Casestudie Breakdown prediction Contell PILOT - Transumo

1. Temperature verification in retrospect
2. Online comparison of current temperature values to a specified range
3. Online comparison and data analysis in retrospect
The following subsections will introduce major products, representing these types,
and will review their compliance to the requirements. Moreover, differences to XiltriX
will be pointed out.
3.5.1 3M FreezeWatch and 3M MonitorMark Indicators
The company 3M offers two very simple temperature monitoring solutions. They
are called “3M FreezeWatch Indicator” and “3M MonitorMark Time Temperature
Indicator” (pictured in Figure 3-10 and Figure 3-11). Both products are designed for
short term temperature verification in retrospect, especially during shipment.

Temperature Indicator [3M2006]
The FreezeWatch Indicator consists of an ampoule with an indication liquid inside.
This ampoule is placed near the transported material during shipment. As soon as a
critical temperature is reached, the indicator paper on the backside changes color
forever. This enables the receiver to verify, whether a critical temperature was
exceeded during shipment, or not. The FreezeWatch is available as a 0°C and as
a -4°C version. [3M2006]
The MonitorMark Time Temperature Indicator is based on the same idea. Beside
the indication of a temperature exceeding, it offers additional basic information of
duration or maximum temperature. As soon as the critical temperature is reached,
the indicator paper starts to turn blue from the left to the right, the higher the
