摘要： Method for determining the UV transmittance of water in a UV disinfection plant, through which water flows, wherein the UV disinfection plant has a plurality of radiator arrangements, each with a UV radiation source, a sleeve tube which surrounds the UV radiation source and which has an end face at an open end, and with a UV-C sensor which detects the UV radiation emerging from the sleeve tube without the influence of the water, and with at least one further UV sensor which is arranged at a distance from the sleeve tubes of the radiator arrangements, wherein the method includes the following steps: measuring the UV radiant power emerging from the sleeve tube; measuring an amount of the transmitted radiant power by the further UV sensor; and determining the transmittance of the water by an amount of the emerged radiant power and of the transmitted radiant power.

摘要： An ultraviolet mercury low-pressure amalgam lamp includes a tube having a first end and a second end, a first electrode placed in the first end of the tube, and a second electrode placed in the second end of the tube, whereby when the lamp is energized a discharge path is formed between the first and second electrodes. At least one amalgam deposit is adjacent to one of the first and second electrodes out of the discharge path between the first and second electrodes. The tube has at least one constriction, wherein the at least one amalgam deposit is placed behind the constriction with respect to the discharge path such that the at least one amalgam deposit is protected by the constriction from the heat emitted by the electrodes.
