Pearson Electronics has recently designed several new current transformers with a thickness that is about 1/2 of the size of the in stock current transformers designed by Pearson.  The thin model 8105-03 is shown below next to our in-stock model 2878. These new ultra thin current transformers allow a more compact installation resulting in lower circuit inductance. Apertures range in size from 0.25 inches to 2.0 inches and the models have the same footprint as our in stock current transformers, except for thickness.  Designs include BNC and SMA connectors depending upon the model.

These ultra thin designs incorporate Pearson’s wide-band frequency response and 1% accuracy, or better, across the mid-band.  The model 8105-03  has a 0.25 inch aperture, a 0.1 V/A transfer impedance with a 3 dB bandwidth from 50Hz to 40MHz. The maximum rms current rating is 6 Amperes.  Peak currents up to 300 Amperes and rise times as short as 5 nanoseconds can be viewed faithfully.  Contact a Pearson Electronics for a complete listing of the ultra thin current transformers.

New line of Wide-Band Clamp-on Current Monitors features a 4 inch or 6 inch aperture in a demountable configuration for easy use on large conductors.  The Pearson’s wide-band current monitors frequency response and 1% accuracy is featured in all of the models.

The model 7655 has a sensitivity of 0.1 V/A, a 3dB bandwidth from 10 Hz to 4 MHz, and a 175 Ampere rms current rating. Accuracy of 1%, or better, is obtainable across the mid-band.  Pulse currents up to 5,000 Amperes and rise times down to 100 nanoseconds can be viewed faithfully.  Other new large aperture clamp-on models feature a range of transfer impedance from 0.01 V/A to 1.0 V/A.   Electrical specifications range from rise times as short as 25 nanoseconds, or droop as low as 0.001% per microsecond.  All of the new large aperture clamp-ons are featured in our Clamp-on Current Monitor section along with existing custom and stock designs.

Data Sheet

Several new ultra-thin  wide band current transformers have been released by Pearson Electronics with a thickness that is around 1/2 the size of standard / in stock current transformers designed by Pearson.  These new ultra thin broadband current transformers allow a more compact installation resulting in lower circuit inductance. Apertures range in size from 0.25 inches to 2.0 inches and the models have the same footprint as our in stock current monitors, except for thickness.  Designs include BNC and SMA connectors depending upon the model.

These designs incorporate Pearson’s wide-band frequency response and 1% accuracy, or better, across the mid-band. The model 8500 has a 2.0 inch aperture, a 0.1 V/A transfer impedance with a 3 dB bandwidth from 10Hz to 20MHz. The maximum rms current rating is 75 Amperes.  Peak currents up to 5,000 Amperes and rise times as short as 20 nanoseconds can be viewed faithfully.  Contact a Pearson Electronics for a complete listing of the ultra thin current transformers.

Pearson Electronics introduces a new wide band current monitor that allows you to easily measure current within a coaxial cable system.  The current monitor can be inserted within a coaxial cable run by means of two BNC connectors. The Model 6027 has a 3dB bandwidth from 300 Hz to 200 MHz and an rms current rating of 2.5 Amperes.   Accuracy of 1%, or better, is obtainable across the mid-band.  Pulse currents up to 10 Amperes peak and rise times as short as 2 nanoseconds can be viewed faithfully. Other coaxial designs include ones with HN and triax connectors as well as ones that are double shielded.

A new line of Wide-Band Clamp-on Current Monitors from Pearson Electronics feature a ½ inch or 1 inch aperture and are hinged for easy operation. The new design incorporates Pearson’s wide band frequency response in a demountable configuration for use on fixed conductors.

The model 411C, typical of the group, has a sensitivity of 0.1 V/A, a 3dB bandwidth from 15 Hz to 20 MHz, and a 50 Ampere rms current rating. Accuracy of 1%, or less, is obtainable across the mid-band.  Pulse currents up to 5,000 Amperes and rise times down to 20 nanoseconds can be viewed faithfully.  Other new hinged clamp-on designs feature a range of transfer impedance from 0.01 V/A to 1.0 V/A. Electrical specifications range from rise times as short as 2.0 nanoseconds, or droop as low as 0.003% per microsecond.  All of the new hinged clamp-ons are featured in our Clamp-on Current Monitor section along with existing custom and stock designs.

Pearson Electronics has recently developed an updated Current Probe EMI Specification list along with transfer impedance curves for certain Clamp-on Current Probes. The EMI Specification List includes over twenty-five different standards and the recommended Pearson Clamp-on Current Probe to make those EMI measurements. It’s the Pearson’s wide band frequency response and high transfer impedance which allows for accurate EMI measurements.

The model 3525, typical of the group, has 6 decade flat transfer impedance, 10Hz to 10MHz, which exceeds the performance of any other large window passive EMI current probe presently available.  Other Pearson Clamp-on Current Probes can measure current as low as 10 micro amps (20 dBuA) and frequencies as high as 200 MHz.  All of our Clamp-on Current Probes can be found in our Clamp-on Current Probe  section; transfer impedance curves and the Current Probe EMI Specification list can be found in our EMI Test Application section.
