*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
Display:
- 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
