Zumbach Electronic AG has recently extended its range of
Steelmaster rod and bar gauges with a further and larger model.
The new gauge, SMO 160-S6, is equipped with six high-speed
laser scanners ODAC® 160 and delivers up to 6,000
measurements/s ie 1,000 processed profiles/sec. It also features
Zumbach’s calibrated single scan system (CSS) and the unique
EPM method and software.
The gauge is able to measure rounds, hex, squares, flats and
various shapes with outside dimensions up to approximately
140mm (depending on product vibration) in multiple modes:
• Static, orientable mode: measures in six directions, 30 degrees
spaced
• Partial oscillation mode: programmable start and stop angle,
eg for squares or flats
• Full 180° oscillation: standard mode for rounds, every 30°
rotation delivers a full profile
The new EPM method and software, in combination with CSS,
makes the gauge a very effective tool at three roll blocks or
when the bar has polygonal or asymmetric shape deviations, eg
asymmetric underfill or overfills. It calculates the typical values
DT and GT for the initial roll settings.
It can also calculate and displays “Roundness” RON t according
the official ISO definition for any shape.
The mechanical system is the same as the well proven design
of the smaller gauges and requires minimal maintenance and
periodic cleaning only.
Smaller gauge models for wire rod and smaller sizes are also
available.

Two high-performance vinyl jacketing
compounds from Teknor Apex withstand
the harsh cold, exposure to lubricants, and
other challenging conditions encountered
by control and power cables within the
nacelles atop wind turbine towers.
Drawing on its expertise in compounding
elastomeric materials, Teknor Apex
has taken two different approaches to
meeting the rigorous requirements of
wind turbine applications:
• Flexalloy® 9609-80 is an 80 Shore A
PVC-based elastomer that provides
superior long-term UV resistance. It
exhibits a brittle point of -60 ºC.
• Apex® N-56001 is a 76 Shore A blend
of PVC and nitrile rubber that provides
superior long-term low-temperature
flexibility and oil resistance. It exhibits
a brittle point of -54ºC.
Besides exceeding application standards
for impact resistance at temperatures
down to -40ºC, both compounds pass
required tests for UV resistance, 60-day
oil aging at 75ºC, and flammability
performance as specified in UL 1685-F4.
The two compounds are rated at 105ºC
for maximum continuous operating
temperature.
“Teknor Apex has developed Flexalloy
9609-80 and Apex N-56001 to provide
cable manufacturers with different
options for meeting application
requirements,” said industry manager
Mike Patel.
“Both products are high-performance
alternatives to the standard flexible
vinyl compounds used in cable
jacketing and are particularly valuable
for their cold-impact and oil-resistance
properties.”
