AC/DC Current Sensor

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 or CM7291 to capture instantaneous waveforms that can be output to a Hioki memory recorder or logger for further analysis. Mix and match with other sensors in the series for a cost-effective solution covering a broad measurement range. CAT IV 600 V Key Features • Ideal for observing instantaneous waveforms in laboratories and other temperature-controlled environments • Ideal for site inspections by using detachable Display Unit • Four output formats to output data to loggers or other devices (via Display Unit): WAVE, RMS, PEAK, Hz

Model No. (Order Code)

CT7631	100 A AC/DC, φ33 mm (1.30 in)

Note: CT7600 series cannot be used alone. Use with the Display Unit CM7290, CM7291 to connect with Data Loggers and Memory HiCorders. When used in combination with CM7290 or CM7291, the frequency band of current display and waveform output becomes narrow.

Connect to Recorders, Data loggers, and Oscilloscopes

Must be paired with the Display Unit CM7290 or CM7291 to operate as a standalone unit. Add an output cord to deliver signals to a data logger or Memory HiCorder for the following types of output: • A DC or AC (up to 5 kHz/10 kHz) current waveform as-is (using WAVE mode for waveform output) • An analog signal generated by converting the input waveform to a series of RMS values (using RMS mode for RMS output) • An analog signal generated by detecting the current waveform’s peak value (using PEAK mode for peak output • An analog waveform generated by detecting the frequency of the current waveform (using FREQ mode for frequency output)

Broad temperature range

A wide operating temperature range of -25°C to 65°C (-13°F to 149°F)lets you use the sensor even in sub-freezing temperatures and on hot summer days.

Transfer data wirelessly using Bluetooth(R) to GENNECT Cross mobile app

Pair with the CM7291 Display Unit to send measurement data to a smartphone or tablet using Bluetooth® wireless technology. Use the GENNECT Cross dedicated app to display and review measured values and waveforms in real time.
