Description
The Fluke 771 is a Milliamp Clamp Meter designed for efficient and accurate testing and troubleshooting of 4-20 mA current loops in industrial process control systems.
Key Features:
- Measures 4 to 20 mA signals without breaking the loop
- Best in class 0.2% accuracy
- Delivers 0.01 mA resolution and sensitivity
- Measures mA signals for PLC and control system analog I/O
- Detachable clamp for measurements in tight locations
- Non-Invasive Measurement: The 771 utilizes a clamp-on design, allowing you to measure the current flowing through a conductor without breaking the loop. This eliminates the need to disconnect wires, minimizing downtime and reducing the risk of errors.
- High Accuracy: Provides accurate and reliable measurements of 4-20 mA signals.
- Versatility: In addition to mA loop measurements, the 771 can also measure AC/DC voltage, resistance, and frequency.
- User-Friendly Interface: Features an intuitive interface with a clear display for easy operation and data interpretation.
- Rugged and Durable: Designed to withstand harsh industrial environments and provide reliable performance in demanding conditions.
Applications:
- Process Instrumentation: Troubleshooting and calibration of 4-20 mA transmitters, sensors, and control loops in industrial plants.
- Predictive Maintenance: Identifying potential problems within 4-20 mA loops before they lead to equipment failures or production disruptions.
- Electrical Troubleshooting: Diagnosing electrical issues in industrial equipment and systems.
- Process Optimization: Ensuring accurate and reliable signal transmission within process control systems.
In Summary:
The Fluke 771 is a valuable tool for technicians and engineers working with 4-20 mA loops. Its non-invasive measurement capabilities, speed, accuracy, and rugged design make it an efficient and reliable solution for troubleshooting, maintaining, and optimizing industrial processes.
