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 secondary current transformer applications.... GFUVE Set of 3 20 A/200 A Current Clamps Expand the capabilities of the GFUVE GF438II and GF312V2 Series Loggers with the dual-range 20 A/200 A.
