pressure calibrator

The DPI 611 is the fourth generation in the DPI

600 family, which was rst introduced in 1984. The DPI 600 family revolutionized test and calibration by providing all the tools for pressure generation and signal measurement in selfcontained portable packages. The DPI 600 soon became the industry workhorse and today it is simply known as the “Druck.”

Building on the technical legacy and more than three decades of experience in pressure measurement and calibration, the DPI 611 provides all the convenience and reliability of a true “Druck,”

yet oers twice the performance in a product half

the size.

• 50% smaller and 33% lighter than the DPI 610

• Generates 0 to 20 bar/300 psi in less than 30

seconds

• Creates 95% vacuum

• Pressure measurement is twice as accurate

• Three times better electrical accuracy

• Simplied touch screen interface with application DASHBOARD, quick TASK selection and FAVOURITES storage

• Fast, three touch set-up for any application

• Calculates PASS/FAIL errors, documents results

and interfaces with calibration software

Performance is a function of precision engineering.

The innovative design of the DPI 611 pressure

system can only achieve ecient generation and

precise control through the use of carefully selected materials with high tolerance machining and perfect

nishes.

The choice of case material and precision moulding ensures that the DPI 611 is both rugged and weatherproof.

State-of-the-art analogue and digital

microelectronics contribute both accuracy and processing power to provide a class leading pressure

and electrical capability with a unique simple-to-use

interface.

Pressure generation

With the DPI 611 you can generate from 95% vacuum to 20 bar/300 psi pneumatic pressure. A simple selector lets

you convert from vacuum to pressure and with a few stokes

of the pump, you will generate the required pressure. Fine

adjustment is made with the built-in volume adjuster and falling calibration points are achieved with the precision vent valve.

• The redesigned mechanical system provides signicantly improved performance, allowing you to generate 20 bar/300

psi while holding the instrument in one hand.

• It’s also quicker, taking just 30 seconds to generate

maximum pressure even with a one metre hose connecting the device.

• Ergonomic design, a hand strap you can position on the left or right and a soft over-moulding provide you with a rm

grip for hand-held use and prevent the instrument from sliding when on a test bench.

• The proven mechanical design provides a simple-to-use,

dependable system without the pitfalls of electromechanical devices; namely, poor reliability, regular servicing, dependence on battery condition and long pressure cycle times.

• The DPI 611 mA measurement accuracy includes one year

stability, temperature errors and calibration uncertainty, making it three times more accurate than the DPI 610 series.

• For ease of use the electrical connectors have been

rationalised to four 4mm sockets.

Truly hand-held

The DPI 611 is truly a hand-held pressure calibrator, being

50% smaller and 33% lighter than the DPI 610.

• Redesign of the pressure assembly has resulted in a more ecient and higher performance system that is both

smaller and lighter.

• State-of-the art microelectronics has reduced the size of

the PCA (printed circuit assembly) and lowered the power consumption, which in turn means smaller batteries.

• Even though the instrument is much smaller, the touch

display is almost twice as large for clear viewing and more information.

Using advanced silicon technology, the

digitally corrected “Druck” pressure

sensor achieves 0.0185% FS accuracy compared with 0.025% FS for the DPI

610/615. Taking stability and temperature errors into account over the one year calibration period, the DPI 611 is more than twice as accurate as its predecessor. This is expressed as a total uncertainty to

give you complete condence in the

measurement accuracy between annual calibrations.

Electrical capability

The DPI 611 retains the comprehensive electrical measurement and sourcing capability of the DPI 610 series, but has better

accuracy and simplied connections.

Quick-to-t pressure connections

Making a leak-tight pressure connection in the eld is inevitably frustrating. The DPI 611 comes with a quick-to-t adaptor system

that has a number of advantages over conventional methods:

• All adaptors, hoses and accessories, including the dirt moisture trap, are quick and simple to t. No tools or sealing are required

and connections are leak free.

• Damaged adaptors are very simply replaced and there’s no repair

downtime.

• Making leak tight connections wastes time and for several joints,

it takes longer than a calibration. The DPI 611 system is proven to

signicantly reduce set-up time.

Simplied touch screen

The DPI 611 uses the same interface design as the unique and award-winning DPI 620 Genii (Measures magazine innovative product of 2014).

• The DASHBOARD allows quick application selection without

menus or special keys - just tap the app.

• The TASK menu provides a library of popular congurations.

From the calibrator screen three simple gestures completely

recongure the DPI 611 for the next job.

• From the FAVOURITES menu it’s even quicker to access regularly used and customised TASKS.

• The DPI 611 touch screen only shows function keys when they’re required, making it quicker and simpler to use than complex

keypads with special function keys and key combinations.

• Application connection diagrams can be viewed on screen
