MJK Oxix ® Dissolved Oxygen Transmitter

 
 
  • MJK Oxix ® Dissolved Oxygen Transmitter to measure dissolved oxygen in water and wastewater processes.
  • When the sensor’s built in tubing connection is connected to a valved air or water line, a regular flushing of the optics can be controlled by the converter.
  • The sensor utilizes an optical technique that does not consume oxygen like all standard membrane sensors.
  • The sensor has a light source (LED) transmitting light at a specific wave length to the backside of the optical window covered with a special gel.
  • A fluorescing process occurs depending on the amount of dissolved oxygen in the liquid and the sensor determinate the oxygen level as a function of the fluorescing process.
  • The sensor has a range of 0 – 25 ppm, with a resolution of 0,02 ppm and an accuracy of 1 % or 0,02 ppm.
  • The temperature range is 0 - 50°C / 32-122°F 
  • The converter has a logical menu structure with mobile phone type navigation.
  • A number of selectable languages in the large graphical display.
  • The display indicates the measurement in engineering units and has a built-in data logger with a memory of 160.000 data points with time/date stamp.
  • The logged measurements can easily be transferred as a CSV file to a PC using the buil-in USB port and this allows easy spreadsheet data analysis.
  • The converter has a 4-20mA output, two relays for control or alarms, and a digital input for automatic range changes and more calibration curves.
  • Alarms are also indicated as pop-up menus and stored in the converter’s alarm log.
  • The display is configured by the operator so only the relevant data are indicated with an option to name the display with a site tag name or number.
  • The converter has a time function to control the cleaning system for the sensor for almost maintenance free operation. 
  • Converter can work in networks with other Oxix® units, other MJK products, or with third party SCADA and telemetry systems via is RS485 Modbus communications.
  • The display can supervise, set-up and operate up to four Oxix®or other MJK devices for enhanced economies of space and lower cost.
  • The MJK Oxix® Ball Float rises and falls with the water level keeping the MJK Oxix® Transmitter right where it needs to be.  
  • A mounting kit with a float has been developed which holds the Oxix® sensor at the optimal measurement depth.
