Fluke Updates Multimeter For Rail Applications

Fluke has introduced the 287/TPWS datalogging multimeter, for rail applications, in the UK. In addition to the wide functionality of the Fluke 287, this model also provides testing of the red-signal Train Protection and Warning Systems (TPWS), meeting the requirements of Network Rail with Certificate of Acceptance PA05/03684.

The accuracy of measurement provided by the Fluke 287/TPWS is vital when checking the strength of signal from the static transmitter, placed between the rails, as detected by an on-board receiving aerial. The Fluke 287/TPWS provides simultaneous readouts of different measurements, such as true-RMS AC and DC amps and volts, frequency, dB and more. The interface ensures data transfer to a PC, on which optional Flukeview Forms software allows users to document, store and analyse readings, and then convert them into meaningful graphs and tables for professional reports.

The Fluke 287/TPWS set-up is customisable to save time and increase productivity. Multiple save options and automatic time stamping allow convenient recall of field measurements. Peak capture can record transients as fast as 250us. A relative mode removes test lead resistance from low ohms or capacitance measurements. The Fluke 287/TPWS has Cat IV 600V/Cat III 1,000V safety ratings and comes with a lifetime warranty.

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.
