Scopemeter Devices Operate in Harsh Environments

Fluke has added three two-channel models to its range of handheld 190 Series II Scopemeters, which can be used on industrial equipment that is permanently fitted on an electrical distribution system. The new Fluke 190-202, Fluke 190-102 and Fluke 190-062 devices offer 200MHz, 100MHz and 60MHz respectively, a real-time sampling rate of up to 2.5GS/sec and a 400-picosecond resolution. The latest models are designed to complement the recently introduced four-channel Fluke 190-204 and Fluke 190-104 Series II Scopemeters.

Together, they are claimed to be the first oscilloscopes on the market with a 1,000V CAT III/600V CAT IV safety rating. The Scopemeters are designed for industrial plant maintenance professionals responsible for servicing, installing and maintaining heavy-duty electrical equipment, electromechanical machinery and plant automation control systems. The Fluke 190 Series II Scopemeters are said to incorporate a number of time-saving features to provide increased productivity. Connectandview triggering offers hands-free operation, providing an immediate, stable display for capturing and displaying complex waveforms for rapid fault finding.

The Trendplot recording function helps to uncover long-term trends and shows changes in any of the measurable parameters, such as the rise time of a signal. Meanwhile, Frequency Spectrum Analysis using FFT helps to identify individual frequency components contained in a signal. The Scoperecord function allows waveform recordings to be made over an extended period of up to 48 hours. Finally, the Replay function enables the user to take a closer look at any anomaly seen flashing by on the screen, by replaying the last sequence of 100 screen images. The new Fluke 190 Series II Scopemeters are designed for use in harsh environments.

The sealed casing is IP51 rated and the high-capacity lithium-ion rechargeable battery is designed for operation lasting up to seven hours, with easy access for battery switching to extend operating time. USB ports offer PC connectivity and memory device insertion. In addition, the Fluke 190-xx2/S Series II Scopemeters include an SSC kit, including a hard case and the Flukeview software for documenting, archiving and further data analysis.

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.
