Description of funtion
Functions
- Control of the reference air volume and the purge air volume for an oxygen probe by means of infinitely variable modulation of the pumps
- Generation, storage and display of fault signals in the event of deviation from the specified set values for reference air volume and purge air volume
- Detection of loosened reference air connection at the probe
- By regulating the flow rates and detecting a drop in pump performance, the use of commercially available low-cost pumps is possible without risk.
- Separate pumps for reference air and purge air prevent measurement errors caused by a leaking purge air valve.
- Network interface with Modbus/TCP protocol for providing all setpoints, measured values and fault signals to a higher-level system, with MQTT protocol for integration in Industry 4.0 environments and web server for simple configuration and visualization.
- Seamless recording and documentation of reference air volume and purge air volume possible (CQI9)
- Generation. Storage and display of fault messages such as setpoint deviation (CQI9)
- Early detection for pump replacement or maintenance
- Cost savings through the use of commercially available, low-cost pumps
- Supply with 230V AC max. 250 mA
