Pressure Sensors
for Barometric Measurements in Consumer Applications
The ASB1200V and T5300
pressure sensors are the world’s
most compact, fully functional
and packaged SMT barometric
transmitters. They are optimized
for absolute pressure measure-
ments of 300 to 1200 mbar.
The ASB1200V1 and ASB1200VR
sensors are gel-protected baro-
metric pressure transmitters with
a calibrated interface. They are
designed for low voltage appli-
cations. The heart of the new
ASB1200V sensors is a piezo-
resistive sensor chip, which is
mounted in hybrid technology
together with the semiconductor
ASIC. The ASB1200V1 provides
an analog output voltage of 0 to
1 V, while the ASB1200VR deliv-
ers a ratiometric output voltage.
The ASB1200V sensor’s package
features a gel-protected stainless
steel pressure port, which is
suitable for the integration in IP64
applications. Potential applica-
tions for the pressure sensors
include cameras with altimeter
function, cycling computers, gas
analyzers and meters, or HVAC
systems in buildings. Digital inter-
faces with a resolution of 14 bits
are in development.
The T5300 digital pressure
transmitter in CSMP^® (chip-sized
MEMS package) technology is the
world’s most compact packaged
sensor of its kind. It provides
a 14 bit resolution at the serial
digital interface. Together with a
GPS-determined location, the
altitude measurement permits
precise 3D positioning. Applica-
tions include navigation devices
with 3D maps. Moreover, it also
enables position information accu-
rate to within a single story of a
building for emergency calls from
mobile phones.
