Hybrid stepper motor/lead screw actuator.

Thomson Industries has expanded its line of stepper motor linear actuators with models featuring built-in anti-rotational guidance. The new motorised lead screw actuator (MLA) product saves designers of high-precision, shorter-stroke applications the cost, time and maintenance worries related to designing and building externally guided systems themselves.

The actuator configuration provides effortless integration into your assembly with the same range of end mounting and connection options as the rest of the motorised lead screw family
“Combining lead screws and stepper motors is a simple and cost-effective method of achieving precise linear motion,” said Thomson Product Design Engineer Julian Anton. “However, accomplishing that with basic stepper motor and lead screw assemblies can require designing costly external anti-rotational guidance systems. With our new MLA product line, customers who want precise motion can just specify load, stroke length and end mounting, and they are good to go.”

The load of a typical stepper motor linear actuator attaches to a nut that rides back and forth as the screw turns. Translating the rotational motion of the motorised lead screw into the axial motion needed to move the load back and forth requires restraining the nut. Traditionally, application designers accomplish this with external guidance assemblies, but these can take up valuable space and add cost and complexity.

The MLA design eliminates the need for external guidance by surrounding the shaft with an aluminium cover tube with moulded internal splines that lock onto the nut to keep it from turning. This design also features an integrated bushing that enables it to withstand small radial and moment loads.

It is best suited for space-constrained, force-sensitive applications requiring shorter strokes that must be repeated with high precision. Examples include adjusting a microscope slide stage, tilting a computer monitor or vertically positioning a pipette onto a test tube array. Ideal applications have stroke lengths shorter than 64 mm; have loads lighter than 890 N on various motor sizes; and require speeds below 500 mm/s.

Thomson MLA stepper motor linear actuators are available immediately for NEMA 8, 11, 14, 17 and 23 motor frame sizes; in single or double stacks; with many motor winding options. Linear resolution options range from 0.002 – 0.191 µm of linear travel per step.

The actuators ship with NEMA-standard bolt-hole patterns, but custom pattern profiles are also available, as are custom end mounting, wiring, cabling and connectors. Because the lead screw extends from one face of the motor only, devices such as rotary encoders can also be attached easily.

Vibration monitoring delivers machinery health.

To help users further enhance the reliability of rotating assets, Emerson has upgraded its portfolio of machinery health monitoring systems to deliver asset protection and fault prediction in more places and with faster response than ever before.

Both the AMS 6500 Machinery Health Monitor and AMS 2600 Machinery Health Expert systems have been redesigned to improve performance and fully comply with the European Union’s Restriction of Hazardous Substances (RoHS) Directive and Registration, Evaluation, Authorisation, and Restriction of Chemicals (REACH) Regulation. In addition, the AMS 6500 ATG protection system has been certified as meeting the International Electrotechnical Commission’s (IEC) risk reduction requirements for safety integrity level (SIL) 2, giving users added assurance that it will reliably deliver appropriate insight into the health of critical assets.

The newly redesigned systems will include Modbus™ compatibility and Emerson’s patented PeakVue™ technology as standard features. Field-proven to be an effective and reliable indicator of mechanical damage severity, PeakVue filters out most vibration signals to focus on impacting, providing more effective and reliable indicators of overall asset health.

“Online monitoring helps organisations stay aware of moment-to-moment asset health, particularly on their most critical assets,” said John Turner, product manager for online prediction at Emerson Automation Solutions. “New features in the AMS product portfolio will give users essential and timely online monitoring data and help to improve compliance, even under the most restrictive conditions.”

The AMS 6500 and AMS 2600 systems, which help users effectively plan maintenance, now meet IEC 60068 standards for withstanding shock and vibration, allowing users to safely deploy them in harsh environments where ambient vibration and possible electrical shocks present the risk of damage, such as on wind turbines. A new processor boots faster, and the solid-state drive (SSD) technology can handle transient file transfer 10 times faster, resulting in improved and more responsive asset prediction and process health analysis.

The new processor requires AMS Machinery Manager 5.61 with a firmware patch, or any higher version of AMS Machinery Manager. The AMS 6500 ATG advanced prediction application is compatible with AMS Machinery Manager 5.7 or higher. AMS 6500 prediction monitoring system cards are backwards compatible with all AMS 6500 hardware systems.

The AMS 6500 ATG system, which features embedded predictive diagnostics and optional advanced prediction capabilities, has received SIL 2 certification. Whether organisations need certified equipment to meet company guidelines or to comply with legal requirements, SIL ratings help users evaluate whether a specific technology meets the selected risk tolerance for essential equipment such as steam and gas turbines in power plants or critical refinery and nuclear industry assets.

“More and more organisations are finding they need SIL certified products to meet international standards and machine directives,” said Björn Müller, product manager for online systems and sensors at Emerson Automation Solutions. “SIL certification is one more way we can help customers achieve compliance while demonstrating our commitment to risk reduction.”

Capturing time-critical data using GPS.

