A new range of explosionproof digital insertion density transmitters offers cost savings to process engineers. A number of density-derived values-for example, °API, percent solids, and °Brix-are continuously computed within the transmitter, eliminating the need for remote processing in a range of applications. Any computed value is available via the unit's industry-standard 4-20 ma output for controlling valves, mixers, and blenders, while Modbus communications facilitate integration into SCADA and DCS systems.
The new 7828 transmitter range includes versions suited for corrosive environments. Designed for liquids and slurries, the transmitters are self-contained and factory-calibrated and require no routine maintenance.
Data logging and on-line problem analysis of the 7828 are simplified by this firm's Windows-based Adview software. By connecting a portable PC to the unit's RS485 connection, an engineer can quickly check that the loop is functioning correctly or log data for later analysis, making Adview suited for diagnosing problems in wide area installations such as pipelines and tank farms.
