Metrix HX0072 Flexible current transformer Ampflex / Probix Ø 24 cm, 5...3500 A, 10 Hz…200 kHz content_copy

The article HX0072 from Metrix is a flexible current transformer of the AmpFlex® series, specifically developed for use with SCOPIX oscilloscopes featuring a Probix connection. It is designed for measuring alternating currents in the range of 5 A to 3000 A RMS with a bandwidth of 10 Hz to 200 kHz. The flexible design with an opening diameter of 240 mm allows measurement on cables or conductors without physical intervention in the electrical installation, making it particularly suitable for applications in power distribution or on large machinery.

Applications
The HX0072 is designed for measuring AC currents in industrial and power engineering installations. It is suitable, for example, for monitoring power consumption in distribution shafts, during machine commissioning, or for troubleshooting in electrical systems. The high measurement range of 5 A to 3000 A RMS allows application across various power levels, from smaller drives to large-scale installations. The bandwidth of 200 kHz also makes it suitable for applications involving rapid signal changes, such as those occurring in power electronics.

Functions and Features in Detail
The device operates on a plug-and-play principle: once connected to a compatible SCOPIX oscilloscope, it is automatically recognized. The oscilloscope identifies the probe and sets its technical characteristics, including measurement ranges and bandwidth. This enables quick and error-free setup without manual adjustments. Power supply and calibration are provided directly via the oscilloscope, eliminating the need for external power sources or calibration equipment. The integrated active safety ensures that relevant information and safety warnings for the used accessory are displayed, enhancing measurement safety.

Technology Explained Simply
The HX0072 uses AmpFlex® technology, enabling a flexible, ring-shaped measuring clamp. Measurement is performed non-contact via the magnetic flux generated by the current to be measured. The internal electronics of the transformer are designed to be powered through the connection cable from the oscilloscope, eliminating the need for additional batteries or external power supplies. The measured values are transmitted directly to the oscilloscope via the Probix connection, enabling direct display and processing of data. The bandwidth of 200 kHz allows capture of signals at high frequencies, which is important for analyzing PWM controls or other fast electrical processes.

Compatibility and Accessories
The HX0072 is specifically developed for SCOPIX oscilloscopes with Probix connection. It is part of the PROBIX system, which provides a standardized interface for measurement probes and accessories. Compatible devices include, for example, the oscilloscope series OX 9000. The use of BNC connectors or standard cables is also possible if connected using the included safety adapters.

Installation and Mounting
Installation is performed by simply placing the flexible clamp around the cable or conductor to be measured. The probe is connected to the oscilloscope, where automatic recognition and configuration are handled by the device. No additional tools or settings are required. The flexible design allows easy adaptation to different cable diameters, with a maximum opening diameter of 240 mm providing broad application possibilities.

Operational Advantages
The HX0072 offers fast and safe measurement without physical intervention in the electrical installation. Automatic recognition and configuration by the oscilloscope reduce the risk of errors during measurement. Direct power supply via the oscilloscope reduces the number of required components and simplifies handling. The integrated active safety increases measurement safety by displaying relevant information and warning messages. The high bandwidth of 200 kHz enables measurement of fast electrical processes, making it particularly suitable for modern applications in power electronics.
