The Ubisense Intrinsically Safe Tag is a small, rugged device that, when worn by people or attached to objects, allows them to be located to an accuracy of 15cm* in 3D. It is specifically designed for use in harsh industrial environments with IS certification requirements. In addition to its tracking capabilities, it includes additional features such as an LED for easy identification, a motion detector to instantly activate a stationary tag and a push button to trigger events.

Features

Accurate LocationThe tag transmits ultra-wideband (UWB) radio pulses which can be used by the Ubisense location system to find its position to within 15cm in 3D dependent on system configuration and environment. By using UWB, the system’s accuracy is maintained even in cluttered, multipath-rich indoor environments. The Ubisense UWB location system is the only one capable of measuring both Angle-of-Arrival (AoA) and Time-Difference-of-Arrival (TDoA) of the tag’s signals, enabling it to generate accurate 3D tracking information even when only two sensors can detect the tag.

Two-way CommunicationUbisense tags employ a unique dual-radio architecture – in addition to the one-way UWB radio used for tracking, tags have a conventional bi-directional 2.4GHz radio for control and telemetry. The two-way communication capability allows the Ubisense system to dynamically manage the tag’s update rate, flash the tag’s LED, report battery status and button presses, and wirelessly reprogram the tag to enable new features.

Flexible Update RatesThe Ubisense software platform allows the tag’s update rate to be dynamically and automatically varied depending on tag activity. If the tag is moving quickly, a high update rate can be assigned for best tracking; if it is moving slowly the update can be reduced for best battery lifetime. When stationary, tags sleep to conserve power, an inbuilt motion detector ensures the tag transmits again as soon as it is moved.

Rugged and AdaptableThe IS Tag is designed to be rugged for use in harsh industrial environments. It is mechanically robust, dust- and water-resistant, and can be securely mounted using a variety of attachment mechanisms.

IS CertifiedThe Intrinsically Safe Tag is specifically designed to be used in hazardous areas with explosive atmospheres, such as oil refineries, chemical plants, paint manufacturing, textile mills, etc.

Long Battery LifeThe tag’s low current consumption and power management techniques result in long battery lifetimes. In an example application, where a tag is used to locate an office worker every three seconds during working hours, it has an expected lifetime of over four years.** Status reports and alerts make maintenance easy and batteries can simply be replaced.
