Data Loggers Help Improve Food Safety

Many Signatrol products are used for HACCP & EFSIS monitoring but the Signatrol SL7000 is powerful and flexible. The SL7000 series are fully self-contained portable data loggers, that have up to four channels, ideal for monitoring and recording parameters in food manufacturing and storage.

Up to four external sensors can be connected in addition to the internal temperature sensor to record humidity, pressure, voltage, current and pulse signals.

For temperature measurement, the internal cold junction sensor can be complemented by external thermocouple and RTD sensors. Sampling rates from once per second up to once every 24 hours can be set and the units can be configured either on a 'fill then stop' or 'first in first out' basis. Programming and data analysis is carried out quickly and effectively using the proprietary Windows software. Data can be down loaded and either saved to disc or analysed immediately on screen. Information is displayed in tabular or graphical format with full reporting facilities. Data can also be incorporated into other spread-sheet packages.

Up to 64 SL7000 units can be networked together using "standard" USB hubs.

The flexibility of the SL7000 can be radically extended by the use of the Signatrol thermal barrier boxes, which allow the loggers to operate at temperatures up to 350C.
The loggers are kept insulated and sealed inside the stainless steel barrier box while sensors measure the external temperature. This arrangement is ideal for oven temperature profiling to provide documentary evidence that products are reaching and maintaining the required cooking temperatures. The barriers can travel through the oven with the food, thus providing meaningful and accurate temperature data. The data can also be used to optimise cooking times thus maximising throughput and minimising energy usage. The barrier units are equally suited to use in chillers, spiral freezers and blast freezers.

The SL7000 range is just part of the extensive Signatrol range of standard and bespoke data loggers and recorder
