Data
 
   
 
The DCX-25PVDF data loggers have been specially designed for use in aggressive liquids such as brackish water and sewage. The housing is made of polyvinylidene fluoride and the installed pressure transducer is available in Hastelloy C-276 or titanium 6AL-4V. Thanks to their long-life battery, they can keep measuring the water level, water pressure and temperature for years (up to 10 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.
 
This data collector (ø 25 mm) integrates a pressure sensor, electronics and battery in one housing. The electronics employ the latest microprocessor technology, which give high accuracy and resolution for the pressure and temperature signals. The built-in pressure sensor is mathematically compensated for all linearity and temperature errors. The use of a non-volatile memory ensures high data security.
 
The DCX-25PVDF works with an absolute pressure sensor. For installation, the data collector is secured by a suspension cable and immersed into the media to be measured and must be recovered for data readout. In shallow water, where the influence of barometric pressure changes should be considered, it is recommended that a second data logger (e.g. DCX-22-Baro) is placed at the surface to record the barometric pressure. The Logger PC software then calculates the water depth by subtracting the two measured values. The housing of the data logger can be opened easily without any tools, thus allowing quick access to the replaceable battery and the interface connector for configuration and data download.
 
Interface with a PC is accomplished using one of KELLER’s converter cables which are available in either RS232 connection (K-103-A) or USB connection (K-104-A). The necessary converter drivers are included with converter purchase, along with the KELLER Logger software. This intuitive software provides the capability to customize the instrument, as needed, for each installation. Users can configure the DCX-25PVDF to record at fixed time intervals, using fixed or event-based start times, in user-selectable measurement methods to ensure that only the most useful and meaningful data is collected and stored.
