How Loud is 90dB?

This has always been a tough question to answer. Chris in our technical department recently sent me a link that helps explain it!

This is a common question when customers are looking at ordering piezo buzzers or adding an audible alarm to a light tower.

Noise Decibel Level   Notes
Jet take-off at 25 meters 150 Eardrum rupture
Thunderclap, chain saw 120 Painful
Power mower 96 Likely damage after 8 hours exposure
Vacuum cleaner 70 Most people would find this annoyingly loud
Background music 60 Fairly quiet
Library  40 Very quiet
Breathing 10 Barely audible

WEG Electric Introduces Its Newest Line of Open Induction Motors-W40

WEG Electric is releasing its newest line of open three phase induction motors, available with standard frame sizes from NEMA 254T to l6808/09.  Key features of these newly designed motors are their competitive cost, highly efficient cooling and lightweight and compact construction.  In most applications at least one frame size small can be specified over  a TEFC motor.  In addition, for applications where the elements are a factor the W40 can be specified with WPI or WPII levels of environmental protection depending on the frame size.

This new motor design can be used in compressors, blowers, oil well and fire pumps and industrial refrigeration applications.  All models meet or exceed NEMA standards as well as international efficiency requirements.

The ODP version of this new motor is an effective option for applications which do not need a high level of protection from the elements.  Due to its open enclosure and new motor design it can achieve higher output levels when compared with TEFC motors.  The result is a cost effective solution for driven equipment.

W40 motors come standard with ball bearings, grease nipples, Class F insulation and are suitable for inverter operation up to 460V. Optional features include roller bearings (sleeve bearings above L5810), space heaters, an accessories terminal box, thermal protections, Class H insulation and are suitable for inverter operation above 575V.

Distance Measurement with Pepperl + Fuchs

The VDM28 distance measurement sensor offers precise technology in the smallest housing at an incredibly low price.

Marshall Wolf Automation, your full-line industrial automation distributor, is an authorized Pepperl + Fuchs distributor.

Determining distances is one of the most common metrological applications in automation technology.  The market supplies many set solutions, yet not every technology is ideal for each application.  The VDM28 distance sensor is setting standards in this dynamic field.

With a measuring range up to 8 meters, the sensor reliably detects distances in diffuse mode.  The groundbreaking Pulse Ranging Technology (PRT) measuring principle is used.

For the first time, a red laser emits short light pulses to determine distance by measuring the time of flight of the reflected pulses.  The highly visible beam also enables optimal alignment.  In contrast to other procedures, measuring accuracy is independent of object surface.  The measuring principle eliminates issues such as detecting "phanton objects" or measuring fluctuations due to ambient conditions.

  • Additional special features:
  • High repeatability
  • Extremely fast (10 ms)
  • Minimal black-white difference
  • Immune to extraneous light
  • IO-Link interface

Please visit our website at www.wolfautomation.com and view a sampling of our huge product selection.  In addition to sensors, we offer a variety of variable frequency drives, gearboxes, industrial light towers, and a large variety of specialized industrial automation equipment.

Werma 740 Incandescent Stack Lights, Explosion Protected

Zone 1 and 2, Zone 21 and 22!
Tower in flame-proof enclosure.
For hazardous locations due to gases and/or dusts. 

The Werma 740 Series has all the advantages of a stack light and are now available for hazardous locations. Attention-getting visual features can be safely signaled in areas susceptible to the collection of hazardous gases and dusts. Visual communication and text messaging a machines status is clearly provided via leading technology.

Typical applications include Machines and equipment in hazardous areas due to the presence of gas or dust: petroleum refineries, chemical plants, waste water treatment plants, pharmaceutical manufacturing areas, grain silos, paint spray booths, etc.

WERMA signal horns, electronic buzzers, flashing beacons, double flash beacons, signal towers and horns, and rotating beacons all in explosion proof housings. With the optical portion, the relative importance of the action to be taken can be indicated by color as well as by the light effect and length of the signal being used.

The customer can choose from a whole spectrum of signals ranging from the permanent light to the more intensive blinking light through the rotating indicator or the attention-getting flashing light. While the audible portion is where caution, prudence and clarity are essential, these signals are used to indicate emergencies and demand direct action. They are understood throughout the world regardless of culture or written language. Signaling with audible devices works via one or more tones or tone sequences.

 

BENEFITS
•Customize exact solution for exact application
•Low maintenance due to LED design
•Machine vibrations will not shorten bulb life
•No need to remove equipment indication to safe areas. 740 series allows signals to remain on the equipment.

Division 2 or Zone 2 area

This is a step up from the safe area. In this zone the gas, vapor or mist would only be present under abnormal conditions (most often leaks under abnormal conditions). As a general guide, unwanted substances should only be present under 10 hours/year or 0–0.1% of the time.[citation needed] Division 1 or Zone 1 area. Gas, vapor or mist will be present or expected to be present for long periods of time under normal running. As a guide this can be defined as 10–1000 hours/year or 0.1–10% of the time

Zone 21

A place in which an explosive atmosphere in the form of a cloud of combustible dust in air is likely to occur in normal operation occasionally.

Zone 22

A place in which an explosive atmosphere in the form of a cloud of combustible dust is not likely to occur in normal operation, but if it does occur will persist for a short period only.

WEG Electric Introduces the CFW500 Machinery Drive

WEG Electric introduces the new CFW500 variable frequency drive loaded with features machinery designers, OEM's and end users want.

The VFW500 is the most recent addition to WEG's complete line of variable frequency drives.  WEG's engineers specifically designed this new drive with increased features that focus on the machinery manufacturer's needs.  It is simple, efficient, flexible and can be commissioned quickly and easily.

Marshall Wolf Automation, your full-line industrial automation distributor, is an authorized WEG distributor.

Some key features of the CFW500 include V/Hz and vector control operating modes, a built-in PLC, integrated keypad with back lit display, optional external flash memory module, and 'plug and play' option modules for communications and I/O to accommodate numerous machine configurations.

The CFW500 is designed to operate in ambient temperatures up to 50°C and can supply an overload of 150% for one minute, repeatable every 6 minutes without derating.  This capability eliminates the need for the machine designer to oversize the VFD.

In addition, the CFW500 is designed to follow a pulse train signal as its speed reference and also transmit a pulse train through its digital output making it ideal for master/slave or matched speed applications.

The built-in fully programmable Soft PLC is ideal for managing an OEM's machine logic control needs.It includes a P-I controller for control loops, a sequencing control for progressive machine processes along with numerous logical functions, eliminating the need for an external PLC.  The programs saved in the CFW500 memory can also be password protected to secure the OEM's intellectual property.

Marshall Wolf Automation has a very user-friendly website at www.wolfautomation.com. The website displays a sampling of our huge product selection.  In addition to variable frequency drives, we offer a wide selection of power supplies, industrial tower lights, contactors, and sensors, just to name a few categories.
