DatasheetThe Druck DPI 802 is a robust, portable pressure loop calibrator specifically designed for demanding industrial maintenance and calibration tasks. Its capability to simultaneously measure pressure and electrical signals (mA) makes it the ideal instrument for quick, precise, and efficient maintenance of transmitters and process loops.
Key Features of DPI 802:
- Pressure ranges from 25 mbar to 700 bar (10 inH₂O to 10,000 psi), including vacuum measurements
- Configurable with single or dual sensors for extended range or differential pressure measurements (P1-P2)
- Integrated 24 V loop power supply for powering transmitters and control loops
- Automatic switch test function for quick and precise detection of switching points (open/closed)
- Selectable internal HART® resistor (250 Ω) for seamless digital communication with HART-enabled devices
- Large, easy-to-read backlit display with intuitive menu-driven interface
- Robust, weatherproof design ideal for harsh operating conditions
- Compact form factor with ergonomic one-handed operation and impact-resistant protective cover
- Plug-and-play compatibility with universal pressure modules (IUPM/IUPMP) to expand measurement ranges and accuracy
- Programmable leak test for automatic detection of pressure drops and leak rates
- Advanced features such as hold, min/max/average readings, alarms, and tare for efficient troubleshooting
Typical Applications:
- Calibration and maintenance of pressure measuring instruments and transmitters
- Setup and diagnostics of process control loops
- Testing and calibration of switches, safety, and shutdown systems
- Pressure and current measurements in industrial environments
