APPLICATIONS
he Honeywell Precision Barometer
offers outstanding value to
instrument builders requiring
accurate and stable barometric
measurements in real-world
conditions. The HPB uses proven
silicon sensor technology with
microprocessor-based signal
compensation, eliminating the need
to insulate or temperature-regulate
the barometer. The HPB has a
pressure range of 500 to 1200 hPa.
The HPA, intended for altimeter
applications, provides a pressure
range of 0 to 17.6 psia.
