PCB Vibration Switch Gets Atex Approval

PCB Piezotronics has announced that its 686B01 series vibration switch has been Atex approved for use on machinery in hazardous environments. The EX686B01 is suitable for 24/7 continuous protection of cooling tower fans and gearboxes, fin fans, motors and pumps, HVAC systems, wind turbines and other critical machinery operated in hazardous areas. Meeting Atex Ex nL IIC T3 approval requirements, the EX686B01 is hermetically sealed and mounts with a single stud, like a sensor.

This vibration switch includes an embedded piezoelectric accelerometer for accurate measurement and monitors vibration velocity for more consistent results. The EX686B01 also offers a remote reset capability and USB programmable alarm threshold and time delays to avoid false trips. PCB's EX686B01 is fully user programmable via USB and is a low-cost drop-in replacement for most popular mechanical vibration switches as it only requires two wires and can replace legacy switches without additional cable runs.

The EX686B01 is also suitable as a lower-cost alternative for many electronic vibration switch applications requiring single relay operation. All standard PCB sensors are supplied with Lifetime Warranty Plus and are also covered by the company's Guarantee of Total Customer Satisfaction.

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.
