2 mperometric Sensor Type DOSSens DCL10 for the registration of free, inorganic chlorine, at stable ph-level Special Performance Features: The DOSSens DCL10-Sensor for the of free, inorganic chlorine is a logical follow -up development of membrane-covered sensors. This type of sensors are already approved in disinfection control of potable water and swimming-pool applications over many years. The brand new features of the DOSSens DCL10-Sensors are focused in the practical functionality. pproved electro-chemical meats recent microprocessor technology and produces new synergies and advantages facing the existing sensors on market: Microprocessor-control integrated in sensor-shaft for the output of the sensor signal, already temperature compensated Different signal outputs are realized in only one system: - Current output 4 20 m - Voltage output mv - Serial Interface RS 485 The serial interface provides the following inform ation to a connected controlling system: - Chlorine value, already temperature compensated - Temperature - Operation hour counter - ID-Code and the capability for the connection of several sensors in the same communication system - dd. OEM-specific information, as failure memory, incl. time-stamp for the last 6 faults (e.g. strong osci l- lating values, oscillating power-supply etc.) In addition the DOSSens DCL10-Sensor provides a ma g- nificent new feature: Two LED s placed in the sensor-shaft are showing the actual sensor performance: Green (luminous): - The sensor is working proper - The sensor is detecting chlorine and the chlorine concentration is within the sensor measuring range. Red (luminous): - The detected chlorine concentration is lower or nearby the lower measuring range. The signaloutput is set to 0 m (mv) to block a sensor calibration. Either green nor red : - No power supply. V12/06 Technical and commercial modification and misprints reserved 2
