VISIFERMTM; Optical Oxygen Sensors with Built-in Transmitter
Sep 01 2009
VISIFERMTM 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 VISIFERMTM 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 ModBu
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.
