Trac Installs Shaker System at Warwick Facility

Trac, a test and certification specialist, has increased its range of environmental test services with the installation of a new vibration test system - or shaker - at its Warwick facility. This latest addition to its test offering will allow the company to deliver an even wider range of specialist stress tests, especially to the aerospace and automotive sectors. Trac's latest investment is a Model V8-440T from LDS, part of Bruel and Kjaer.

It is a guided slip table-format vibration test system with a capacity of up to 700kg and two interchangeable table sizes that provide maximum flexibility in mounting test subjects. The system can generate forces up to 66kN over a frequency range from DC to 2.5kHz, subjecting units under test to accelerations up to 140g. The new shaker is Trac's first system that can produce displacements of as large as 63.5mm and brings the total number of vibration test systems in the company's various facilities to 15.

The LDS V8, as well as being a versatile shaker that can perform a range of screening and qualification testing, extends the company's services in several directions. The combination of large displacement and wide-duration shock pulses matches specific requirements in the aerospace industry, according to Trac. The investment will extend the company's vibration and shock testing services for electronic assemblies, including ruggedised military and avionics systems, satellite components and general product and packaging evaluation. The new LDS V8 system is installed in a custom-built soundproof cell at the Warwick site.

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.
