Data Analyser Enables Multi-Channel Noise Testing

Bruel and Kjaer's LAN-XI Module Type 3053-B-120 12-channel data analyser enables multi-channel noise and vibration testing. With each module measuring 132.6 x 27.5 x 250mm, the 3053-B-120's frequency range from DC to 25.6kHz makes it ideal for a range of acoustic and vibration measurements, including structural measurements on large structures such as wind turbines.

The high-frequency bandwidth also makes it suitable for sound power measurements, such as those made to international standards ISO 3741 to ISO 3743 (comparison method) and ISO 3744 to ISO 3746. As part of Bruel and Kjaer's LAN-XI measurement hardware range, Type 3053-B-120 is said to be almost infinitely expandable with other LAN-XI input, input/output modules and mounting frames.

It's also a key building block for high-density, high-channel count systems, such as those for array acoustics and noise-source identification. When used in an array system, the module's detachable connector panel allows it to be fitted into a LAN-XI frame with a multi-pin connector to reduce the number of cables.

The same modules can also be removed from the frame and fitted with the standard 12 SMB connector panel to create individual 12-channel systems. This allows the same measurement hardware to fulfil multiple testing roles - a high-channel system, a small portable field recorder or front-end. The Type 3053-B-120 can be upgraded to a standalone recorder to allow high-quality data recording in situations where a normal PC could not survive, such in-flight, in-vehicle testing or other harsh or restricted environments.

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.
