Hioki CT7631 AC/DC Current Sensors (100A DC-10kHz)

Hioki CT7631 AC/DC Current Sensors (100A DC-10kHz) Hioki clamp on meters are best-in-class measuring devices incorporating Hioki's expertise in current sensing technology. The CT7631 is a 100 A AC/DC Current Sensor that pairs with the detachable Display Unit CM7290 to capture instantaneous waveforms that can be output to a Hioki memory recorder or logger for further analysis. AC/DC Auto-Zero Current Sensor Frequency band: DC to 5 kHz Perform measurement without shifts in the zero-point, even during extended waveform recording or in locations where the temperature varies during measurement. AC/DC Current Sensor Frequency band: DC to 10 kHz Use to observe instantaneous waveforms and make short- term measurement in locations without temperature variations.   AC/DC Auto-Zero Current Sensors Take measurements without shifts in the zero-point, even during extended recording with temperature variations Normal Sensor × New Auto-Zero Sensor × Offset Current × Because measured values acquired using standard sensors exhibit shifts in the zero-point caused by temperature variations, their use in recording data over extended periods of time has required regular zero-adjustment. This issue is caused by the effects of the Hall elements used in the sensor's detection circuitry. Hioki's new auto-zero sensors feature a new, switching-based offset cancellation circuit that was developed to address this issue. This circuit minimizes shifts in the zero-point to enable extended recording without constant zero-adjustment.
