The
hand-held
ALL-TEST PRO™ 31 incorporates tests for faults to ground, internal
faults such as turn-to-turn and coil-to-coil and phase balance. Electric
interference from residual or stray currents from test-object or
surrounding power sources is measured by an included EMI test.

Intrinsically Safe PDA's:
Light, ergonomic and ruggedized - optimized for high
productivity! The i.roc x10 -Ex is a high performance industrial PDA
with compact external dimensions based on Windows Mobile™ with an
integrated WLAN 802.11b, Bluetooth™ and an IrDA infrared port. To meet
the diverse needs and requirements of industry both inside and outside
the ex-area, the i.roc x10 -Ex is available in three different
versions.
-
Humidity, Air Temperature plus IR for non-contact
Temperature measurements!
Now you can measure Humidity and Temperature in factories, clean rooms,
offices and green houses - all with one hand-held instrument.
Non-contact infrared surface temperature measurements for
electrical service, and hard to reach areas such as heating and air
conditioning ducts.

Ask The Expert: Advantages
of Proper Shaft Alignment |
Shaft misalignment costs time and money
Shaft misalignment is responsible for up to 50% of breakdowns in rotating
machinery. Those breakdown cause increased machine downtime, which
translates directly into higher costs. Additionally, incorrect alignment
places a greater load on machine components, resulting in increased wear
and tear.
Effects of misalignment on bearing performance
Misaligned shafts generate a moment, which creates a reaction force in the
shaft bearings of the driven and drive units. Care should be taken to
ensure the degree of misalignment between the shafts is within the
coupling manufacture's tolerances and the machinery manufacture's
recommendations. A 20 % increase in load caused by misalignment will
reduce the calculated bearing life by almost 50 %. Other serious effects
can be wear and tear of the seals, allowing contamination to enter the
bearing and lubricant to leak. Other important effects of shaft
misalignment are excessive vibration and noise as well as increased energy
consumption.
Misaligned shafts can cause:
Increased bearing load
Reduction in bearing life
Increased seal wear
Increased vibrations
Increased noise
Increase in energy consumption
Correct shaft alignment will minimize these
effects.
What exactly is
misalignment?
Misalignment occurs when the centre lines of rotation of two machinery
shafts are not in line with one another. There are two types of
misalignment: parallel and angular. In most cases, machine misalignment is
actually caused by a combination of these two types.
Advantages of
proper alignment
Longer bearing life
Minimal stress on couplings, reducing the risk of overheating and breakdowns
Minimal wear of seals, lowering risk of contamination and lubricant leakage
Lower energy consumption
Minimal vibration and noise
Increased uptime

The
Consulting Caddie
is a balancing calculator which answers the questions that all
professional machinery maintenance personnel have when on the job and
under pressure.
-
The
Powerline L80 Pulley Alignment Tool
shows parallel and
and angular pulley misalignment.
Minimize excessive vibration, premature belt wear This system is not a
computer and there is no programming. Allows a single craftsman to
perform precision pulley alignment.
-
The
OilCheck extends your oil drain intervals - it detects and measures
the dielectric constant of oil. By comparing the measurements obtained
from used and unused oils of the same brand, the OilCheck is able to
determine the degree of change in the condition of the oil.
