The development of an optoelectronic on-line carbon dioxide partial pressure probe
Rainer Buchholz,Dirk ltzek,Torsten Steinau,Michael Dieckmann 동서대학교부설연구소 1997 연구소 논문집 Vol.2 No.-
In this work a prototype for an optoelectronic on-line carbon dioxide partial pressure probe was developed. The mechanical arranngement of the optival and optoelectronical compounds was as well as simple, resulting in no changes due to the signal induced by the temperature effects. The resolution for the field of biotechnology with a measuring range from 0 to 100 mbar is at the moment 1.1 mbar with an accuracy of +/- 3 mbar. For the fie이 of beverage industries with a measuring range from 0to 4 bar the resolution is 4 mvar with an accuracy of =/- 25 mbar. The 90% response time by the application of a fibre with a diameter of 1000 microns and a silicone membrance with a thickness of 300 microns is about 8 min. Possibilities were shown to decrease the response time.
