Emerson unveils four-wire intelligence

London - Emerson Process Management has launched two new versions of its Rosemount Analytical Model 1056 analyser, which are designed to provide complete HART and Profibus DP digital communications capability. The 1056-HT and 1056-DP 4-wire dual-input models offer operational and maintenance advantages in plants using these digital protocols and are being introduced in response to demands from end-users and OEMs, the company said.

According to Emerson, the HART-enabled analyser allows remote calibration, continuous monitoring of four live process variables and configuration from its AMS Suite or DeltaV host applications, legacy DCS, or SCADA systems. These diagnostics capabilities, it noted, allow plant operators to estimate the life of in-process sensors and perform required maintenance on a more timely basis than before.

The 1056 model is described as 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. Installation is facilitated by modular boards, removable connectors, and easy-to-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 Emerson's Rosemount Analytical division. “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."
