The
Examiner
1000 is a hand-held, battery-powered overall vibration meter. It is
the perfect tool for trending overall vibration readings in process
equipment such as : Rolling element bearings, Motors AC/DC,
Pumps, Gearboxes, Compressors and Fans.
VISGAGE
checks oil viscosity on-site; without
thermometers or stop watches. The VISGAGE can be used to check any oil
from a light spindle oil to heavy gear oils.
The HA-2 complete REACT
Shaft Alignment System is the most cost-effective and
efficient machinery alignment system available anywhere. The REACT
System combines the most versatile and sturdy stainless steel
hardware in the industry . You can perform both the "Rim/Face"
method as well as the "Reverse Indicator" method with the same
hardware. The system accommodates shafts from 1/2" to 9-1/2"
and includes all the necessary hardware, clamps, chains, etc. all packed
in a sturdy aluminum carrying case

| Question:
"How can acoustic analysis be useful
in my maintenance program?"
Answer:
Acoustic analysis has many uses in a PdM program. It has
been an element, along with more “traditional” vibration measurements
such as velocity and acceleration readings, in determining machine bearing
condition. The most dramatic and immediately gratifying use of acoustic
analysis in locating pneumatic and steam leaks. The traditional approach
for pneumatic leakage location has been the “Souper Snooper” soapy
water solution approach. This is effective, but highly manpower intensive
and can be quite messy and slippery. Acoustic signals are generated by
these leaks and a hand held device can be used to quickly locate leaks
without using solutions. This leakage location method can even locate
leaks found among other audible sources. It will seem amazing to find a
leaking tubing that is surrounded by very loud machines. This tool can
eliminate an entire crew of technicians.

Note: Ultrasonic Inspection |

Air Leaks: Do your compressors run when
your plant is unmanned? Do you have difficulty maintaining optimum
pressure? Do you rely on your backup compressor to meet routine demand?
Save thousands in energy cost by repairing air leaks. Ultrasound is the
easiest way to find them, especially with the Accutrak VPE-1000.

Steam Traps & Valves: Leaking
steam traps are tremendously inefficient. Bad steam traps are surprisingly
common, roughly 30% of the traps in a plant with no trap testing program
will be leaking! Use a contact probe to hear the internal flow through
steam traps and valves.
Bearings: Using Ultrasound to identify
bearing wear in its early stages can be a valuable tool in avoiding costly
downtime. As internal components in moving machinery begin to wear,
increased friction creates subtle changes in the ultrasonic sound
being generated. These changes in ultrasound present themselves before
other signs like heat or vibration are noticeable.

| What's
Hot? (...and less than $1,000.00) |
|
The AccuTrak®
VPE-1000 Ultrasonic Inspection system is extremely sensitive to the
ultrasonic sound of leaks and friction in industrial systems. So sensitive
the VPE-1000 can hear the blink of an eye, yet most background noise will
not interfere with detection accuracy. Use the VPE-1000 for a variety of
leak detection and plant maintenance applications such as : Steam Traps,
Bearing Wear, Valve Testing and Air, Vacuum, Refrigerant and Gas leaks.
The Monarch Pocket-Tach
Plus Kit is a 3 button, 30 function contact/non-contact digital
tachometer, totalizer/counter and timer (stop watch). It will measure RPM
and English/Metric linear speed.
The CMCP1000
is a dual limit, single channel Vibration Monitor with an integral
accelerometer packaged in an explosion-proof housing suitable for NEC
Division I hazardous areas. Designed to comply with API670 standards, the
CMCP1000 far exceeds the capabilities of competitive vibration switches.
The unit also provides a buffered transducer output for detailed
diagnostics. The CMCP1000 a local display in terms of velocity with
a full scale range of 0 to 1.0 in/sec.

Vibration Transmitters are gaining usage. Here is a comparison of two
popular transmitters. A review indicates that the CMCP500 series
transmitter offers a better quality , lower cost product that draws less
current, and provides higher accuracy.

| Case
History: |
A mid-west Utility wanted to upgrade their obsolete IRD continuous
monitoring system on their Boiler Feed Pumps. In lieu of a traditional
rack mounted supervisory system, we provided a modular, distributed
approach utilizing CMCP500
series transmitters and monitors, which significantly lowered both
the component and installation cost for the project. Eddy Probes were
used to replace Shaft Riders for radial vibration and were also
installed for axial position measurements. If you have an outdated rack
mount system, give us a call to discuss how we can assist you in
providing a cost effective distributed monitoring system at a fraction
of the cost of traditional monitors.

Schedule: |
| The Reliability Direct, Inc. offices will be
closed December 25, 2000 through January 1, 2001. Orders may still be
placed on our secure internet website during this timeframe, and message
and e-mails will be promptly answered. From the RDI family to yours,
here's wishing you a safe and happy holiday season. |

Many Thanks to all of you who participated in last issues' Trivia
Contest. With about 100 correct answers from participants, the
names were placed into a hat and our accountant, Natalie Henderson, drew
the winning name. Larry Wright of M&M Mars was awarded a $50.00 gift
certificate that may be redeemed at any member of the Pappa's Restaurant
Chain.
Question
#5 Ultrasonic leak detectors
"hear" leaks, therefore the sensitivity can not be accurately
stated in terms of cc/sec, parts per million, or ounces per year. The
proper specification for these types of detectors is ____(?)_____.
