Calculation of formula for pasteurization value

Description
Pasteurizing plays an important role in
many processes of the foodstuffs industry.
During pasteurizing, the processdependent
”pasteurizing value” (PV)
must be maintained accurately, in order
to ensure reliable results.
Previously, the process was controlled by
means of a PLC with integrated loopcontrol
software. Computation of ”PV” in
the PLC required considerable programming
expense and placed a high working
load on the PLC, because the computation
is complex and includes natural logarithms.
Moreover, a local operating
terminal is necessary.
The multi-function units KS 98 and KS
98plus now enable the manufacturer to
install a single device that provides loop
control, sequencing, visualization, and
operation of all the process values concerned.
