Smart Wireless Family adds Industry’s First Wireless Conductivity Transmitter

Emerson Process Management has expanded its Smart Wireless analytical field instrument solutions with the release of the industry’s first WirelessHART™ contacting conductivity transmitter, the Rosemount® Analytical Model 6081-C. Since more than half of end user liquid analytical applications require conductivity measurement, the new wireless conductivity transmitter is an important addition to the recently introduced model 6081-P wireless pH/ORP transmitter.

Industrial conductivity measurement is valuable for control in applications where measuring and controlling the conductivity of chemical concentration allows effective scrubber performance, where detecting leakage of cooling water from jackets or heat exchangers into processes allows contamination to be avoided, or where leakage of the process into the cooling water enables fouling or corrosion to be avoided. It is valuable for equipment protection as well, such as its use for monitoring boiler feedwater and permeate, to ensure pure mineral-free water, which is important for protecting condensers, heaters, pumps, piping, boilers, and turbines that produce power.

Wireless technology is ideal for conductivity applications that are too difficult to reach, too dangerous to access, or too costly to perform with a wired transmitter.

“The success of the Model 6081-P pH/ORP analyser introduced last year has only increased customer demand for a conductivity version of our wireless transmitter,” commented John Wright, vice president of marketing, Emerson Process Management, Rosemount Analytical. “As with our wired analytical family, our customers want the broadest possible range of wireless analytical measurements. The wider range of measurements enables them to take advantage of a common design, reducing training time and increasing application flexibility for end users, integrators, skid manufacturers and OEMs.”

The Model 6081-C is compliant with the WirelessHART™ communications standard, so making it fully compatible with a host of other wireless devices. All Emerson wireless devices, including the Model 6081-P and 6081-C, function in a self-organising network in which every wireless device in the network acts as a router for nearby devices. This assures very high data transmission reliability and network availability; all devices work together to identify the most efficient communication path, regardless of radio interference sources or barriers that may inhibit wireless communication.

In addition to its wireless capability, the Model 6081-C offers a range of unique features that differentiate it from other conductivity transmitters. The transmitter is compatible with both 2-electrode and new 4-electrode sensors. It is also compatible with Emerson’s AMS® Suite predictive maintenance software for fully integrated access to predictive diagnostics in a comprehensive asset management application. The Model 6081-C offers a measurement span from 0 to 600,000 μS/cm, which makes it ideal for a wide range of industries and applications.

Advanced diagnostics allow real-time monitoring of sensor condition for efficient maintenance scheduling. Local device keypad access permits setup, configuration and trouble-shooting in situ. Quick Start menus enable in-process deployment within one minute. Intelligent power management extends power module life and reduces replacement frequency. User menus and prompts are available in six languages. The security of wireless devices and networks, a key concern in industrial environments, is assured with Smart Wireless technology by Emerson’s five level security implementation, which includes encryption, authentication, verification, anti-jamming and key management.
