inating the need for motor load sensors.
The Fluke 438-II simplifi es the process
of motor performance diagnosis by pro-
viding analysis data for both the electri-
cal and mechanical characteristics of
the motor while it is in operation. Using
proprietary algorithms, the 438-II mea-
sures the three-phase current and voltage
waveforms and compares them against
rated specifi cations to calculate motor
mechanical performance. The analysis is
presented in simple readouts, making it
easy to gauge the operating performance
and determine if adjustments are need-
ed before failures cause an operational
shutdown. The analyzer also provides
measurements to determine a motor's
effi ciency and mechanical power under
operating load conditions. These mea-
sures allow maintenance engineers to
determine the motor's in-service operat-
ing power compared to its rated power
to determine if the motor is operating in
overloaded condition or, inversely, if it is
oversized for the application.

Defl ection Elbows Now
Available in Cast Aluminum
The cast aluminum line of Smart Elbow
defl ection elbows from HammerTek is
now offered in tube and pipe sizes from
1.5 in. (3.8 cm) up to 12 in. (30.5 cm)
in diameter. Engineered for dilute-phase
and dense-phase pneumatic conveying,
the defl ection elbows prevent miner-
als, aggregate, sand, iron ore, and other
abrasive materials from impacting the el-
bow wall, and causing wear, failure and
downtime. The elbows feature a spherical
chamber that protrudes partially beyond
the desired 90º or 45º pathway, which
causes a ball of pellets suspended in air
to rotate, gently defl ecting incoming ma-
terial around the bend without impacting
the elbow wall or generating heat. Other
defl ection elbows, offered in varying size
ranges up to 18 in. (45.7 cm), are avail-
able in cast iron, carbon steel, stainless
steel and specialized alloys.
