Temperature sensors successfully trialled by Food Standards Agency

Telemetry Ltd’s sensors can monitor foodservice equipment temperatures in real time.

A real time digital temperature monitoring system for foodservice outlets has been put through its paces by the Food Standards Agency (FSA).

The government body published a feasibility study following a trial of Telemetry Ltd’s temperature sensors and data management software in eight different food businesses, including a number of street food traders, over a 2 month period in three different London Boroughs during May and June 2018.

Food Safety Officers from each borough were involved in evaluating the reliability and accuracy of the data from the Tonbridge, Kent-based manufacturer’s systems, with oversight provided by FSA.

Telemetry Ltd MD Piers Skinner commented: “We’re delighted that the FSA chose us to take part in its first ever feasibility study into the use of standalone equipment temperature sensors, and that we have successfully demonstrated across a wide range of different foodservice environments that automating this part of the HACCP process can be done more accurately and reliably than human checks.

“The true art isn’t just in accurately recording temperatures, it’s in how you get the data out of small, enclosed spaces and up to the cloud, reliably and in real time. The secret to our sensors is that they use multiple platforms to transmit the data, depending on what you need to know, how often you need to know it, and where you are.”

He added: “Cash-strapped food operators and environmental health officers are a tough audience to please, but the feedback we received from them about our sensors was extremely positive encouraging. With the potential staffing issues that the new Brexit deal might bring, they have all recognised that there is a place for a cheap and reliable system that can save valuable admin time and allow businesses to concentrate on being customer-facing without compromising food safety.”

Telemetry Ltd’s technology can automatically monitor the real time performance and location of many types of restaurant equipment including fridges, freezers, vendors, chillers, hot-holding areas, flow-through water filters, and drinks dispensing system temperatures.

The standalone sensors used in the trial transmitted data using both a 3G LP-WAN network and the Sigfox wireless network. Neither requires the use of host WiFi thus enabling signals to be transmitted from remote street food pitches as well as permanent restaurant locations. The IP-protected sensors are battery-powered with a 5 year lifespan.
