Hardware
The basic Food Tracker system hardware comprises:
• Data logger (including communications lead and charger).
• Thermal barrier.
• Thermocouple probes.
Data Logger – the MultiPaq21
The MultiPaq21 has been designed to withstand the most hostile of food-
processing applications and to guarantee operating reliability day after day.
The logger's key features are:
• Temperature and (on 8-channel logger only) humidity profiling.
• Up to eight temperature channels with interchangeable thermocouples.
• Operating temperature −40°C to 85°C/−40°F to 185°F.
• Accuracy to ±0.2°C/0.36°F.
• IP67 water-resistance rating to guarantee reliability/data integrity.
• Programmable (start trigger, sample interval, etc.).
• USB and serial RS232 communication capability.
• Multi-run capability (up to eight separate profiles before download).
• RF telemetry option (on 8-channel logger only).
• Rechargeable NiMH battery (120 hours at 0.5-s sample interval).
Four versions are available: with six and eight data channels, and suitable for
type T and type K thermocouples (see specifications, below).
The MultiPaq21 logger achieves ingress protection standard IP67, which
specifies that, when immersed in water to a depth of 1 m for 30 minutes, water
must not enter in any harmful quantity. The rating is achieved in the logger's
operational state with thermocouples (or blanking plugs) connected; these are
provided with O-ring seals. As an illustration of this (although not
recommended for normal use), the unit has been shown to operate successfully
submerged in water at room temperature without any protection from a water-
resistant thermal barrier.
