Field device receives Hart approval

The Hart Communication Foundation (HCF) has registered the first field device verified using the approved Hart 7 test specification.

The Hoffer Flow Controls HRT1 rate indicator/totaliser has been verified by the HCF to successfully meet the Hart 7 Protocol standard and now carries the 'Hart Registered' mark.

'The foundation defines test and registration requirements for all Hart-enabled devices,' said Ed Ladd, HCF director of technology programs.

'This rigorous registration and testing process verifies compliance with the Hart Protocol Specifications.

'This is the only way for a manufacturer to obtain a "Hart Registered" certificate and users can be confident that a device carrying this mark is verified and registered with the HCF.' Using the Hart Protocol test tools, suppliers test their device to verify conformance and then submit the test data, documentation and the device to the HCF.

The HCF conducts comprehensive, independent testing to verify compliance to the Hart Protocol Specification.

This process also verifies interoperability between different device suppliers.

The Hoffer Flow Controls HRT1 is a loop powered indicator that accepts inputs from pulse generating devices including flow meters, tachometers, and so on.

It includes support for linearisation, alarms and a non-resettable grand totaliser.

By incorporating Hart 7 technology, the HRT1 provides an upgrade and migration path to Wireless Hart communication for future product enhancement.
