Benefits
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 (1,400 bar); burst pressure 29,000 psi (2,000 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.
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
Pressure ranges
The DPI 104 can accommodate pressure ranges up to 20,000 psi (1,400 bar) with 0.05% full scale (FS) accuracy.
