The DPI 104 is a microprocessor-controlled digital pressure gauge that combines precision and functionality in a compact, robust and simple-to-use package. The DPI 104 matches advanced silicon sensor technology with several convenient design features resulting in an accurate, versatile yet affordable digital test gauge. Supplied as a standalone process indicator or in a kit with the widely proven hand pumps, the DPI 104 digital pressure gauge provides a reliable and economic solution for a wide range of pressure sensing applications.
The DPI 104 can be used as a stand-alone process indicator or as a pressure reference for use with our widely popular hand pumps.
| 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, inHg, inH2O, mH2O, mmH2O and mmHg |
| 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 DPI 104 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 | Two times per second |
| 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 O. |
| 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) |
| 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. |
| Menu Lock | To guard against unauthorized menu access, the DPI 104 features a menu and tare lock function |
| 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 DPI 104 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 DPI 104 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 GE) is suggested. |
| 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. |
| European Compliance | CE marked |
| SiCalPro Software | This software package allows the user to control the DPI 104 remotely through a virtual instrument panel on the computer screen. The calibration data can be logged, viewed and printed in graphical format or as a calibration certificate. |
| System Requirements | Minimum Intel Pentium with Windows® 95 or higher |
| General | |
| Storage Temperature | -4°F to 158°F (-20°C to 70°C) |
| Dimensions | Diameter: 3.74 in (95 mm) excluding pressure fittings Depth: 2.17 in (55 mm) |
