TDK (Uniondale, NY) has announced the CCT series of clamp AC
current sensors rated to 30 A and 100 A, respectively. They are suitable
for power distribution panels in a variety of energy management systems.
■ A snap-on clamp design.
■ An integrated open-circuit protection element for voltage peak
■ Max output currents of 10 mA ( 30 A) and 33. 3 mA (100 A).
Pepperl+Fuchs (Twinsburg, OH) has
announced the FieldBarrier R4D0-FB-IA, a diagnostic-enabled
isolated device coupler for FOUNDATION Fieldbus H1 and
PROFIBUS PA instruments. Features include:
■ Fault protection at the spur which isolates conditions such as short
circuit, jabber or bounce.
■ Advanced diagnostics that detect installation quality issues for
optimum segment availability.
■ Internal components connected without wiring.
(Hampton, VA) now offers the
LL-01 Sentio Series of miniature
ultrasonic liquid level switches that
combines ultrasonic technology with analog
circuitry to measure aerated liquids. The rugged, 316L stainless
steel sensors are not affected by the dielectric or optical properties of liquids. The series detects liquid levels in space-constrained
applications, such as fluid storage tanks, compressors, boiler tanks,
hydraulic reservoirs, and chillers. Features include:
■ Ultrasonic technology for measurement of aerated liquids.
■ A repeatability of 2 mm or better.
■ A standard relay output of 0.5 A SPST.
■ The ability to handle pressures of 250 psig standard; up to
500 psig available.
■ An operating temperature range from - 29° to +80°C.
Process Sensors (Franklin Lakes, NJ) has introduced its self-contained pyrometer models, the stand-alone
PSC-SR54N and PSC-SR54NV. With temperature ranges spanning from 500° to 3,000°C, the new
models offer a choice of integrated red laser or video camera sighting. Features include:
■ High resolution fixed focus optics with small spot sizes.
■ A digital RS485 communication interface.
■ An analog 4 to 20 mA output.
■ A rugged stainless steel housing.
■ The choice of obtaining output signals from shorter or longer wavelengths, or both via
analog and serial communication ports.
Megger (Norristown, PA)
now offers a handheld
time domain reflectometer
(TDR) that locates faults
on mixed paired metallic
cables. The CFL535G can
test the capabilities of connections and locate faults
for up to 12 miles ( 20 km).
It also allows technicians to
compare cable pairs to each
other and determine if one is faulty.
■ Dual channel capability and dual aspect display.
■ An ultra-fast 2 ns pulse width.
■ 2 inputs for simultaneous measurements of 2 different cables.
■ An auto set-up mode for instant use.
■ A large, color, high-resolution, fully adjustable backlit display.
■ Bed-of-nails test leads.
■ 5 output impedances.
■ An operating temperature range from - 15° to +50°C.
