Clamp-on Current Monitor

Why choose a Pearson Electronics Clamp-on
Current Monitor?

· Patented technology that has been manufactured since 1955 by the inventor   Paul Pearson.

· Accurate measurement of complex current waveshapes from microamperes   to kiloamperes.

· Wideband frequency response.

· Shielded and ohmically isolated from the circuit for operation in noisy   environments.

· Available in many sizes and configurations.

Pearson Clamp-on Current Monitor
Clamp-On Current Monitor
The Pearson Clamp-on
Current Monitor facilitates measurement of current
without opening the circuit. There are two different designs. One consists of two parts that may be separated to allow clamping around the conductor to be monitored. The other with a hinged type opening.





The Pearson Clamp-on Current Monitor is designed to maintain its wide bandwidth and accuracy. Clamp-on's with apertures from 1/2 inch to 18 inches have been manufactured with certain models in stock and available for immediate delivery

Accuracy ±1% or better, initial pulse response for all models, with a high impedance load such as 1 megohm in parallel with 20 pF. A 50 ohm termination will reduce the output to half.
