Transducer Fits Cylinders Handling Extreme Loads

Balluff has introduced a high-pressure-rated rod-style transducer with a working pressure of 1,000 bar for hydraulic cylinders handling extreme loads. Micropulse CD transducers ensure that extreme loads are controlled and precisely moved. They are based on the proven magnetostrictive distance-measuring technology. With an absolute and non-contact measuring principle, it is suited for reliable, highly precise and dynamic measurement of the piston position in hydraulic cylinders.

The special flange and rod design, as well as the especially stable stainless-steel material, guarantee the Micropulse CD transducer for use as a feedback system in demanding applications. The Micropulse BTL CD transducer, which is independently certified by MPA University in Stuttgart, is available with stroke lengths from 25 to 2,000mm. Able to withstand pressure peaks of 1,350 bar, the transducer outer rod has diameter of 12.7mm, an outer wall thickness of 3.25mm and is manufactured from HP160 stainless steel. Analogue current and voltage outputs are available, plus digital pulse, SSI, Profibus and CANopen interfaces.

The transducer is also the first such system to achieve an EX rating for zone 2, ignition class nA. The BTL CD has all the advantages of the Balluff Micropulse 600-bar rated transducers. These transducers are suitable for applications that require a high degree of reliability and precision. Suitable for measurement lengths between 25 and 7,500mm, Micropulse displacement systems are extremely versatile. The non-contact working principle of the systems ensures a complete absence of wear and a virtually endless service life.

The high-precision output signal serves as an absolute signal for the controller in a range of different interfaces. The BTL CD is aimed at the construction, offshore and specialist machinery (forging presses, lift and hoist technology) markets.

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.
