Wide-Band High Current Transformer
A new current monitor capable of measuring narrow current pulse of several hundred kA and AC currents up to 2,000 ARMS with a 3 dB bandwidth of 0.1 Hz to 100 kHz is introduced by Ion Physics Corporation, IPC, of Fremont, NH.
This IPC current monitor, also referred as current transformer or current sensor, is a transformer with a one turn primary, internally terminated in a low inductance impedance network to convert the current signal to a voltage signal. This model has the designation CM-01-CS11 and has a sensitivity of 1 mV/A. It senses the magnetic field surrounding the primary current carrying cable or charged particle stream and thus requires no physical contact with the primary conductor, eliminating ground loops and interference noise.
One of the outstanding features of this current monitor is its high saturation limit of 250 As. The 3dB bandwidth ranges from 0.1 Hz to 100 kHz. Its usable risetime is 4 microseconds and the droop 0.1%/ms.
The current monitor is electrostatically shielded and has an O.D. of 30 cm and an I.D. of 15 cm. The CM-01-CS11 monitor sells for $2,500.00. Literature is available upon request.
