HONEYWELL
INTRODUCES ALL-DIGITAL PRECISION BAROMETER
FOR METEOROLOGICAL AND AEROSPACE INSTRUMENTATION
New Digital Outputs Designed For Ease of Use
And System Compatibility |
| |
| MINNEAPOLIS,
Minnesota, February 10, 2003
-- Honeywell International [NYSE: HON] announced
today the Honeywell Precision Barometer (HPB)
used to measure barometric pressure for meteorological
and aerospace applications. Barometric data
computed by the HPB aids meteorologists in
making weather predictions, and aerospace
engineers in determining altitude of airborne
vehicles. |
| |
| "Meteorological
instruments are exposed to severe environments,
so to achieve the highest level of accuracy,
the pressure signals need to be temperature
compensated with electronics," said Brian
Link, Product Line Manager, Honeywell. "Honeywell's
HPB has the best combination of accuracy and
stability due to the integration of a microprocessor
with Honeywell's Micro-Electro-Mechanical
Systems (MEMS) silicon pressure sensor."
|
| |
| MEMS
devices are tiny machines, as small as 2/1000ths
of a millimeter square, which can serve as
either sensors or mechanical actuators. |
| |
| The
MEMS sensor in the Honeywell HPB is compensated
for environmental changes in temperature,
from -40 to 85 degrees Centigrade, using a
microprocessor to compute data to accuracies
within 0.03 percent of the full scale pressure
range. |
| |
| Instrument
builders in meteorology markets are increasingly
moving to digital barometers for the benefits
of ease of use, increased versatility, improved
accuracy and lower systems costs than analog
outputs. The HPB has three varieties of digital
outputs available — RS-485, RS-232 and
TTL — to provide data directly to computers
in applications such as ocean data buoys,
remote meteorological stations, airborne measurements
and weather balloons. |
| |
| The
HPB is also available in a CE (Conformité
Europeenne) mark model that meets European
Union regulatory requirements for use in high
electromagnetic field applications. |

pressure transducer products, including the
HPB, can be purchased online at www.pressuresensing.com. |
