KELLER DCX-16 Pressure Level loggers

Product Description

The DCX-16 data loggers have a diameter of just 16 mm and can be used in tight spaces. Thanks to their long-life battery, they can keep measuring the water level, water pressure and temperature for years (up to 4 years at a rate of one measurement per hour). The logger can be configured using the supplied software (measurement interval, incident management, delayed measurement start etc.) and data that has been read can be displayed in a graph or chart, corrected using air pressure values, converted into fill levels or other units, and exported.

DCX-16 The sensor, electronics and battery are accommodated in one housing. To extract data, the data collector must be removed from the measuring point, and the watertight screw cap that allows access to the read-out plug/interface must be unscrewed. The DCX-16 operates with an absolute pressure sensor. In shallow water, when the influence of air pressure fluctuations has to be taken into account, a second logger (barometric logger, obtainable separately) positioned on the surface of the water must be used to record the air pressure progression. The com-puter software then calculates the differential pressure or the water level by subtracting the two measured data.

DCX-16SG/VG Instead of a watertight screwed closure, these versions have a cable output. The interface plug is fixed on the sounding tube above the surface of the water with the help of a screw-on fixing disk. This means that there is no need to remove the DCX-16SG/VG from the sounding tube in order to read the data. In the VG version (reference pressure measurement), the reference pressure-compensating capillary is routed in the same cable into the read-out plug housing; this also contains the reference aperture (protected by a Gore-Tex® diaphragm) which produces the pressure equalization.
