HOW DO I KNOW
IF I’M TALKING TO
AN ENGINEER OR
Ask Smalley. It’s simple to tell
when you work with Smalley. That’s
because you’ll always collaborate
directly with our world-class team
of engineers—experts whose only
focus is helping you get the most
performance from your precision
wave springs or retaining rings.
Smalley wave springs reduce spring
operating height by 50%, saving space
spaces. We offer more than 4,000
stock sizes in carbon and stainless steel.

THE ENGINEER’S CHOICE™
NK Technologies (San Jose, CA) has
introduced the AT/ATR-MS Series AC
Current Transducer, combining a current
sensing element and signal conditioner
into a single package. The large split-core
design allows for installation over existing
conductors without the need to disconnect
the load, even in applications with multiple
conductors per phase. Features include:
■ An industry standard output of 4 to
20 mA, signal proportional to the AC
■ A loop powered design.
■ A sensing window, which provides
space for bus bar, single, or multiple
■ Factory calibration.
■ UL, CUL, and CE approval.
Jewell Instruments (Manchester, NH)
has announced the A601-2 tiltmeter
series as the latest installment to the
electrolytic sensor family for geophysical
and geotechnical applications. The model
replaces the 520M geodetic platform
tiltmeter. Features include:
■ A dual-axis sensor with built-in
micrometer leveling legs.
■ An absolute gravity referenced electrolytic
■ Precision of up to < 25 nanoradians with
virtually no thermal drift.
■ High and low gain ranges offered with
outputs of ± 8 DC voltage (single-ended)
and ± 16 VDC (differential).
■ An IP50 seal rating.
