BG321 DUAL SENSOR,
TRIPLE DISPLAY
PRESSURE CALIBRATOR
|
 |
|
 |
 |
The BetaGauge 321 provides unmatched
pressure measurement flexibility over any competitive unit,
setting a new standard over the venerable BetaGauge 320. The
BetaGauge 321 provides 0.025% FS accuracy on both internal,
isolated, stainless steel pressure sensors. An external
pressure module connection supports all BetaPort-P pressure
modules for even greater measurement capability. A Pt100 RTD
input is provided for temperature measurements accurate to
0.1°C (0.2°F). In addition, the BetaGauge 321 measures 4-20
mA loop current and up to 30 VDC. An internal 24 V Loop
Power Supply can power a transmitter under test. The
BetaGauge 321 supports up to three simultaneous measurements
in any combination, including three pressure measurements.
With simultaneous display of two
pressure and an RTD temperature measurement, the BetaGauge
321 is ideal for gas flow (custody transfer) calibrations.
The BetaGauge 321 is available in two standard
configurations; 15 psi/1500 psi or 30 psi/3000 psi ranges,
or customized with any two ranges selected from 5, 15, 30,
100, 300, 500, 1000, 1500, 3000, 5000, or 10,000 psi. It is
also available in a Kit, which includes the BetaGauge 321
Pressure Calibrator, Pt100 RTD Probe, batteries, manual,
NIST-traceable certificate, test leads, and hard-sided
carrying case. Also available with single pressure sensor as
the BetaGauge 311.

BG PI DIGITAL
PRESSURE TEST GAUGE - SINGLE HANDED PROCESS VALIDATION
|
|
|
 |
|
The BetaGauge PI Digital Pressure Test
Gauge takes the concept of an analog Test Gauge, and brings
it to a new level, as only MARTEL can do. The BetaGauge P.I.
combines the accuracy of digital technology with the
simplicity of an analog gauge, and achieves performance,
ease-of-use, and a feature set unmatched in the pressure
measurement world. Setup of the BetaGauge P.I. is fast and
straightforward, through a menu-driven display, with minimal
text, and intuitive functions, that is simple enough to
allow the gauge to be used anywhere in the world, without
the need for multilingual displays. And the availability of
optional sanitary seals that meet 3A standards per
specification 37-01 allow the gauge to be used in virtually
any application. Ease-of-use,
performance, and features set the BetaGauge P.I. Digital
Pressure Test Gauge apart, just as you've come to expect
from Martel Electronics.

BGII PRECISION
DOCUMENTING MODULAR PRESSURE CALIBRATOR
|
|
|
 |
|
The 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 distance 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 the many reasons for
specifying BetaGauge II.
