Wirelss Adapter Unlocks Stranded Information In HART Devices

ABB introduces its loop-powered, small-footprint, FieldKey wireless adapter that unlocks stranded information in existing HART devices. This unit serves as a wireless extension of the HART standard as used in over 30 million installed instruments. It allows users to wirelessly and remotely monitor and configure their instrumentation assets. The adapters are compatible with 800xA asset management software or with the ABB Asset Vision Professional standalone product.

The FieldKey wireless adapter is simple to commission and set up using a hand-held or PC-based software. Users can establish reliable communications via the WirelessHART protocol that supports frequency channel hopping. The protocol automatically builds a mesh network that can re-route communication paths to overcome blocked signals. Encrypted messaging based on AES 128-bit banking standards along with managed join-keys and network IDs provide a secure method of communication.

Benefits of the ABB Fieldkey wireless adapter include:

  • Useful for condition and process monitoring
  • Works with any HART 4-20 mA instrument
  • Easy to install in difficult conditions because of small size
  • Requires no battery to run since it uses Energy Scavenging

The ABB FieldKey wireless adapter mounts into an available cable gland on an instrument and can rotate almost completely around to achieve the best antenna direction. Initially the adapter suits non-hazardous areas, but will be released for hazardous area applications later this year.
