LiebeWH ETCR035AD AC DC Clamp Current Sensor BNC Phase Electric Energy Power Tester Anti Interference Current Sensor

Description

Product Overview

The LiebeWH ETCR035AD is a professional-grade AC/DC clamp current sensor designed for demanding electrical testing environments. Built around a split‑core design, the sensor can be clamped around a conductor without breaking the circuit, allowing safe and rapid measurement of both alternating and direct currents. The heart of the device is a Hall‑effect transducer that converts magnetic flux generated by the current into a proportional voltage signal, ensuring linear response across a wide range of amplitudes. The sensor housing incorporates a high‑grade permalloy core surrounded by magnetic shielding made from a specialized alloy, which together suppress external electromagnetic noise and provide exceptional anti‑interference capability. With a compact form factor measuring 8.66 x 4.33 x 2.76 inches and weighing only 6.35 ounces, the unit is portable enough for field technicians yet robust enough for industrial‑scale deployments. The BNC output connector enables seamless integration with a variety of measurement instruments, including oscilloscopes, data loggers, and power quality analyzers. Designed to meet stringent industrial standards, the ETCR035AD delivers repeatable accuracy, fast response time, and reliable performance in harsh environments, making it a trusted tool for power engineers, maintenance crews, and research laboratories.

Usage

This clamp sensor excels in a broad spectrum of applications where precise current monitoring is essential. In power generation facilities, it can be used to verify transformer loading, monitor generator output, and assess line losses without interrupting service. Electrical contractors often employ the device during commissioning and troubleshooting of motor drives, variable frequency drives, and inverter systems, where quick verification of AC and DC currents helps prevent equipment damage. In renewable energy installations, such as solar farms and wind turbines, the sensor provides real‑time data for performance optimization and fault detection. Laboratory researchers benefit from the non‑intrusive measurement capability when conducting experiments on new power electronics prototypes, allowing them to capture transient current waveforms with high fidelity. The BNC output makes it straightforward to connect the sensor to digital multimeters, oscilloscopes, or dedicated current‑analysis software, enabling automated data logging and long‑term trend analysis. Because the sensor does not require any disconnection of the test circuit, it enhances safety for operators and reduces downtime for critical systems.

FAQ

How does Hall induction technology work in this sensor?

Hall induction relies on the Hall effect, where a magnetic field generated by the current flowing through a conductor creates a voltage across a semiconductor element placed perpendicular to the field. This voltage is directly proportional to the magnitude of the current, allowing the sensor to convert magnetic flux into an electrical signal that can be read by external instruments. Because the Hall element is isolated from the conductor, the sensor can measure both AC and DC currents without needing to break the circuit.

Can the sensor measure both AC and DC simultaneously?

Yes, the split‑core design combined with the Hall‑effect transducer enables simultaneous detection of AC and DC components in a single measurement. The sensor’s internal processing separates the two waveforms, providing accurate readings for each type of current, which is especially useful in mixed‑signal power systems such as motor drives and renewable energy converters.

What types of equipment can I connect to the BNC output?

The BNC connector is a standard 50 Ω interface compatible with most laboratory and field instruments. You can connect the sensor to digital oscilloscopes for waveform analysis, data loggers for long‑term monitoring, power quality analyzers for harmonic and distortion studies, as well as handheld multimeters that support external voltage inputs. The gold‑plated contacts ensure low‑noise signal transmission.

Is the sensor suitable for use in harsh industrial environments?

Absolutely. The sensor’s housing is made from flame‑retardant polymer that meets UL94 V‑0 standards, and the internal components are rated to operate from –20 °C to +60 °C. The magnetic shielding protects the measurement from nearby high‑current equipment, while the robust mechanical construction resists vibration and impact, making it ideal for factories, substations, and outdoor field work.

What warranty and support does LiebeWH provide?

LiebeWH offers a one‑year limited warranty covering defects in materials and workmanship. In addition, the company provides technical support through phone, email, and an online knowledge base. Calibration services are available at authorized service centers, and firmware updates are released periodically to enhance performance and compatibility.
