Description of funtion
Features
- 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.
