SentrOxy - Model aDO-20 -Optical DO-Sensor

• For HMI/PLC/DCS/SCADA users
• Public MODBUS interface
• Easily configurable with Sentro.io interface from aDO-Sensor and a Mobile-App: no need to disconnect the sensor, no need to implement specific configuration registers, and can be used directly in the field
• The Sentro.IO can also be used for example to read the current device status, the cap status, to select the set parameters of the Software-Control-Unit, and much more
• Dynamic output slots let users show more values by rolling outputs in the light register than any existing display has available
• Field adjustable in less than 2 minutes for DO or Temperature without needing disconnect the sensor from the installation. This is achieved using the smart Calibration Cuvette Sentro.IO CUV or the specific Sentro.IO Calibration-TAG for the Temperature. No extra software is required. This kind of adjustment is robust, reproducable and so easy that anyone can do it
• Extensive self-monitoring of environmental conditions, e.g. measuring cap defective or run time close to end
• Alarm-Functions: NAMUR Group-Alarms and detailed Alarm descriptions
• Automatic Alarm when cap time is reached. No need to manage the measuring cap lifetime manually. The Cap-Lifetime is managed by the Cap itself.
• Fully integrated mounting options for tube mounting, bite protection, etc. are available
• POM housing: Robust for use in salt water and against biological contamination
• Optional software control: validated controller results can be read out via MODBUS and no longer have to be programmed in the PLC/DCS. Control functions can get parameter sets configured, which can be selected with MODBUS-Registers

Connection Example 1:

The control functions do not have to be programmed in the PLC. The validated control functions from the aDO sensor can be used optionally. The configuration is very easily done via the Sentro.IO interface of the aDO sensor with a smartphone app. The results of the respective control functions can, for example, be queried by the PLC via MODBUS register. These results can be used for hardware-based control of the actuators.
