Precision current loop calibrator saves time
The Comtest Group, Fluke’s authorisedTest
andMeasurement Distributor for South and
southernAfrica, has offer Fluke 709 and 709H
mA loop calibrators, specifically designed
to save time and produce high-quality
results. These calibrators are built around
a user-friendly interface with a Quick-Set
rotary encoder knob. This tool reduces the
time it takes to measure, or source, current
and power up a loop.The protective holster
easily fits into a technician’s hand and the
large backlit display is easy to read, even
in dark, cramped worked areas. The 709H
adds HART communications and supports
a select set of the HART universal and
common practice commands. This makes
the 709H unique as both an affordable,
compact loop calibrator and powerful HART
communication troubleshooting tool. In the
communicator mode the user will be able
to read basic device information, perform
diagnostic tests, and trim the mA output on
most HART enabled transmitters. In the past,
this could only be done with a dedicated
communicator, a high-end multifunction
calibrator, or a laptop computer with HART
modem. Fluke 709H will allow virtually any
technician to service and support HART de-
vices. In addition, the 709H offers:
• Logging of HART data in the field. Once
recorded by the 709H in the field, the
709H/ TRACK software can upload the
HART configuration of up to (20) HART
devices in your plant and output data in
either (.csv) or (.txt) format.
• Data logged mA loop measurements
and HART data can be recorded from
a particular transmitter for trouble-
shooting and loop tuning. The data log
feature offers selectable capture with
recording intervals of 1 to 60 seconds
and a logging capacity of 9 800 records
or 99 individual sessions. Each data
sample contains the 709HmAmeasure-
ment, all four process variables, and the
standard status conditions.

Earthing and short-circuiting device
with aluminium cable
When using aluminium-cable earthing and short-circuiting
devices instead of copper-cable for railway systems, switch-
gear installations or overhead lines, the advantage of the
weight-reduced cables becomes immediately evident.
The new aluminium earthing and short-circuiting device
(single-pole, 50mm² or 70mm²) from DEHNAfrica is consider-
ably easier to transport and use than conventional devices. In
the past, high copper prices led to material theft and damage,
meaning that the new earthing and short-circuiting device
with aluminium cables offers huge cost saving and conveni-
ence potential.
The new offering from DEHN Africa comes in a variety
of different models, including an earth clamp for overhead
contact lines and clamp for railway tracks with tommy bar;
an earth clamp for overhead contact lines and clamp for rail-
way tracks with ratchet; a universal clamp (T Pin Shaft) and
universal clamp (Handle); a conductor clamp and universal
clamp (Handle); ball head caps (Ø25 mm); a universal clamp
(Handle) and clamp for railway tracks with tommy bar; a
universal clamp (Handle) and clamp for railway tracks with
ratchet; and with universal clamps (Handle) on both sides.
Thus, earthing and short-circuiting kits can be fitted with
the available clamps using diverse combinations to fit the
required function.

Reliable software for multiple phase
measurement
Emerson Process Management introduces Micro Motion Advanced
Phase Measurement (APM), a software option available on the Model
5700 Transmitter. The software solution helps improve measurement
accuracy across diverse industries in challenging multi-phase applica-
tions such as direct wellhead and separator net oil measurement in the
oilfield and starch concentration for food and beverage plants.
This multiple phase measurement solution provides insight into the
complete flow stream, including oil, water, and gas, through an intuitive,
local display. Leveraging Emerson’s years of experience in providing
solutions for process upsets or intermittent two-phase flow, Advanced
Phase Measurement provides continuous, real-time production data for
oil, water and gas void fraction. “Advanced Phase Measurement was
designed with production engineers in mind, providing insight into
production trends with a single device to reduce capital and operating
expenses,” said Kevin Borden, Product Manager. “You can track whether
production is increasing or decreasing, allowing proactive management
of changing field performance which ultimately equates to more dollars
in your bottom line.” Advanced Phase Measurement has also proven
useful for the life sciences and chemical industries, providing critical
measurement insight to reduce waste, maintain product quality, and
identify process upsets even in the presence of multiple phases.
