Assess Lightning Protection Megger (Norristown, PA) has announced a new series of test leads for use with wind turbines. The unique KC series leads are long enough to be used for assessing the continuity of lightning protec- tion conductors in wind tur- bine blades. Features include: Availability in 3 lengths: 98', 164', and 328'. A heavy-duty cable reel that is fitted with a friction brake to avoid tangles. Large Kelvin clips for termination. A 16' cable fitted with a duplex handspike for probing the
lightning receptors on the tips of the turbine blades.
Omega (Stamford, CT) has
introduced a new series of pre-
wired strain gages. Each gage
for the KFH series has 50 mm
of PTFE cable before transi-
tioning to AWG 28 leads, to
prevent leads from adhering
during installation. This series is
ideal for R&D and automotive
industries where stress analysis of
suspension components are nec-
essary. Features include:
Short, medium, and long grid linear gages and short and medium
grid XY gages (T-Rosettes).
No soldering at the measuring point.
Availability with 2, 1-m leads or 3, 3-m leads.
Either 120 or 350 resistance.
A rugged polyimide carrier.
0°/45°/90° Planar Rosettes 0.6 to 6 mm grids.
Cylindrical Photoelectric Sensors
Omron Automation and Safety (Schaumburg, IL) has developed a new generation of M18 cylin-
drical photoelectric sensors that combine simple selection and installation with reliability, versatil-
ity, and rugged construction. Along with the straight-beam models, Omron also developed right-
angle radial-beam plastic body E3RA and metal body E3RB models. Features include:
Enhanced EMC protection.
Robust waterproof housings.
A bright red LED light source that is visible over long distances.
Through-beam versions with ranges up to 20 m, retro-reflective versions with ranges from 0.1 to
4 m, coaxial retro-reflective versions with ranges up to 500 mm, and 3 models of diffuse-reflective
sensors with ranges of 100 mm, 300 mm, and 1 m.
Small Profile Optical Encoder
The new RSF MS 14 encoder system from RSF Elektronik
(Austria) is a frictionless kit style encoder for motion
signal status LED.
A high contrast
of ± 5 and ± 15 µm
depending on scale tape mounting method.
A grating period of 40 µm for analog systems (for digital systems,
signal periods from 2 microns down to 100 nm are available).
