Equipped with a precision low-pressure sensor with pneumatic generation capabilities, the DPI 615 takes the difficulty out of pressure calibration.
The unit’s portable design, integrated carrying/holding handle and simplistic menu system all combine together to make it easy to access the functions you need.
The DPI 615’s pressure range is from 2.5 to 150mbar, with 25 scale units plus one user-defined unit. The calibrator is suitable for generating both pressure and vacuum.
The DPI 615 is the upgraded version of Druck’s DPI 610; this unit includes data storage and an RS232 interface, allowing measurement results to be logged and transferred to PC into an application software package (sold separately).

A highly accurate and easy to use calibrator is only part of the solution for improving overall data quality and working efficiency. The DPI 610 and DPI 615, with data storage and RS232 interface, reduce calibration times and eliminate data recording errors. The DPI 615 also provides error analysis for field reporting of calibration errors and pass/fail status. In addition, procedures downloaded from a PC automatically configure the DPI 615 to pre-defined calibration and test routines
GE’s knowledge of customer needs, combined with innovative design, results in high performance, multi-functional calibrators that are simple to use. The key to simple operation is the Task Menu. Specific operating modes such as P-I, switch test and leak test are configured at the touch of a button by menu selection. Featuring highly reliable pneumatic and hydraulic assemblies and self-test routines, the DPI 610/615 Series can rely upon time and time again for field calibration in the most extreme conditions. The DPI 610 and DPI 615 have been designed for ease of use while meeting a wide range of application needs including calibration, maintenance and commissioning.
The Intrinsically Safe versions, certified to European and North American standards for use in hazardous areas, reduce response times to breakdowns and emergencies by removing the need for ’Hot Permits‘ and gas detection equipment. This gives peace of mind to all those responsible for safety within hazardous areas. The dual parameter display shows the Input and Output values in large clear digits.
A unique built-in handle provides a secure grip for on-site use in addition to a shoulder strap which is also designed to allow the instrument to be suspended for hands-free operation. Any technician can use these calibrators without formal training, such as a novice on an emergency call out, or those familiar with the DPI 601. By selecting basic mode the calibrator is configured to source pressure and measure mA or V, with all non-essential keys disabled.
Dedicated Task Menu
The dedicated task key gives direct access to the task menu. Select the required test, for example P-I for a pressure transmitter, and with a single key press, the calibrator is ready.
Pressure Transmitter Calibration
The P-I task configures the DPI 610/615 Series to simultaneously display the output pressure and the input current. The pressure unit can be chosen to suit the transmitter and a 24 V supply is available for loop-power (not IS version). For process transmitters reading in percentage, use % span to scale the pressure accordingly. The DPI 610/615 Series pneumatic calibrator hand-pump can generate pressure from -12 to 300 psi. The volume adjuster gives fine pressure setting and the release valve also allows gradual venting for falling calibration points.
Pressure Switch Testing and Leak Testing
For switch set-up and fault finding, the display shows the output pressure and switch state open or closed. Continuity is declared by an audible signal. Verify pressure switch performance using the automatic procedure. The DPI 610/615 Series displays the switch points and the contact hysteresis. Leak test will check for pressure leaks prior to calibration or during routine maintenance. Define the test times or use the defaults and wait. The DPI 610/615 Series will report the start and stop pressures, the pressure change and the leak rate. Take a ‘snapshot’ of the working display; all details are stored in a numbered location for later recall.
Loop Testing and Fault Finding
The DPI 610/615 Series can generate a continuous mA step or mA ramp output, allowing a single technician to commission control loops. Feed the loop using mA step or mA ramp and at the control room, check the instrumentation. Use mA value for alarm and trip circuit tests. Any mA output can be set and adjusted from the keypad. The comprehensive process features aid flow and level measurement and helps with troubleshooting. Select tare, maximum/minimum, filter, flow or %span and the function will be applied to the input parameter. Save time in fault finding, by leaving the DPI 610/615 Series to monitor system parameters. Use periodic data log or the maximum/minimum process function to capture intermittent events.
Remote Pressure Sensors
By adding up to 10 external sensors (one at a time) the working ranges of the DPI 610 and DPI 615 can be extended. Modules from 1 inH2O to 10,000 psi are available to suit most applications. As a leading manufacturer of pressure sensors GE has applied the latest silicon technology and digital compensation techniques to develop these sensors.
