Networking Field-Based Valves On Ships

Helping shipbuilders install reliable and cost-effective field-based communication networks.
For years, field-based networking has been the preferred method for installing control instrumentation and automated on-off and control valves at new industrial plants. There are several reasons for this. Field-based networks dramatically reduce wiring costs. The instruments and valves are easier to install.

Installing an Asset Management System?  Don't Forget the Discretes!  Part 1

In the next two articles I’ll review findings of what users are looking for in this area with a focus on automated discrete (On/Off) valves. I’ll also explore possibilities of putting into place discrete automated valve diagnostic systems that may create real world systems that produce a pay off.

Installing an Asset Management System?  Don't Forget the Discretes!  Part 2

This is the second part of a two part series describing what you can do to take advantage of diagnostic systems for discrete automated valves. In Part 1 I discussed the problems that may occur in most discrete (On/Off) valve systems and the challenges instrument engineers face in diagnosing these problems. In part 2 I’ll describe potential solutions based on your current legacy systems or using emerging technologies with a comprehensive diagnostic capability.

New Field Wiring Architecture Reduces Hazardous Area Wiring Costs By 65%

Dramatic savings may be realized over conventional explosion proof point-to-point wiring (i.e., hard conduit) in hazardous Class I, Division 2 areas by combining bus networking with tray cabling and nonincendive protection concepts. By optimizing protection concepts on a bus network, users can realize greater installation flexibility with a less expensive bulky infrastructure and improved safety. This, in combination with greater field device functionality, such as predictive diagnostics, offers a compelling case for installing this new wiring architecture.

Slash Installation Costs with AS-Interface Bus Networks & StoneL

By utilizing the AS-Interface bus network for discrete automated valves and plant instruments, installation costs may be reduced by up to 49% from conventional point to point wiring. With thousands of installations in the process industries, users have demonstrated these savings in addition to improving process flexibility and reducing plant infrastructure requirements while maintaining instrument reliability.

Prospering with Valves That Think & Communicate 

Technology Improvements Drive the Valve Communication "Revolution"

Increase Your Product Quality by Using Position Transmitters on Modulating Control Valves

This article discusses some of the specific control valve performance parameters that may be accurately measured with the use of a valve position transmitter.

Increase Your Productivity with Proper Sensor Selection

When selecting proximity switches beware that by using this term without any further qualifications you may be getting any number of different switch/sensors.
