Product description

The ALCOSENS alcohol measuring system enables dynamic online monitoring of production procedures, in which the alcohol concentration in aqueous solutions is significant.

Fields of use:

Baker's yeast fermentation
Pichia Pastoris fermentation
Monitoring of the alcohol concentration in process plants (dealcoholisation, distillation, etc.)
All processes, for which alcohol is important as a reference variable
Acetic acid fermentation (see here for more details)

The probe is directly immersed into the medium being monitored using a probe flange. The alcohol (methanol or ethanol) diffuses using a special membrane system in a measuring chamber inside the sensors. The change in electric resistance of a semiconductor with changing alcohol content is measured by an amplifier taking also into account a compensation of the temperature.

The ALCOSENS probe can be sterilised up to 143°C.

Product characteristics:

High level of reliability
Measuring range: 0%v/%v - 6%v/%v
Probe can be supplied in different lengths
CIP and SIP enabled
Display of alcohol concentration
Analogue outlet 4-10 mA / 0-10V
Ethernet or Profibus connection
Remote maintenance possible
Alarm management

Structure and function of the measuring amplifier for the ALCOSENS probe

The measuring amplifier is designed for the connection of one up to 4 probes. Calibration takes place using the touch panel. The alcohol concentration and temperature are displayed online. The output of the analogue signal takes place using a analogue group as a 4..20mA signal or a digital interface.
The measuring amplifier and all necessary electrical connections including the carrier gas supply are installed in a switch cabinet (protection class IP 65) made of stainless steel. All cables are led via glands from the switch cabinet.
The measuring amplifier is for the measuring ranges of

0 %v/%v - 0.6 %v/%v
0 %v/%v - 6.0 %v/%v
Other m
