The measuring system automatically switches off, if the temperature
of the sensor in the medium exceeds 50 °C during operation (thermal
shutdown). Once the medium has cooled down, measurement auto-
matically continues.
4.7 Permissive Measurement
The sensor with the corresponding transmitters must be purchased
directly from the manufacturer ABER. INFORS HT offers a connec-
tion to the transmitter on the basic unit.
Calibration is performed according to the manufacturer’s guidelines
directly on the transmitter.
Manufacturer: ABER
System: Futura
Measured parameters:
Permittivity in the 0 to 400 pF cm
-1
range
and:
Conductivity in the 0 to 40 mS cm
-1
range
Sensors of the ABER Futura systems measure the permittivity
(also:
capacitance
) and conductivity of the culture. This measured
data can be used to determine a correlation with the live biomass
concentration, for example, using the soft sensor in eve
®
or data
evaluation.
