Rosemount Analytical 1066 two-wire liquid instruments

Emerson Process Management has released the Rosemount Analytical 1066 two-wire liquid instruments featuring a broad range of measurement parameters, advanced communications capabilities and ease-of-use features. The transmitters are suitable for many industrial applications, including those with exacting performance requirements such as pharmaceutical and food and beverage, and in harsh environments such as chemical plants, metals processing and effluent monitoring.

The series has the latest version of Hart 7, and they are said to be the industry’s first pH transmitters to be registered under the Interoperability Test Kit 6 (ITK6) from FOUNDATION Fieldbus.

The transmitters can measure pH, ORP, resistivity/conductivity, percent concentration, total dissolved solids, total chlorine, free chlorine, monochloramine, dissolved oxygen and dissolved ozone. A second sensor input allows continuous pH correction for free chlorine measurement. The instruments’ SMART capabilities also enable them to accept precalibrated Rosemount Analytical SMART pH sensors, saving time and money for field technicians.

The 1066 Foundation Fieldbus transmitter can use analog output function blocks to link to temperature and pressure measurements from the bus for temperature and pressure compensation, which can increase the accuracy and responsiveness of the measurement. The series also has a full complement of analog control and math function blocks for use by the 1066 or other devices on the bus to facilitate control in the field. ITK 6 compliance also brings with it new features - field diagnostics, which provide users configurable alerts, and common software downloads, making transmitter software upgrades possible without taking the transmitter out of service.

The HART version is switchable between HART 5 and 7. The added features of HART 7 include publishing status and a time stamp with live measurements, and long tag names (32 characters), which makes it possible to more completely describe the location and application of a transmitter.

Housed in a 1/2 DIN enclosure, the series features a large display with ease of use and an intuitive menu system. A diagnostic key allows for immediate troubleshooting. A few keystrokes on simple menu screens will walk the operator through any function quickly and easily.

The HART configuration is fully compatible with the Smart Wireless Thum adapter for immediate commissioning to Emerson wireless networks. For high performance, the series uses low-frequency noise reduction, and includes cable capacitance and series resistance compensation for improved accuracy and reliability. The analyser also has straightforward architecture, fully integrated electronics and automatic self-test.
