Photonfocus Releases Pixel Professor Smart Camera

Photonfocus, a manufacturer of CMOS industrial cameras, has brought out the Pixel Professor CMOS Smart camera, featuring on-camera image pre-processing. The pre-processing in the camera enables the design of machine vision systems with distributed intelligence. Performing pre-processing on the camera reduces the vision system computer CPU load, meaning the vision system can run faster or use more sophisticated algorithms in the same time period, producing better results. The technology is scalable and can be fitted to a customer's application.

The Pixel Professor supports common image pre-processing operations in pipelined processors, such as convolution and non-linear filters, histograms, erosion and dilation, adaptive thresholding, image buffers, image arithmetic, colour space conversion, look-up tables (LUT), triangulation and others. Setting up the pre-processing unit on the Pixel Professor is made easy with a simple graphical user interface (GUI).

It allows for control loops and multiple passes. Customised operators can be implemented alongside standard operators. Alternating frame capture setups can be realised with an embedded sequencer to achieve maximum frame rates.

In-built pre-processing hardware in the camera removes the reliance on specialised frame grabbers or other hardware accelerators. The Pixel Professor cameras output pre-processed images via USB 2.0 or Gige. No frame grabbers are required. The benefits of the Pixel Professor cameras include: reduction of pre-processing time, which increases frame rate; enhanced algorithms with same CPU-load compared to software image processing; and real-time processing of up to 640 Mega pixel per second (Mps).

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.
