About Fluke Loop Calibrators & Process Meters
Fluke loop calibrators are precision instruments designed to source, simulate, and measure milliamp (mA) signals in control systems, particularly within 4-20 mA current loops. These devices are essential for calibrating and maintaining process instrumentation in various industrial settings.
Functions and Measurements
- Current Sourcing and Simulation: Fluke loop calibrators can generate precise mA signals to test and calibrate devices like transmitters and controllers.
- Current Measurement: These calibrators accurately measure current signals within a loop, ensuring that instruments operate correctly.
- Voltage Measurement: Some models can measure DC voltage up to 28 V, allowing users to verify loop power supplies. The Fluke 707, for instance, measures V DC to 28 V.
- Loop Power Supply: Certain calibrators provide a 24 V loop supply, enabling them to power transmitters during testing without the need for an external power source.
- HART Modem: Models such as the Fluke 709 and 710 can communicate a range of HART commands improving the ease, efficiency and effectiveness of testing.
Applications
- Process Instrumentation Calibration: Ensuring that instruments like transmitters, controllers, and sensors provide accurate readings by calibrating them with precise mA signals.
- Loop Integrity Testing: Verifying the proper functioning of current loops in control systems to detect issues such as wiring faults or device malfunctions.
- Maintenance and Troubleshooting: Assisting technicians in diagnosing and resolving problems within process control loops to maintain system reliability.
