Unit UT-CS09D Flexible Clamp Sensor

The Unit UT-CS09D Flexible Clamp Sensor is a professional-grade tool utilizing Rogowski coil technology to measure AC current in challenging environments. Its flexible design allows it to wrap around large conductors or fit into tight spaces where rigid clamp meters are ineffective. This sensor provides high precision and reliability, making it an essential component for electrical diagnostics and industrial maintenance tasks.

Advantages

The primary advantage of this flexible clamp sensor is its ability to reach conductors in confined areas, significantly improving accessibility for technicians. With a measurement range reaching up to 3000A, it is capable of handling high-current industrial installations with ease. The device is built for durability, featuring a robust design that withstands drops from up to one meter, and it adheres to strict safety standards, ensuring reliable performance in demanding electrical environments.

Suitable for

• Measuring AC current in crowded electrical panels
• Monitoring large-diameter cables and busbars
• Industrial electrical maintenance and troubleshooting
• High-current power system diagnostics

This sensor may not be suitable for measuring DC current, as it is specifically designed for AC applications using Rogowski coil technology. It is also not intended for use in environments exceeding its specified temperature or humidity ranges, nor should it be used on circuits exceeding the CAT IV 600V safety rating.

Key specifications

• Measurement range: 30A, 300A, 3000A AC
• Frequency response: 45Hz to 500Hz
• Clamp length: 45.7 cm
• Safety rating: CAT IV 600V
• Drop resistance: 1 meter
• Power supply: 3 x 1.5V R03 batteries

To use the sensor, connect it to a compatible measuring instrument using the provided BNC adapter. Ensure the batteries are correctly installed in the sensor housing. Wrap the flexible coil around the conductor you wish to measure, ensuring the conductor is centered within the loop for maximum accuracy. Once secured, select the appropriate current range on your connected meter and observe the readings on the display.

What to consider before purchase

• Verify compatibility with your existing multimeter or power analyzer
• Ensure the 45.7 cm loop length is sufficient for the diameter of the conductors you intend to measure
• Confirm that your application involves AC current only

Usage recommendations: Always inspect the flexible coil for signs of wear or damage before each use to ensure measurement accuracy and operator safety. Store the device in a dry, temperature-controlled environment when not in use to maintain the integrity of the sensor components.
