In-line Chlorine Sensor for Water, Wastewater, Municipal & Industrial Sensing Applications

The KAPTA 2000-AC2 new generation sensor is the answer from ENDETEC to in-line water sensing needs. With a complete line of amperometric probes, the KAPTA product range from Veolia (France) offers unique environmental detection solutions for water quality distribution networks and industrial process control. Utilising unique, micro chip technology the KAPTA sensors are designed for multi-parameter sensors to be fitted within one probe head. Enhancing traditional probe manufacturing methods by bonding sensors and membranes to the probe surface allows for continuous measurements of impurities at high water pressure. This solution allows for the insertion of the KAPTA sensors directly into a water network.

The KAPTA 2000-AC2 sensor solution has been specifically developed to measure active chlorine (HOCl) and temperature directly within a pressurised pipe. The applications include management and control of a drinking water network, real-time, rapid control of chemical dosing for industrial water processes, protection of membranes and cleaning regimes and management of chlorine levels within swimming pools and spas.

The KAPTA 2000-AC2 is an amperometric sensor using a structured photo-polymerised membrane directly on the electrode which suppresses the well-known drawbacks of amperometric sensors with electrolyte, such as pressure and flow sensitivity. This enables the probe to be installed directly within pipes up to 10 bar flow pressure without flow or pressure control. The sensor principal also eliminates the need for field re-calibration and on-going routine membrane replacement allowing both long-term stability of the signal and reduced maintenance costs.

The sensor design includes a simple replaceable head which is easy to handle and requires no reagent or electrolyte. As the lifetime of the sensor can vary by application, this design allows more flexibility and price improvement for critical applications.

The KAPTA 2000 controller is capable of measuring chlorine, ORP, pH and temperature and is fitted with 2 current outputs, 4 relays and P.I.D. functionality allowing up to 6 external points to be measured or controlled. Operation of the controller is simple with a 128x64 pixel resolution graphic display providing continuous readout of chlorine / temperature measurement and status of the control output devices, selectable in a choice of 5 different languages (English, French, German, Italian and Spanish).

The controller is IP66 rated, wall mounted and equipped for RS485 serial port communication for remote monitoring and data storage. On-board software is designed for 2 point calibrations to ensure accuracy, reliable performance and sensor diagnostic information.
