Intrinsically Safe Digital Test Pressure Gauge, 0.05% Full Scale Accuracy
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 stand-alone process indicator or in a kit with the widely proven Druck hand pumps, the DPI 104 provides a reliable and economic solution for a wide range of pressure sensing applications.
Applications
- Process monitoring and control
- Test and calibration
Features and Benefits
- 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 - 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 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). - 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.
