S-2000AN Isolator Measures Small Magnetic Fields

Newport has introduced the S-2000AN Stabilizer Non-Magnetic Vibration Isolator. The S-2000AN is suitable for applications where the measurement of small magnetic fields would otherwise be impacted by traditional magnetic-steel isolators. It provides a 1Hz vertical-resonant frequency, a vertical-isolation efficiency of 98 per cent at 10Hz and a load capacity of 2000lb (907.2kg). It is suitable for isolating optical tables such as Newport's RPR-N tables or platforms, which support large vacuum chambers or other heavy instruments used in materials-research applications.

Newport has quantified the magnetic impact of the S-2000 Stabilizer isolators, allowing customers to understand their required level of performance and potentially save thousands of dollars in equipment costs. Warren Booth, product line manager at Newport, said: 'In extreme applications where it is essential that all magnetic materials be removed, the S-2000AN is the best choice due to its aluminium and 316 SS construction. 'In our tests, our AN version induced only a 1.2nT change in measured magnetic field over a distance of 0 - 2ft (0 - 609.6mm).

'This compares with more than a 35nT change for traditional magnetic-steel isolators. 'Our standard S-2000A induced a 4nT change in the measured magnetic field, which means for some "non-mag" applications, our standard S-2000A may provide sufficient magnetic immunity, allowing our customers to save nearly USD10,000 (GBP6,680) on isolation equipment compared with competitive offerings,' he added.

In addition to superior isolation performance and quantified magnetic impact, the S-2000AN features Newport's Safelock mounting clips, which secure the isolators to the bottom of any Newport optical table, improving the performance, stability and safety of the system. Available in several popular heights ranging from 16 - 28in, the new vibration isolator is equipped with precision pneumatic re-levelling valves and float-height indicators.

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.
