Histogram Functionality Description
The Processor of DLR-TL001 is dedicated to acquire &
store, check, perform calculation, format data and output
the most urgent & significant items to a reader, starting
from the temperatures sampled in a very flexible and pro-
grammable way. Statistics, Means, Alarms, are processed
by using an “HISTOGRAM BINS DATA SCHEME” that
reduces the active current consumption time.
The DLR-TL001 tag allows to define up to 16 different his-
tograms bins. The user can decide the upper and lower
temperature limits for each bin: the lower limit of each bin
is equal to the upper limit of the previous bin, while the
upper limit can be defined by the user.
The sample time is programmable for each histogram
(and can be even modified inside it under specific preci-
sion needs), the relative threshold alarms can be enabled/
disabled independently.
Histogram bins configuration allows also to control the
storage of the samples inside the logging memory: for
each bin the user can choose to store or not the tempera-
ture value and its time stamp in the memory.
This allows a better handling of long term deliveries by
memory saving. Time stamps storage helps to keep track
of the chronological sequences.
Mean Kinetic Temperature Calculation
The Mean Kinetic Temperature (MKT) is a simplified way of
expressing the overall effect of temperature fluctuations
during storage, transit and shipment of perishable goods.
DLR-TL001 tag updates the MKT at each temperature
