New 4-Wire Intelligent Analysers with Advanced Digital Communications Capability

Emerson Process Management (USA) announces two new versions of its Rosemount® Analytical Model 1056 analyser. The new Model 1056-HT and 1056-DP 4-wire, dual-input analysers include complete HART® and Profibus® DP digital communications capability for full operations and maintenance advantages in plants using these digital protocols.

The HART-enabled analyser allows remote calibration, continuous monitoring of four live process variables and configuration from Emerson’s AMS® Suite or DeltaV™ host applications, legacy DCS, or SCADA systems. The full complement of diagnostics allows plants to estimate the life of in-process sensors and perform required maintenance on a timely basis.

The Model 1056 is a multi-parameter instrument allowing single or dual inputs in any combination of pH/ORP/ISE, resistivity/conductivity, percent concentration, chlorine, oxygen, ozone, temperature, turbidity, pulse flow and 4-20mA current input. The instrument has a large display and intuitive menu screens with advanced diagnostics and help screens. The device is extremely easy to use. Ease of installation is facilitated by modular boards, removable connectors, and easyto-wire power, replays, and analogue outputs. Seven languages for user menus are included with every analyser.

“The new Model 1056-HT and 1056-DP complete our digital communications offering,” said John Wright, Vice President of marketing for the Rosemount Analytical division of Emerson Process Management. “Our customers can now select this easy-to-use multi-parameter workhorse instrument for any liquid analytical application and leverage two of the most popular digital communications protocols available on the market. We’re responding to demand for digital communications worldwide from end-users and OEMs in our extension of this immensely popular instrument.”
