DPI 610/615 Series is a Druck product. Druck has joined other GE high–technology sensing businesses under a new name—GE Sensing.g•Ranges -14.7 to 10,000 psi•Accuracy from 0.025% full scale (FS)•Integral combined pressure/vacuum pump •Dual readout: input and output•4 to 20 mA loop test: auto step and ramp •Intrinsically safe (IS) version•RS232 interface and fully documenting version •Remote pressure sensorsFeaturesDruck PortablePressure CalibratorsDPI 610/615 SeriesThe technically advanced Druck DPI 610 and DPI 615portable calibrators are the culmination of many years of field experience with the company’s DPI 600 series.These self-contained, battery powered packages contain a pressure generator, fine pressure control, device energizing (not IS version) and output measurement capabilities, as well as facilities for 4 to 20 mA loop testing and data storage. The rugged weatherproof design is styled such that the pressure pump can be operated and test leads connected withoutcompromising the visibility of the large dual parameter display. The mA step and ramp outputs and a built-in continuity tester extend the capabilities to include the commissioning and maintenance of control loops.Setting the Standard for Portable Pressure CalibratorsA 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 theDPI 615 to pre-defined calibration and test routines. Improved performanceThe DPI 610/615 Series combine practical design with state-of-the-art performance, summarized as follows: Accuracy0.025% FS for ranges 2.5 to 10,000 psiRanges 1 psi to 10,000 psi including gauge, absolute anddifferential versionsIntegral Pneumatic–22 inHg to 300 psiPressure SourceIntegral Hydraulic0 to 6000 psiPressure SourceMeasure Pressure, mA, V, switch state (open/closed) andambient temperatureOutput: Pressure, mA step, mA ramp, mA value Energizing Supplies10 and 24 VDC (not IS version)Data Storage92 KbytesDocumenting (DPI 615 only)Error analysis with pass/fail status and graphs.Two-way PC communication for transferringprocedures and resultsRemote pressure sensors Up to 10 digitally characterized sensors percalibratorSimplified OperationGE’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 be relied 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 MenuThe 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.Use the advanced mode for custom tasks and add to the user task menu for future use.Some of the CapabilitiesP mA V10 V*24 V*Switch°FMeasure __Source _ __P = PressureF = Local ambient temperature* = Not ISPressure Transmitter CalibrationThe 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 forloop-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.Reduce the burden imposed by quality systems such as ISO 9000, simply store results in memory and leave bothpen and calibration sheet back at the office.Pressure Switch Testing and Leak TestingFor 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 tocalibration or during routine maintenance. Define the test times or use the defaults and wait. The DPI 610/615Series 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 FindingThe 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 prehensive process features aid flow and levelmeasurement and help 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 610/615Series to monitor system parameters. Use periodic data log or the maximum/minimum process function tocapture intermittent events.Remote Pressure SensorsBy 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 inH 2O 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.Remote sensors offer a cost-effective means ofexpanding the capabilities of the DPI 610 and DPI 615, for example, in the following applications:•Low pressure•Pressure-to-pressure •Differential pressure•Wide range, high-accuracy •Test-point monitoring•To prevent cross contamination•To configure pneumatic calibrators for high pressure hydraulic systems•To configure hydraulic calibrators for low pressurepneumatic systemsDPI 615 Portable Documenting Pressure CalibratorThe DPI 615 adds powerful time saving and erroreliminating features to the comprehensive functionality of the DPI 610. These include field error calculations with PASS/FAIL analysis and two way PC communications for downloading procedures and uploading results.Reporting Errors in the FieldThe DPI 615 calculates errors and reports the pass/fail status during field tests. Problems and failures can be analyzed graphically for immediate assessment and correction. This simple to use feature reduces calibration and maintenance times and eliminates human errors.Completing the Paper TrailIt takes longer to fill out a calibration report, calculate the errors and assess the results than it does to calibrate the transmitter. With the DPI 615, documents can be quickly completed either on site or, at a more convenient time and location, by recalling the information from the DPI 615’s memory.Calibration Management SystemsWhen used in conjunction with calibration management software the DPI 615 greatly reduces the financial and resource burden imposed by quality systems such as ISO 9000. As work orders are issued, object lists and procedures are downloaded to the DPI 615. In the field these procedures configure the instrument for the tests.The errors and pass/fail status are reported and recorded in memory (as found or as left results) for later upload to the software. Calibration certificates can then be printed and plant maintenance systems updated. The wholedocumenting process is completed in a fraction of the time it takes using manual systems and without human error.For information on Intecal calibration software please visit .
