RFID-sensor combination

RFID technology makes it possible to identify goods and substances with the help of electromagnetic waves within certain frequency ranges. HARTING regards UHF RFID technology as the right choice for the transportation, automation, machinery and energy markets. This technology stands up to the harsh environmental conditions that prevail in these markets and also reliably registers rapidly moving objects with metal surfaces, such as railway cars. A read range of from 5 cm to 12 m ensures the greatest flexibility for the applications.

Thanks to its special patented transponder properties, the HARTING portfolio is optimally suited for these conditions. The High Performance Reader, which is capable of registering and processing more than 300 transponders per second, is joined by a selection of reading antennas. These allow HARTING to offer modular solutions for the widest range of applications in the RFID field.

In the age of the "Internet of Things" in which goods or even living beings are represented in a virtual Internet structure, UHF RFID is one of the most interesting interfaces. The next logical step in this context is the integration of sensors into passive transponders to enable goods to register additional information about their environmental conditions such as the temperature. This also means an additional step forwards for today's software architecture as industrial processes will achieve a higher level of automation and become more transparent and controllable.

At SPS/IPC/Drives HARTING will be presenting a passive UHF transponder with temperature registration implemented in a real application that demonstrates data acquisition and visualization in a Web interface.

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.
