DC/AC Precision Current Transducers
DaniSense DS Series DCCTs are based on a flux-gate zero flux detector with closed-loop operation to provide a signal output current accurately defined by the number of turns in the compensation winding. They provide higher accuracy for Power Analyzer measurements and improved performance for power amplifiers.
Bergoz IPCT is a High Sensitivity Current sensor operating as a “closed-loop” Direct Current Transducer (DCCT) operating with a flux-gate zero-flux detector. A feed-back loop maintains the magnetic core of the Transducer at zero-flux by generating a “compensation current” through a “compensation winding” on the Transducer magnetic core. The IPCT output is the voltage developed by the feedback current or “compensation current” through a precision “burden” resistor internal to the IPCT.

Rogowski Coil AC Current Probes
PEM AC Current Probes utilize a Rogowski Coil and Matched Analog Integrator to provide accurate non-contact, measurement of AC currents over a very broad frequency range. These flexible “clip-around” Current Probes have very low insertion impedance compared to Current Transformers, (CT), or Hall Current Transducers, are easy to insert in confined spaces and are not damaged by over-current surges. They can be used for measuring ac, pulse or transient current waveforms. Since the PEM Current Probes have no magnetic core they can be used to measure ac current on a conductor with high dc current or in the presence of a high dc magnetic field.

Clip-on/Clamp-on DC/AC Current Probes
GMW DC-AC Clamp-on (CPCO) and Clip (CPC) Current Probes enable electrically isolated monitoring of high electric currents without disconnection of the primary current conductor. The CPCO and CPC current probes have no magnetic core enabling very light weight, no magnetic hysteresis and no damage from unlimited over current. Recovery from overcurrent to linear output operation is within a few microseconds. The current probes are moisture resistant and have operating temperature range of -40C to +100C making them useful as a Current Probe for in-vehicle current monitoring.
