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

DPI 104 - Digital Test Gauge Pressure Ranges

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
