Druck DPI104 Pressure Gauge

The Druck DPI104 is a microprocessor-controlled digital pressure gauge that combines precision and functionality in a compact, robust and simple-to-use package. The DPI104 matches advanced silicon sensor technology with several convenient design features, resulting in an accurate, versatile yet affordable pressure gauge.


Druck DPI104 Key Features:

  • 0.05% full scale (FS) accuracy
  • Pressure ranges to 20,000 psi (1400 bar)
  • Eleven selectable pressure units
  • Large, easy-to-read display with five-digit resolution
  • % pressure indication and additional bar graph for quick visual reference
  • Temperature compensated accuracy from 14°F to 122°F (-10°C to 50°C)
  • 0 to 5V analog output
  • Pressure switch test
  • Minimum/maximum, tare and alarm functions
  • IDOS compatible and RS232 serial interface
  • Free of charge monitoring and control software
  • Stainless steel or Inconel pressure cavity for aggressive media


Druck DPI104 Specification:

Accuracy and Resolution:

  • Accuracy: 0.05% FS including non-linearity, hysteresis, repeatability and temperature effects from 14°F to 122°F (-10°C to 50°C)
  • Resolution: Maximum five digits


DPI104 Pressure Ranges Chart:

RangeResolutionMaximum working pressure
0-300-2G* or A0.0010.01322.2
0-1000-7G* or A0.011111.77.7
0-3000-20G* or A0.01131922
0-10000-70G* or A0.011111777

*All gauge models will respond to negative pressures **0.15% FS for 10 psi (700 mbar) range

  • Burst pressure: Burst pressure is 2x working pressure (exception, 20,000 psi (1400 bar); burst pressure 29,000 psi (2000 bar)
  • Selectable pressure units: kPa, MPa, kg/cm2, psi, mbar, bar, in Hg, in H2O, m H2O, mm H2O and mm Hg



  • Pressure reading: 5 digits with 0.5 in (12.7 mm) character height
  • Full scale indicator: 2.5 digits with 0.25 in (6.35 mm) character height
  • Pressure bar graph: In addition to the numeric pressure indication, the DPI104 LCD display contains a circular twenty segment bar graph to provide the user with a quick visual estimation of pressure from 0 to 100% full scale output. The bar graph increments represent 5% of the user-selectable range
  • Display Update: 2 x per second


Values and Output:

  • Minimum/maximum values: The minimum and maximum pressure values can be displayed on the DPI 104. This function can be enabled/ disabled, and reset by the user
  • Switch test: The DPI 104 features a switch test function that will capture and display the open and closed values from an external pressure switch. Maximum switch impedance 200 Ω
  • Voltage output: The DPI 104 can be programmed to provide a 0 to 5 V output signal that can be configured as directly proportional to the pressure shown in the display or set to a fixed value. The voltage output mode provides 0.1% FS accuracy from 50 mV to 5 V
  • Alarm output: The alarm output consists of an open drain field effect transistor (maximum current 250 mA, maximum voltage 24 VDC)


Hardware and Security:

  • Adjustable mounting positions: For added convenience, the DPI 104 housing will rotate 320° around the pressure fitting and the faceplate can be rotated in any orientation for optimum visibility
  • Pressure port:
    • 1/4 NPT or BSP male for units to 10,000 psi (700 bar)
    • 9/16 x 18 UNF male cone connection 15,000 psi (1000 bar) and 20,000 psi (1400 bar) units
  • Enclosure
    • Case material: ABS/PC plastic sealed to Type 4/ IP65
    • Wetted parts: All stainless steel (316) or Inconel welded pressure cavity for compatibility with aggressive media
  • Menu lock: To guard against unauthorised menu access, the DPI 104 features a menu and tare lock function


Interface and Capability:

  • RS232 interface: Serial communications are provided to allow transfer of data to a PC with the optional serial lead (IA4090-2-V0). Using this link, all menu commands and display data are available via an ASCII command set or the optional SiCal Pro Software
  • Network capability: Up to 99 DPI104 instruments can be connected together in a daisy chain-configured network
  • Universal Pressure Module (UPM) capability: UPM modules can be connected to the DPI 104 to enhance the accuracy and extend the pressure range
  • Battery: The DPI104 is supplied with a 9V alkaline battery, type MN1604. Battery life is approximately six months when used daily for one hour per day. For increased performance a 9V lithium battery (not supplied by Druck) is suggested


Druck DPI104 Applications:

  • Process monitoring and control
  • Test and calibration
