Measurement System for High-Vibration Environments

Hexagon Metrology has announced the immediate availability of its new white-light measurement products, the manual Cognitens WLS400M and automated Cognitens Cognitens WLS400A, in North America. Customers can choose between a portable configuration and an automated system, which can be operated with all common industrial robots. All Cognitens systems include the software suite Coreview, also made by Hexagon Metrology.

Coreview version 5.0 software has been configured to achieve improved utilisation of the operating system, memory management, and third-party 64-bit software. This enhancement is critical in speeding up large point cloud processing and CAD utilisation. In one case study processing time was cut by 80 per cent. The WLS400 uses digital stereo-vision technology to generate highly accurate 3D data. The automotive and aerospace industries have embraced this technology because it accelerates quality control and performs well in vibration-prone shop-floor environments.

The problem of vibration is resolved by the WLS400's ability to shoot and capture 3D surface data in less than 10 milliseconds, as compared to the competitor's rate of 1-2 seconds. Due to the ultra-fast data acquisition rate, any vibration in frequencies up to hundreds of Hz do not affect the results. The outcome is higher data integrity with no ghosting and no need to repeat measurements. Neither is the device's performance impacted by variable lighting or temperature changes.

The product comes with safe Blue Light LED technology, which enables a greater variety of surface finishes to be measured or reverse engineered. According to Hexagon Metrology, this advancement virtually eliminates the use of spray-on developers in all but the most extreme cases. The Cognitens WLS400 product line will be presented at the Hexagon Metrology Booth 1508 at the Aerodef show held in the Anaheim Convention Center, Hall D, 5-7 April 2011.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa...

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin...

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
