiation intensity.
