Singula Now Handles Lossy Materials

Integrated Engineering Software has announced that the latest version of its Singula product for antenna analysis now handles highly lossy materials. Singula simulates the power loss that occurs as a result of the heat generation produced when lossy materials are exposed to electromagnetic waves The loss calculations can then be used by thermal analysis software to calculate the thermal distribution. Integrated's simulation software tools have been developed for engineers and scientists who design and model prototypes and need fast and reliable solutions.

Utilising computer simulation during the design process helps reduce the cost and risks associated with physical prototyping. Singula analyses all antennas including wire, surface and dielectric. RFID devices and bird cage coils for MRI applications are also modelled using this simulation tool. Other applications for Singula include scattering calculations, microwave circuits and shielding for Electromagnetic Compatibility and Interference (EMC-EMI).

Singula is a generalised hybrid method that combines the Method of Moments (MOM) with Physical Optics, and the Fast Fourier Transform (FFT) method to give engineers the option to choose the solver that best suits their needs. Engineers can select the MOM technique for midsize antennas, FFT for antennas requiring many wavelengths or, in special cases, such as reflector antennas, the combination of Physical Optics with MOM maybe preferable. Bruce Klimpke, technical director at Integrated, said: 'There are many applications that will benefit from the accurate handling of highly lossy materials, including stealth technology.

'In the military this technique is used with aircraft, ships and missiles to make them less visible to radar and other detection methods. 'In the biomedical field, an example would be an antenna radiating in the presence of highly lossy materials like biological matter, such as the antenna in a mobile phone.' Integrated's team of engineers and software professionals designed Singula to help solve a wide variety of high frequency electromagnetic field (EMF) problems.

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.
