Precise Low Resistance Measurement

This Kelvin Double Bridge is engineered for determining extremely low resistances in industrial settings, ranging from 1 microohm to 11 ohms. Its analog display and use of a galvanometer (not included) facilitate sensitive and accurate measurement, ideal for diagnosing and maintaining cable, transformer, wire, and electrical contact resistance.

Rugged Industrial Design

Constructed with a heavy-duty, powder-coated Bakelite base and robust brass terminals, the bridge ensures both durability and minimal contact resistance. Its high-grade materials are selected for longevity and reliability, making it suitable for busy industrial laboratories and harsh fields.

Superior Accuracy and Calibration

The instrument boasts an accuracy of 0.05% of reading thanks to enclosed wire wound standard resistors and precision ratio coils. Factory calibration is traceable to national standards, ensuring trustworthy measurements for critical industrial testing purposes.

FAQs of Industrial Kelvin Double Bridge:

Q: How is the Industrial Kelvin Double Bridge used for measuring low resistance in cables and transformers?

A: The bridge is connected to both ends of the test objectsuch as a cable or transformer windingusing the supplied low-resistance leads. By adjusting the ratio coils and balancing the galvanometer, users can obtain precise resistance values ranging from 1 microohm to 11 ohms.

Q: What are the benefits of using this Kelvin Double Bridge for industrial applications?

A: Benefits include high measurement accuracy (0.05% of reading), robust construction for industrial environments, no need for an external power supply, and traceable calibration ensuring reliable and repeatable results for key maintenance and quality control tasks.

Q: When should the bridge be recalibrated to maintain measurement accuracy?

A: Although factory-calibrated and traceable to national standards, recalibration intervals depend on the usage frequency and criticality of measurements, but an annual calibration is generally recommended for high-precision industrial applications.

Q: Where can this instrument be applied most effectively?

A: It is best suited for testing extremely low resistances in cables, transformer windings, electrical wires, and contact points, especially in manufacturing plants, electrical utilities, and quality control laboratories.

Q: What is the process for obtaining reliable measurements with the Kelvin Double Bridge?

A: Ensure secure connections to the object and the brass terminals using the provided leads. Adjust the bridges ratio arms and use a sensitive galvanometer to achieve a balanced null point, then read the resistance from the analog display according to the bridge settings.

Q: How does the manual operation provide advantages over powered instruments?

A: Manual operation eliminates the need for electrical power sources, promoting portability, long-term reliability, and safety when performing field or lab measurements, particularly in challenging or remote environments.
