FlexProbe ® - Flexible AC Current Probe

CHAPTER 2
PRODUCT FEATURES
2.1 Description
The FlexProbe
®
is a flexible AC current transformer composed of a flexible
sensor and an electronic module. The flexible sensor permits measure -
ments 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
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 FlexProbe
®
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;
600V CAT IV. The FlexProbe
®
meets EN 61010-1 and is CE marked.
The FlexProbe
®
has a mV output proportional to the current measured
for direct readings on DMMs, data loggers, oscilloscopes, and power or
harmonic meters. TRMS measurements are taken when connected to a
TRMS meter. The FlexProbe
®
is insensitive to DC currents and only the AC
component of the measured signal is measured. The sensor length is 24".
