Siretta the specialist sensor distributor

As a distributor, Siretta has focussed on being Europe’s leading supplier of specialist sensors. Research and development, scientific and industrial applications typically use these sensors. Applications as diverse as space rockets to the measurement of heat energy produced by pigs use our heat flux sensors

We supply heat flux sensors from Vatell that measure convective, conducted and radiative heat flux. The diverse range of heat flux sensors have ranges from as low as 0 – 5 W/cm² and operating temperatures without water cooling of up to 800 Celsius. Some of these have very fast response times, as fast as 17 µS.

The fibre optic sensors from Fiso measure temperature, pressure, strain and refractive index. Fibre optic technology allows the use of these sensors in applications where electrical isolation is required, or in large electromagnetic fields.

Siretta the cellular products manufacturer

As a manufacturer, Siretta aims to be the leading manufacturer and developer of IoT products, IoT software and IoT solutions. Our specialty being in providing these for Industrial markets and business to business applications.

We have extensive knowledge and experience within IoT with a focus on cellular technologies using 2G (GPRS), 3G (UMTS), 4G (LTE), NB-IoT and LTE Category M wireless technologies.
