The Optical Oxygen Sensors is the first self-contained device for optical dissolved oxygen measurement. Combined within the 12mm shaft are: high-temperature compatible optical electronics, a microprocessor, a 4-20 mA analog sink, a digital ModBus, and an ECS interface (for use with existing DO transmitters)! The Optical Oxygen Sensors can be used with existing DO transmitters or the measurement signals to be fed directly into a process control system.

Intelligent Sensor
• Ingenious measurement optics, stable to 130°C, with a symmetrically oriented diagnostic and measurement design.
• Monitoring of all sensor functions, including status and health of the replaceable sensor cap. A history of the self-monitoring is recorded in the sensor,
• Configurable through the RS 485 interface with a PC or via ModBus

Operational Reliability is Paramount

Measurement results can be obtained from the sensor as 4-20 mA sink or digitally. Both types of signal are clearly more robust than the sensitive (nA) signals of a classical dissolved oxygen sensor. With VISIFERM dissolved oxygen sensors, the small currents are dispensed with as the measurement amplifier is built right into the sensor
