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

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.
