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.
