The introduction of the new Rotork IQT electric valve actuator brings the advanced functionality and asset management capabilities of Rotork’s 3rd generation intelligent technology to the direct-drive operation of part-turn valves.

Proven in the field by thousands of IQ3 multi-turn actuators, new functionality brought to the compact and robust IQT includes an unrivalled range of advanced data logging and communication capabilities that have been increased in response to the end users’ desire to access more data, both in the field and in the control room.

Diagnostic graphics present a window into the process, showing the valve torque, usage profiles and service logs, facilitating real-time analysis directly at the actuator. The information-rich backlit display is the focus of attention for non-intrusive wireless communication and multi-functional indication, including user-friendly multi-lingual menus for configuration and commissioning. Local position indication, valve and actuator status, asset management and diagnostic operating information is available to download and can be viewed directly at the actuator on the large LCD display. The display provides real-time status data, positional and warning icon information; actuator setup and operating menus along with detailed diagnostic and operational data screens are clearly displayed in dot matrix format.

Using the Rotork Bluetooth® Setting Tool Pro, commissioning and configuring the actuator is faster and simpler than ever. The setting tool can also be used to securely transfer data from the actuators to a PC for analysis using Rotork Insight2 diagnostic software. Insight2 can further streamline actuator set up by pre-defining complete sets of instructions and settings. Each collection of settings can be saved as a ‘mission data set’ and quickly applied to multiple actuators requiring the same configuration.

Valve maintenance requirements can be identified and anticipated, eliminating unplanned interruptions to the process or over-cautious planned maintenance outages. The actuator's powerful datalogger provides comprehensive data capture for planned maintenance and troubleshooting. Data includes valve torque profiles, operational start profiles, vibration and temperature trend logs and an event log. Specific asset management information includes running time, average torque and number of starts. Service or maintenance alarms are selectable from configurable menus including open and close torque levels, total starts and vibration levels.

Torque sensing is reliable and accurate over the life of the actuator. Similarly, reliable valve positioning is critical. A patented absolute encoder with only one moving part tracks valve position without the requirement for a battery even when there is loss of power. In addition, as all configuration and datalogger data is stored in a non-volatile EEPROM memory, all settings are retained. If an actuator is manually operated during a power outage, the local display and remote indication is kept updated by the use of a battery which also facilitates data logging and power-off commissioning.

The IQT’s double-sealed IP68 watertight and temporarily submersible enclosure is universal to all Rotork actuators, including those with explosion proof certification. It permanently protects internal electrics from the ambient environment, even during site wiring with the terminal housing cover removed. The double-sealed design, in which the terminal housing is separately O-ring sealed from the rest of the actuator, has been a standard feature on Rotork electric actuators for over forty years. It is proven to increase long term reliability and durability in the harshest of climates. A plug and socket connector option is available which also retains the double-sealed design.

On the actuator’s compact and robust enclosure, local Open/Close and Local/Stop/Remote selectors are coupled magnetically to internal switches without penetrating the actuator body, further enhancing non-intrusive environmental protection. Emergency handwheel operation with motor preference is provided as standard.

IQT actuators are suitable for three phase, single phase or DC power supplies, with a torque output range of 50 to 2000Nm available for isolating, regulating and modulating duties. The motor always runs in the correct direction, irrespective of supply type and connection. In addition, the output speed can be non-intrusively adjusted over a 4:1 range without affecting the output torque. All valve interface bases conform to ISO5211 or MSS SP 101 and are fitted with removable couplings.

Hazardous area actuators are fully approved to the latest ATEX standards. Network connectivity options include Foundation Fieldbus®, Profibus®, HART® and DeviceNet® open systems, as well as Rotork's own dedicated Pakscan wired or wireless systems.

Yokogawa Electric Corporation announces the release on this date of the SensTation pH/ORP measurement system, a scalable and integrated solution that combines the unique capabilities of the SENCOM pH/ORP sensors and the SMARTDAC+ data acquisition and control system. This solution eliminates the need for a pH/ORP transmitter and allows users the choice of any of the paperless recorders in the SMARTDAC+ series, each of which can connect to up to 16 sensors. In addition to supporting a wide range of analytical and data control applications, this solution improves maintenance efficiency.

Liquid analyzers are used in the oil, petrochemical, iron and steel, electric power, water supply, wastewater treatment, and many other industries. These analyzers are necessary to control the quality of raw materials and products, monitor reactions, and manage water treatment. Conventional liquid analyzers are composed of a sensor and a transmitter that converts the sensor's analog signals into digital signals for transmission over communications networks and the real-time display of data.

Data acquisition systems are often used in plants to collect and log data from liquid analyzers. In 2013, Yokogawa released the SENCOM series of pH/ORP sensors, which are able to process digital signals and store calibration data and other types of information in digital form. This eliminates the need for a transmitter and allows direct connections with PCs and other digital devices. SENCOM sensors come with a communication interface and custom-made pH/ORP display templates for use with the SMARTDAC+ recorders.

Key Benefits:

• Easy to maintain
• Easy navigation and high flexibility and expandability

Since the ’80s Sierra has been among leaders in designing and manufacturing electromagnetic control valves used in our flagship SmartTrak mass flow controllers and legacy 800 series. The catch is that in the past customers had to buy the mass flow controller to capitalize on our precision control valve. Now, after 30 years of field-proven technology, customers can purchase the SmartVO, our stand along precision gas control valves at a lower price point and smaller footprint than our SmartTrak line.

In many analytical and laboratory applications, our customers require 5 mass flow controllers in a cabinet and 50 gas control valves. Now customers can get the complete turnkey solution for precision gas flow control from Sierra which saves customers time in installation, usability, and integration.

Emerson Process Management has introduced the CSI 3000 Machinery Health Monitor, a compact protection system for a wide range of machinery such as pumps, compressors, centrifuges, blowers, and generators. The CSI 3000 delivers protection data in situations where a standard rack-based system simply will not fit or is not a cost-effective approach. Easy assembly and user-friendly, customizable setup means the CSI 3000 has a short path out of the box to improving availability and ensuring safety of rotating assets.

The CSI 3000 measures shaft vibration, bearing vibration, position, speed and generates key signals. The system provides the user with alarm outputs for each channel and does not require additional signal converters for shaft vibration and displacement measurements.

“Emerson offers a complete line of protection monitors – from the rack-mounted CSI 6500 online monitoring system and the basic CSI 9360 Vibration/Position Transmitter, to the CSI 6300 SIS that guards against overspeed conditions,” said Björn Müller, Emerson’s product manager of online sensors. “This is another example of how we are delivering capabilities that bring stability to our user’s operations through services and technologies that reduce downtime and improve availability.”
