Lyo Control LC
plus
measuring system
The Lyo Control LC
plus
measuring system can be used to determine the
crystallisation state of the product. In the liquid state, the electrical
resistance is very low. During the freezing process, the resistance
increases. The LyoRx control sensor measures the electrical resistance.
LyoLog
plus
data logging software
LyoLog
plus
is a data logging software program by Martin Christ
Gefriertrocknungsanlagen GmbH that is specifically adapted to the
requirements of freeze-drying processes. Apart from the graphical
representation of the measurement data of currently running processes, it
also enables the data export for additional evaluation.
LPC
plus
SCADA system
The Christ LPC
plus
system consists of the Supervisory Control And Data
Acquision (SCADA) software program by Martin Christ Gefriertrocknungs-
anlagen GmbH and a dedicated PC. The system is connected to the
LSC
plus
controller of the freeze-dryer via Ethernet LAN and provides the
operation of all of the freeze-drying functions as well as process recording
(measurement data and process events), process documentation and data
backup. Furthermore, it enables the comfortable administration of freeze-
drying programs/recipes and users.
