Disposal of Loggers
Always adhere to the applicable statutory regulations for recycling and waste
disposal. For details of recycling Datapaq products within the European Union,
see www.fluke.co.uk.
Under the European Union WEEE Directive, users should return all
loggers (whether or not containing batteries) to Datapaq for disposal
at the end of their useful life.
Thermal Protection – Barriers and
Heatsinks
Constructed from stainless steel, with hydrophobic ceramic insulation, the
thermal barrier provides the thermal and mechanical protection necessary
for the data logger to survive in the hostile environment of an industrial oven.
Not all food processes are equal, each having its own demands of space,
temperature, duration or environment (steam, submersion in water or oil). For
this reason the Food Tracker system has a choice of submersible and non-
submersible thermal barriers. Options vary from quick flash-frying, where the
whole system is submersed, to long-duration high-temperature bakery
processes. Datapaq barriers are quality engineered, designed to give maximum
performance with minimum weight and size.
Heatsinks – stainless steel assemblies filled with a non-toxic, non-flammable
phase-changing material – provide additional, secondary protection, allowing the
system has to operate at high temperatures for extended periods. The phase-
changing material absorbs the heat and maintains a temperature of 58°C/136°F
until all the material has changed from solid to liquid state. Temperature-
sensitive labels on the heatsinks provide indication of the maximum temperature
experienced by the data logger, and a warning if the temperature exceeds
77°C/171°F.
The ceramic insulation material will absorb moisture if stored in a damp
environment. Although this will not damage the thermal barrier, its performance will
