DatasheetDPI 104 from Druck is a microprocessor-controlled digital pressure gauge that offers an excellent combination of accuracy, versatility, and durability. Designed for test and calibration applications in industrial environments, it is ideal both as a stand-alone device or as part of a complete calibration solution with Druck’s hand pumps.
Main Features:
- 0.05% full-scale (FS) accuracy, including linearity, hysteresis, repeatability, and temperature effects
- Pressure ranges up to 1,400 bar (20,000 psi)
- 11 selectable pressure units (bar, psi, mbar, kPa, MPa, inHg, mmHg, etc.)
- Large, high-contrast LCD display with 5-digit resolution
- Additional bar graph for quick pressure overview
- Temperature-compensated accuracy from -10°C to +50°C
- Configurable 0–5 V analog output
- Switch test function with precise detection of open/close points
- Min/max value display, tare function, and alarms
- RS232 interface and IDOS compatibility
- Free SiCalPro software for remote monitoring and control
- Stainless steel or Inconel pressure cavity for aggressive media compatibility
Typical Applications:
- Pressure system testing and calibration
- Process monitoring
- Mobile or fixed industrial applications
- Use in aggressive media environments
