DatenblattDPI610/615 Series – Documenting Pressure Calibrator
The DPI610/615 Series is a product by Druck Ltd.
Druck is now part of GE Sensing – a merger of leading measurement technology manufacturers.
The series was specifically developed for on-site maintenance and calibration of pressure sensors and transmitters.
Product Description
The documenting pressure calibrators DPI610 and DPI615 are designed as portable, self-contained instruments.
They feature an ergonomic hand pump for pressures up to 20 bar, a fine adjustment valve for precise setting, and a switchable vacuum generation up to –800 mbar.
Key features include: 2-wire loop power supply, calibration data storage, multimeter functionality, and real-time error calculation (on DPI615) for enhanced user benefit.
With the optional Intecal software, users can create calibration procedures and reports.
After calibration, measurement data can be stored or exported to a PC – including a calibration certificate.
Superior Specifications
The DPI610/615 Series offers extensive, field-proven measurement capabilities:
- Accuracy: ±0.025 % FS
- Pressure ranges: internal 0–20 bar to 400 bar, external up to 700 bar
- Fine adjustment: manual with control valve up to 0.01 mbar
- Display: simultaneous indication of setpoint and measured value
- Data storage: up to 1000 data sets
- Interfaces: RS232, PC data transfer
Easy Calibration
The mode menu is the core of the operation.
Modes such as transmitter simulation, switch test, and leak test can be selected at the touch of a button.
The instruments are equipped with robust pneumatic and hydraulic components, ensuring reliable performance even in harsh environments.
ATEX-certified versions minimize risks in hazardous areas, eliminating the need for extensive approvals.
Operating Modes
A dedicated function key provides direct access to all operating modes.
In the “BASIC” mode, the DPI610/615 can even simulate its predecessor, the DPI601.
The ergonomic housing with a central handgrip allows easy pumping while the unit remains stable on the surface.
Transmitter Calibration
In P–I mode, the calibrator simultaneously displays output pressure and loop current.
For transmitters with percentage indication, the test range can also be scaled in %.
The hand pump generates pressures from –850 mbar to +20 bar; the fine volume adjuster enables precise control and venting.
Pressure Switch Testing & Leak Test
The DPI610/615 can fully test pressure switches.
The display shows output pressure, switch status, and contact resistance to determine opening and closing pressures.
During leak tests, the test object is checked for leaks, and the calibrator displays both pressure drop and leak rate.
Loop Test
Programmable current values can be output as step sequence (mA-STEP) or ramp (mA-RAMP).
This allows the calibrator to simulate transmitters or verify control loops.
Additional functions such as tare, low-pass filter, flow, and percentage display are also available.
Data Management
All calibration results are stored internally to meet quality standards such as ISO 9000.
Notes and manual recordings are unnecessary – everything is digitally documented.
External Reference Sensors
By connecting up to ten external sensors (one at a time), the measurement ranges of the DPI610 and DPI615 models can be expanded flexibly.
Suitable sensors cover ranges from 2.5 mbar to 700 bar, making them ideal for almost any application.
As a leading pressure sensor manufacturer, GE uses the latest silicon technologies and digital compensation techniques for these sensors.
Applications for External Reference Sensors
External reference sensors can extend the measurement range of the integrated sensor in the DPI610/615 cost-effectively – for example, in the following applications:
- Low-pressure measurements down to the mbar range
- Testing pneumatic pressure transducers
- Differential pressure measurements
- Calibration of narrow pressure ranges with high accuracy requirements
- Applications requiring minimal dead volume
- Expanding pneumatic calibrators for hydraulic systems
- Expanding hydraulic calibrators for pneumatic systems
Calibrating and Documenting with the DPI615
The DPI615 enhances the comprehensive functionality of the DPI610 with advanced data management.
This includes real-time error analysis during calibration and a procedure memory for predefined calibration routines from calibration software such as Intecal.
On-site Error Calculation
In calibration mode, the DPI615 directly displays the measurement error of the device under test – including pass/fail status and graphical error indication.
Adjustments or recalibrations can be carried out immediately on-site without transporting the unit back to the workshop.
Calibration data can then be easily transferred to a PC.
Simple Documentation
Calibration reports can be completed directly on-site using the values measured by the DPI615.
Even more convenient is the upload to the Intecal software, which allows automatic printing of a calibration certificate.
Working with Calibration Software
The combination of the DPI615 and Intecal significantly reduces workload within the quality system, while improving accuracy and traceability of documentation.
Calibration procedures are created and stored on a PC, then executed on the DPI615 at the press of a button.
After completion, the user can upload data directly to the database and generate a certificate.
The display’s info line shows calibration status (e.g., “after adjustment”) in real time, ensuring full process transparency.
The fully digital documentation replaces manual paper protocols and minimizes input errors.
A free demo version of the Intecal software is available for evaluation.
Scope of Delivery
The DPI610/615 units are supplied with a carrying case, test leads, user manual, and a calibration certificate with data.
The DPI610/615 HC model additionally includes a 250 ml polypropylene fluid reservoir and a filling hose.
Traceability
GE instruments and calibrators are calibrated using precision pressure standards and are traceable to international standards.
