The LongLife AmpFlex® is a flexible
AC current probe composed of a
flexible sensor and an electronic
module. The flexible sensor permits
measurements on conductors where
standard clamp-on probes could not
be used. In particular, it can be installed
in tight spaces, around breaker panels,
around cable bundles, around wide or
large bus bars, or even wrapped
around irregular shapes. The Shape
Memory feature enables the user to
“pre-shape” the sensor, somewhat,
before inserting it between or around
conductors. This feature facilitates
closing, enhances user safety, and
alleviates the drooping effect typically
associated with flexible sensors.
The LongLife AmpFlex® is lightweight.
It does not use magnetic cores like
standard transformers. The transformation
principle is based on an air
core. It presents virtually no load to
the system under test, has a low
phase shift and excellent frequency
response, and cannot be damaged
by overloads. The sensor assembly
is waterproof and insulated for
1000V Cat. III.
The LongLife AmpFlex® has a mV
output proportional to the current
measured for direct readings on DMMs,
data loggers and oscilloscopes. TRMS
measurements are taken when
connected to a TRMS meter. The
LongLife AmpFlex® is insensitive to DC
currents and only the AC component
of the measured signal is measured. |
