Description
The Fluke 787B ProcessMeter is a versatile and powerful tool that combines the functionality of a high-performance digital multimeter (DMM) with a 4-20 mA loop calibrator in a single, compact unit.
Key Features:
- Versatile Measurement Capabilities:
- DMM Functions: Measures voltage (AC/DC), current (AC/DC), resistance, frequency, capacitance, and more, providing comprehensive electrical measurement capabilities.
- mA Loop Calibration: Sources and measures 4-20 mA signals, allowing for accurate calibration and troubleshooting of process loops.
- Enhanced Functionality:
- Simultaneous mA and % of Scale Readout: Displays both mA and percent of scale readings simultaneously, simplifying loop calibration and troubleshooting.
- Loop Power Supply: Provides loop power to transmitters, eliminating the need for a separate power supply.
- Rugged and Durable: Designed to withstand harsh industrial environments and provide reliable performance in demanding conditions.
- User-Friendly Interface: Intuitive controls and a clear display make it easy to operate and interpret measurements.
Applications:
- Process Instrumentation: Calibration and troubleshooting of process transmitters, sensors, and control loops in industrial plants.
- Electrical Troubleshooting: Diagnosing electrical problems in industrial equipment and systems.
- Maintenance and Repair: Identifying and resolving electrical and instrumentation issues during equipment maintenance.
- Predictive Maintenance: Monitoring the health of process equipment and identifying potential problems before they lead to costly downtime.
The Fluke 787B is a valuable asset for industrial technicians and engineers. Its combination of DMM functionality, advanced loop calibration capabilities, and rugged design makes it a powerful tool for improving process efficiency, reducing downtime, and ensuring the reliable operation of industrial processes.