Digitization and the reliability of accurate measurement data are inherent to the constantly expanding demands of the energy distribution and production industries. And consumers are also demanding more accurate and traceable data to protect them from damage and costs as well as to continuously optimize their energy consumption. But what if systems or transformer stations are not yet linked to the digital world and time-critical data still has to be available?
To provide this capability, Camille Bauer Metrawatt equips its highly-accurate measurement devices in the SINEAX AM, SINEAX DM5000, LINAX PQ and CENTRAX CU series with GPS modules. The pre-configured GPS modules synchronize the integrated time measurement of the devices using GPS signals, to ensure that each measurement value is recorded with the globally correct date and time. Timestamps are important when performing sensitive energy measurements. And also, when problems occur, they can be promptly detected before it becomes too late. If the fault has already occurred, accurate data with a precise timestamp are essential to be able efficiently pinpoint the causes.

When there are specific network quality issues, either with respect to IEC 61000-4-30 Ed.3 norms or non-standard network criteria (for example absolute performance monitoring, individual threshold exceedances) accurate timestamps are a must. They make it possible to supply the event monitoring software reliably with time-critical data. As well as this, standardized, IEEE 1159.3-compliant, PQDIF files can be retrieved, saved and read with accurate timestamps directly from the device using PQ-DIFFRACTOR or the SMARTCOLLECT data management software. Accurate timestamps are also an essential component of automation applications; for example lighting controls, network load symmetrization and monitoring of production resources such as transformers, motors, etc.

The official designation of GPS is "Navigational Satellite Timing and Ranging – Global Positioning System" (NAVSTAR GPS) and it is now pervasive in mobile devices like smartphones and navigation devices. Each satellite is equipped with one or more atomic clocks. The major advantage of GPS signals is that GPS receivers only receive data from satellites but do not transmit. Because the position detection is normally done by computing the signal propagation times between the satellites and the GPS receiver, no information can flow to unauthorized third parties.

Workspace offers safer, more connected operating area!

The iOps Workspace Solution is a new operator workspace from Emerson that reduces human error and creates an ideal operating environment. The integrated operations (iOps) solution combines visualisation hardware and software with an advanced technical console to enable an operator to more quickly interact with multiple information sources, improving productivity and situation resolution.
Basic Configuration
The iOps Workspace Solution - developed in conjunction with workspace providers Barco, Vertiv and Evosite - combines many operator input sources into a single, virtual workspace - integrating information at the operator interface. Operators only need to log in once, at a single workspace, to gain access to all monitoring and control areas for which they are responsible.

“Emerson’s new iOps Workspace Solution - with its customisable user interface, enables operators to securely control and monitor numerous sources residing on different networks” says Todd Brase, project services marketing manager for the iOps Workspace Solution. “This provides the operations team with a common operational picture, helping them to make better decisions faster.”

Applicable across multiple industries, the new solution especially suits oil and gas, refining, petrochemical, and life sciences operations where a centralised control room is used to manage multiple process areas and interact with a myriad of enterprise applications. The iOps Workspace Solution can manage inputs from any number of third-party software applications, live video feeds, and Emerson’s array of automation software and hardware including the DeltaV™ distributed control system. Barco’s operator workspace software, OpSpace provides an `integrated at the glass experience’ that helps control room operators work in a more intuitive way.

“We started development of OpSpace by first gathering feedback from operators in the field, describing their ideal way of working,” says Chris Sluys, vice president operator experience and chief operating officer at Barco. “Then we designed the system that answers all their needs. This vastly improves the operators’ efficiency and effectiveness, and ultimately raises the quality of decision-making.”

Vertiv and Evosite offer advanced technical furniture designed to operate 24/7 in control rooms and operations centres. Combining adjustable sit-stand settings with spacious, high-pressure laminate work surfaces gives operators an ergonomic work area that reduces strain and allows them to work more effectively.

Time-Of-Flight 3D cameras.

Stemmer Imaging has signed an agreement with Odos Imaging for the distribution of Time-Of-Flight (TOF) 3D cameras. The cameras will be available through Stemmer's entire distribution network of 19 different countries in Europe. Odos Imaging is part of Rockwell Automation.

The Starform Swift 3D camera has a 640 x 480 pixels sensor, making it the highest resolution industrial TOF camera currently available. With integrated 850 nm LED illumination, the camera can acquire 3D point clouds for imaging at 44 fps from a range up to 6 metres. These fast frame rates can be used to track dynamic scenes in 3D or accumulate static scenes for improved precision. Fully factory calibrated, the camera can provide range (or depth) information, 3D images and measurements and 2D images.

Mark Williamson, Managing Director of Stemmer's British subsidiary, said: “The Starform Swift TOF 3D camera perfectly complements our current range of 3D cameras and opens up a diverse range of depth perception application opportunities. Our extensive technical expertise in creating complete machine vision solutions will allow us to bring added value in a wide range of industrial markets.”

Its versatile imaging capabilities and GigE Vision connectivity make the Starform Swift ideal for a wide range of factory processing, packaging and logistics applications. These include palletisation/depalletisation and pallet management, carton/object dimensioning and profiling, and package completeness checks. Camera-integrated software packages are available for completeness, height detection and box measurement. The GeniCam interface enables easy integration of Starform Swift cameras into popular machine vision software packages (such as Common Vision Blox) easing the development of machine vision solutions.

Sensors, optics, illumination, processing and power are contained in a ruggedized industrial housing. Infrared band-pass filters prevent unwanted light from reaching the sensor whilst the GPIO interface enables individual triggering and synchronization of multiple cameras.
