GENERAL DESCRIPTION
The digital pressure sensors in the AMS 5935 series are high-resolution 18-bit board mount sensors
which provide pressure and temperature measurement data via an I²C / SPI interface. They are
extensively calibrated and compensated, leading
to high precision and high stability measurement
data over a wide temperature range of -25 to
85 °C. With an ultra low current consumption and a
supply voltage range of 1.7 … 3.6 V, the
AMS 5935 pressure sensors are especially suitable for battery-powered applications.
The AMS 5935 combine a micromachined, high
quality piezoresistive pressure sensing element
with signal conditioning ASIC in a ceramic dual inline package (DIP) for assembly on printed circuit
boards (PCBs). Two package variants are available: one with vertical pressure ports for hose connection and one for O-ring sealing (N-package type
for manifold mount).
Multiple pressure ranges for various pressure
types are available for the sensors in the
AMS 5935 series: differential (relative) pressure
sensors in ranges from 0 ... 2.5 mbar up to
0 ... 100 mbar and bidirectional differential pressure sensors from -1.25 ... +1.25 mbar up to
-100 ... +100 mbar.
Custom specific pressure ranges or modifications
are available on request.
