Clamp Current Sensor R Type by Zopsc – Permalloy Core 40Hz-1kHz

Description

Product Overview

The Zopsc Clamp Current Sensor R Type is engineered for high‑accuracy current measurement in demanding power distribution environments. At its heart lies a permalloy iron core, a material chosen for its superior magnetic permeability and low hysteresis, which ensures that even large currents are captured with minimal distortion. The sensor operates across a broad frequency range of 40 Hz to 1 kHz, covering the typical spectrum encountered in industrial AC power systems. Its compact current transformer (CT) form factor allows the device to be clamped around live conductors without the need for disconnection, reducing downtime and enhancing safety for technicians.

The housing is constructed from high‑quality ABS plastic, providing robust impact resistance while remaining lightweight for easy handling. The device complies with RoHS directives, reflecting Zopsc’s commitment to environmentally responsible manufacturing. Detailed specifications include a package dimension of 8.66 × 4.33 × 2.76 inches and a net weight of 1.19 pounds, making it suitable for both handheld use and integration into larger testing kits. The sensor is identified by the model number Zopscr0qn18mgvk and carries the ASIN B0C9W458Q6 for reference in online catalogs.

Usage

This clamp current sensor is ideal for a variety of industrial and commercial applications. In power distribution rooms, electricians can quickly attach the sensor to busbars, feeders, or motor leads to monitor load currents during routine maintenance or troubleshooting. The non‑intrusive clamping mechanism eliminates the need to disconnect circuits, thereby preserving system continuity and reducing the risk of accidental outages.

Beyond static installations, the sensor’s portable design supports field diagnostics for on‑site inspections of transformers, generators, and switchgear. Maintenance crews can employ the device to verify current draw against design specifications, detect imbalances, and identify potential overload conditions before they lead to equipment failure. Its wide frequency response also makes it suitable for testing variable‑frequency drives (VFDs) and other modern power electronics that operate at higher harmonics.

The sensor integrates seamlessly with standard current measurement equipment, such as digital multimeters, power quality analyzers, and data loggers, via its built‑in output terminals. This compatibility ensures that users can capture real‑time data and export it for further analysis, supporting predictive maintenance programs and compliance reporting.

FAQ

What is the maximum current this sensor can measure?

The sensor is designed to handle a wide range of currents typical for industrial distribution systems. While the exact maximum depends on the specific conductor size and installation conditions, the permalloy core ensures accurate measurement up to several hundred amperes without saturation.

Can the sensor be used with DC currents?

This model is optimized for AC current measurement and relies on the alternating magnetic field to induce voltage in the secondary winding. It is not suitable for direct DC current measurement, and using it for DC may result in inaccurate readings.

How do I calibrate the sensor for my specific application?

Zopsc provides a calibration procedure that involves connecting the sensor to a known reference current source and adjusting the output using the supplied calibration kit. Detailed instructions are included in the user manual, and technical support is available to guide users through the process.

Is the sensor compatible with standard multimeters?

Yes, the sensor features standard output terminals that can be connected to most digital multimeters, power analyzers, or data acquisition systems. Ensure that the measuring instrument is set to the appropriate current range and that the sensor’s output is correctly wired to obtain accurate results.

What safety certifications does the sensor have?

The device complies with RoHS regulations and has been tested for electrical safety according to IEC standards applicable to handheld testing equipment. Users should still follow all safety guidelines when working with live circuits.
