E-coli and salmonella food poisoning cases are quite unusual in Britain but it is still important for monitoring the conditions in which food is stored to prevent these bacteria from spreading.

OCC was involved with an important radio-based temperature monitoring and alarm system on behalf of Woodley Electronics. (AAW Control Systems now provide support for Woodley Electronics Systms. AAWCS phone no. is 01488 638928, e-mail address inf@aawcs.co.uk)

Who will it benefit?

The product helps monitor temperatures in small-to-medium-sized installations in the food storage sector, and is used by retail food outlets such as supermarkets and dairies.

Why is it needed?

To ensure that temperatures in food storage refrigerators are maintained within the limits laid down by Environmental Health Regulations. Some insurers require the installation of a system before they will accept claims for food spoilage.

How does it work?

• Temperature sensors within the installations gather data.
• This data is then transmitted at 5-minute intervals by radio transmitters.
• These temperature values are then logged, providing a history of temperatures within an installation for any given period, in minutes or days.
• The current values are also checked against user-defined limit settings.
• If the temperature falls outside these limits, an alarm is activated.

All significant events and alarms are stored and a log of the last 64 events can be printed out, on a regular basis or on demand.

The software developed by OCC for this project is an enhancement to a previous existing Woodley product, a refrigerated transport temperature recorder.
