Druck DPI 842 Loop Calibrator with Frequency Generator

The Druck DPI 842 is a professional loop calibrator from the GE Druck DPI 800 Series, designed for demanding industrial environments. This hand-held instrument combines advanced functionality with rugged construction, making it an essential tool for calibration and maintenance technicians. With its ability to measure and source mA, perform switch tests, and provide 24V loop power, the DPI 842 simplifies loop calibration tasks. Additionally, its integrated frequency generator with three output waveforms (sine, square, and triangular) expands its utility to frequency-based applications.

Key Features & Highlights

• mA Measure, Source, and Switch Test: Accurately measure and source current, and perform switch tests to verify loop integrity.
• 24V Loop Power: Power transmitters and other loop-powered devices directly from the calibrator.
• Frequency Generator: Generate sine, square, and triangular waveforms from 0.01 Hz to 50 kHz, with amplitude adjustable from 0.1V to 24V.
• CPM, CPH, and Totalizing Counter: Measure frequency in cycles per minute (CPM), cycles per hour (CPH), or as a totalizing counter.
• HART Loop Resistor: Built-in resistor enables HART communication without external components.
• IDOS Pressure Module Compatibility: Connect to IDOS pressure modules to measure pressure from 10 inH2O to 10,000 PSI, expanding functionality.
• Large Backlit Display and Menu-Driven Interface: Easy-to-read screen and intuitive navigation for efficient operation.
• Rugged and Impact Resistant: Elastomer-protected housing withstands harsh field conditions.
• Complete Kit: Includes calibration certificate, batteries, and electrical test leads.

Applications

The Druck DPI 842 is ideal for calibrating and troubleshooting process instrumentation in industries such as oil and gas, chemical, pharmaceutical, power generation, and water treatment. It is well-suited for verifying 4-20 mA loops, testing frequency-based sensors, and performing routine maintenance on control systems. Its portability and robust design make it a reliable companion for field service engineers and calibration technicians.
