GFUVE Q20B Clamp On Current Transformer for Permalloy Multimeter
Current Clamp 240A Input Large Jaw Opening
Ratio 1000:1 Split Core Permalloy Current Sensor Manufacturer
Accuracy 0.5%
In electrical and electronic engineering, a current clamp. Q20B-2
is an electrical device having jaws which open to allow clamping on
a conductor. This allows measurement of the current in a conductor
without the need to make physical contact, or to disconnect it for
insertion.
The model Q20B-2 openable jaw current sensors are best-in-class
device for use with power meters, power analyzers and DMMs. Ratio,
class, all can be customize if you have other parameters.
Current probes are key to the successful design of electrical
devices, testing instruments, and electronic parts. Probes work
with testing devices are ideal for measuring currents with high
accuracy making them indispensable tools for evaluating current
consumption and control current. In recent years, customers are
seeking current probes with high sensitivity to increase the
accuracy of design and verification. GFUVE offers wide range of
current sensors.
The Probe outputs current or voltage signal directly proportional
to the measured current, thereby providing current measuring and
displaying capabilities to instruments with low current or voltage
inputs.
GFUVE Current transformer clamp meters are equipped with rigid jaws
of made of ferrite iron. The jaws are individually wrapped by coils
of copper wire. Together, they form a magnetic core during
measurements. Their basic operation is like that of a transformer.
It works with one primary turn, or winding, which in nearly all
cases is the conductor .
The Amprobe Q20B current clamp probe measures AC or DC current
without touching or interrupting the circuit. The clamp has two
jaws that fit around a 1.0" (20 mm) conductor to convert a
high-current signal to a low-level millivolt signal so it can be
read by a testing device.
Three precision dual range current clamps (20 A/200 A) for
