In general use the highest valve positioner gain that does not cause oscillation. For pipeline flow and pressure control, oscillations are not filtered.

Research offers fault detection technique for insulated-gate bipolar transistors open-circuit faults in voltage source inverter-fed induction motor drives.

By Jon Moscovic, Lead Reliability Engineer, SABIC SABIC’s situation proved to be harder than most typical applications due to a mix of specific conditions. For many years operators struggled while working with paramagnetic and electrochemical cell sensors.

Through demonstrations, presentations and one-on-one discussion with leak test experts, the Nov. 8 Leak Test Workshop will give practical information and ideas that attendees can take back to their factories and implement for a better, faster and more reliable leak test.

An actuator is a device that applies the force necessary to cause a valve's closure member to move.

The Egyptian Construction Authority for Potable Water and Wastewater (CAPW) recently sourced four custom-made pump drives from special motor manufacturer Menzel Elektromotoren for installation in a water pump station in Cairo.

The aim of the project is to increase the field's oil production capacity to 65,000 barrels per day (BPD) from the existing capacity of 22,000 BPD.

In plant installations, a key requirement is the ability to smoothly integrate actuators used for opening or closing valves with the automation system.

Learn how to use key PID features that can greatly expand what you can achieve. Includes innovative application examples for feedforward and rate limiting.

The option allows PLCs running the Modbus industrial automation protocol to connect to Alicat instruments over Ethernet cable.

The Norwegian enterprise holds the rights to FluidCom, a chemical injection metering valve (CIMV). FluidCom prevents blockages and corrosion in oil wells, pipelines, and other facilities and employs a patented technology for thermal control.

By Jeff Miller, Optical Cable Corporation (OCC) Fiber optic cabling upgrade helps fend off lightning strikes, gnawing animals, environmental toxins, and other threats that can interrupt critical communications and control. Concerns of this kind recently drove the Tampa Bay Regional Surface Water Treatment Plant to upgrade from PE-89 outdoor direct burial copper cable to fiber optic cable.

By Tom Bass, Emerson Automation Solutions Pumps in remote locations can be monitored with wireless transmitters in a cost-effective manner to improve uptime, avoid incidents and increase reliability.

The Calibration Handbook of Measuring Instruments by Alessandro Brunelli, an expert in the measurement and automation of industrial processes, helps guide and manage industrial process measurement

The Product Knowledge Workshop will take place on October 4-5 in San Marcos, California, and October 17-19 in Beijing, China. These workshops are designed to provide customers comprehensive training on FCI thermal dispersion mass flow meters, flow switches, and level switches.

The data that is really needed when selecting and sizing a control valve is rarely understood and specified.

One significant order involves the supply of 70 LP range linear pneumatic actuators for the operation of large gate valves. The order for these actuators includes the assembly and factory testing of local control panels with digital valve positioners.

The three-day class, from June 6-8, will focus on physics of flow and various flow measurement technologies available, along with a basic understanding of digital communications. The course will be a combination of classroom and hands-on training.

Dr. Wade—who has more than 50 years of experience designing, applying and installing process control systems—says the updated edition builds upon the real-world experiences and process knowledge of engineers and technicians to demonstrate the application of successful regulatory control strategies and techniques.

At the March 22-23 event, Festo and Siemens will demonstrate the Multi-Carrier System, a mass customization transport solution. Festo will provide strategies for smart manufacturing during presentations on Wednesday and Thursday afternoon.
