Specifications
Advanced silicon technology delivers 0.05% accuracy over ranges to 20,000 psi, min/max, tare and alarm functions, analog output and a pressure switch test function making the DPI 104 suitable for a wide array of pressure sensing applications.
| Accuracy | 0.05% FS including non-linearity, hysteresis,repeatability and temperature effects from 14°F to 122°F (-10°C to 50°C) |
|---|---|
| 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 |
| 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 |
