The iQunet Current Clamp Module is an AD-converter interchangeable plug-in module for the iQunet Wireless Sensor Bridge. The module accepts an analog signal from the iQunet Current Clamp (clamp and/or cable not included) and converts the analog IEPE compatible current clamp signal to digital, ready for wireless transfer via the Wireless Sensor Bridge.

Description

Current Clamp Module (IEPE Compatible)

The iQunet Current Clamp Module is an AD-converter interchangeable plug-in module for the iQunet Wireless Sensor Bridge. The module accepts an analog signal from the iQunet Current Clamp (clamp and/or cable not included) and converts the analog IEPE compatible current clamp signal to digital, ready for wireless transfer via the Wireless Sensor Bridge. The module can thus be seen as a small measuring unit that makes the analog data compatible with the iQunet system and that makes it possible to set the analog sensor parameters such as sampling rate, number of samples, automatic measurement interval, etc. remotely.

The plug-in module transfers the digital Current Clamp signal to the Repeater module build into the Wireless Sensor Bridge. Sensor data is visualized in the iQunet Sensor Dashboard on the iQunet Data Server, offering time series in current (A) and charge (A.s), spectrum graphs in (A), and (A.s) including waterfall plots, RMS trend values, etc.

Used for: the analog to digital conversion of the time waveform and data acquisition of the current clamp signal
