BetaGauge II.
The new industry standard
in portable pressure
calibrators is

0.025% accuracy.

The process industries are quite
literally under pressure. There’s a lot
of pressure instrumentation out there
(one source estimates nearly 75% of
all field calibrations involve some type
of pressure variable). There’s a lot rid­ing on this instrumentation — process
quality, plant safety, company profits.
And a lot of the instrumentation rides on
calibration accuracy.

That’s why we weren’t about to intro­duce just another pressure calibrator. We
wanted to develop a successor that would
significantly improve upon our own best­selling BetaGauge™. We wanted to meet
calibration requirements now and into the
next decade.

By any measure, we satisfied that design
criterion and then some. BetaGauge II™ is a
quantum leap over every other DPG on the
market. Over other pressure calibration
devices like dead weight testers. Even over
our own BetaGauge 320.

In terms of accuracy, the most critical
feature of any calibrator, BetaGauge II is
unmatched by any device in its price range.
For the majority of its available ranges, it has
a typical pressure accuracy of 0.025%
fullscale and an electrical accuracy of
±0.01%. That makes it four times more
precise than the instruments it is used to
calibrate, including 0.10% accuracy smart
pressure transmitters. Even so, BetaGauge II
is priced competitively with distant second

0.05% pressure calibrators. The closest
devices more accurate are far more expen­sive — lab instruments not intended for field
use, such as quartz gauges used to calibrate
other calibrators.

Yet remarkably, best-of-class accuracy is
but one of many reasons for specifying
BetaGauge II.

A wide range of software
makes BetaGauge II
a full-featured documenting
calibrator.

By automating pressure calibrations via a
variety of popular software packages,
BetaGauge II users can create a centralized
database for reporting and analyzing instru­ment maintenance tasks. Automation saves
time and money, while resulting in better
performing instrumentation.

BetaGauge II, like other Beta Calibrators,
is compatible with most leading calibration
management software, including ASTEC
Cornerstone™, CAL Station™ and Base
Station™, Emerson Asset Management
System (AMS™), and Honeywell
Documint™.

In addition, Beta supplies the Field
Calibrator Interface Standard (FCINTF),
which provides communications with other
FCINTF compatible software.

EC92 Compliant

The calibration data you
need. With urgency and
clarity.

The first thing you notice about BetaGauge II
is its “big screen” display. More specifically,
its 128 by 128 pixel, 63 by 63 mm LCD
display with on-demand backlighting, top
viewing angle, and per-channel display
fields. A simple-to-use membrane keypad
and a user-prompting program make
BetaGauge II especially easy to navigate.

In addition to psig, psia, and psid, read­outs are keypad selectable in any of the
following engineering units for pressure:
Kp/cm

2

; Atmos; mBar; Bar; Kpa; mmHg;
InHg; InWc 4°C, 20°C, 60°F; cmWc 4°C,
20°C, 60°F; plus one user-defined unit.
Other valuable BetaGauge II features include
minimum/maximum measurement memory,
which automatically retains the lowest and
highest values in any procedures, and %
error display, which allows difficult pressure
calibrations to be done without the need to
maintain exact or steady test pressures.

Built for punishment.
Ready for anything.

BetaGauge II is a complete pressure
calibrator. Engineered to perform in any
industrial environment. Equipped with every­thing you need for maintaining your pressure
instruments to their manufacturers’ specs.

We developed BetaGauge II as
intrinsically safe for use in Class I, Groups A,
B, C, and D, and suitable for use in Class I
Division 2, Groups A, B, C, and D hazardous
areas. BetaGauge II is built and tested with
intrinsically safe circuits and as intrinsically
safe equipment. An intrinsically safe version
is available.

Other safeguards include rugged ABS
plastic cases, ESD protection on all pins,
and EMI shielding. For optimum mechanical
strength, external pressure connection is
made by a 1/8” FNPT 316SS connector
welded to a stainless steel metal plate.

BetaGauge II is supplied with the
following standard equipment:

• A multifunction, English-language,

two-channel pressure calibrator.

• A standard voltage/current input module.

• An external battery pack (NiCad,

rechargeable).

• One set of test leads.

• A standard trickle charger.

• An instruction manual.

• A vinyl carrying case.

• A 9 pin D shell to 9 pin D
shell serial cable.

Options for BetaGauge II include:

• A 9 to 25 pin D shell adaptor.

• Additional standard input modules
(23 pressure ranges to choose from).

• Vacuum and pressure pumps.

• Quick charge battery charger/conditioner.

• Wall mount fast charger.

• CSA Exia rated intrinsically safe battery
pack.

AVAILABLE RANGES

Dual-channel operation and 24
field changeable ranges
redefine calibrator versatility.

With pressure devices of varying types and
ranges scattered throughout a typical
process plant, dedicated calibrators can get
very costly, very quickly. BetaGauge II
addresses this problem simply and sensibly.
It is both a two-channel and multi-range
device. Changing ranges is as easy as plug­ging in new input modules, which can be
done even while the unit is powered up.
BetaGauge II automatically recognizes the
signals and assigns them to the proper
channel. That versatility makes it the ideal
answer for pressure calibration, even in
critical applications like gas pipelines and
other smart transmitter-equipped sites.

There are 24 standard BetaGauge II
pressure ranges available in fully interchange­able input modules:

• 12 gauge ranges (from 0-5 psig up to

0-5000 psig).

• Two vacuum ranges (from 0 to -5 psig up to
0 to -15 psig).

• Five absolute ranges (from 0-15 psia up to
0-300 psia).

• Two compound ranges (from -15 to 15 psig
up to -15 to 30 psig).

• Three differential ranges (from 0-5 psid up
to 0-50 psid).

The standard dc module provides five
electrical ranges:

• Three voltage ranges (from 0 to ±249.99
mV dc up to 0 to ±24.999 Vdc).

• Two current ranges (0 to ±24.999 mA dc
and 0 to ±149.99 mA ).

Special ranges and calibrations are available
upon request at additional cost.

This plug-in design simplifies maintenance,
too. The base unit needs no recalibration;
only the input modules do. That means you
never have to be out of service — you send
only the out-of-calibration modules back to
the shop, while still using BetaGauge II in
the field.

Other Pressure Units (keypad selectable): Kp/cm2; Atmos; mBar; Bar; Kpa; mmHg; InWc 4°C, 20°C,
60°F; plus one user-defined unit; choice of engineering unit may be restricted by available resolution.

All gauge and sealed gauge ranges have 316 S.S. wetted parts and are compatible with media suitable
for that material. Other ranges are non-isolated and are compatible with non-corrosive and non-con­ductive gases only.

Notes: 0-7.2PSI, 0-150 PSI, and 0-1500 PSI are extended ranges. (See specifications for accuracies.)
