AC/DC current probes

2 March 2011 Test & Measurement

GMC-I PROSyS has extended its CP3 range of AC/DC, non-invasive current measurement probes. Offering measurement sensitivity into the milliamp range, and with resolution of 1 mA, the CP3 range provides engineers with probes that are designed for detecting and measuring leakage currents in automotive systems, or verifying correct operation in process control signal loops.

The probes employ the clamp-on format: with one-handed operation, the user opens the jaws of the probe, closes it around the conductor carrying the current to be measured, and immediately gets a calibrated voltage output that directly represents the current to be measured. The CP3 probes use compensated Hall Effect technology to detect the magnetic field generated by the measured current, a technique that allows both AC and DC currents to be monitored by the same probe. When measuring AC, frequency response extends to 100 kHz.

The magnetic circuit employed in the CP3 range offers very high rejection of external magnetic fields, and very low errors due to off-centre positioning of the conductor within the measurement aperture. For the user, this means that the probe can easily be positioned in awkward, hard-to reach spaces and will return an accurate reading free from concerns about precisely orienting the unit or of the influence of nearby sources of interference such as large electric motors. Similarly, they offer high immunity to voltage transients (dV/dt rejection), further adding to their usability in electrically noisy environments.

Features of the probes include automatic power-off to preserve battery life (which can be disabled for long measurement runs) and auto-zeroing. The probes can be ordered with measurement jaw apertures of 25 or 32 mm, and come in single- or multirange versions with full-scale measurement capability extending up to 300 A.
