GENERAL DESCRIPTION
The pressure sensors in the AMS 5915 series are
high-precision board mount sensors with a digital
I²C-interface. They combine a micromachined, high
quality piezoresistive pressure sensing element
with a modern, mixed-signal CMOS-ASIC used for
signal conditioning on a ceramic substrate. AMS
5915 sensors are extensively calibrated and compensated across a wide temperature range of
-25 to 85 °C.
The AMS 5915 come in a compact and robust ceramic dual in-line 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 (Npackage type for manifold mount). The sensors are
operational without any additional components.
The electrical connection is established via DIP
solder pins and pressure is connected either by using flexible tubing on the metal tubes or a suitable
flange.
The sensors in the AMS 5915 series are available
in various pressure ranges for all pressure types:
differential (relative) pressure sensors in ranges
from 0 ... 5 mbar up to 0 ... 16 bar, absolute pressure types from 0 ... 500 mbar up to 0 … 2 bar and
700 ... 1200 mbar for barometric measurements.
Bidirectional differential sensors are available in
pressure ranges from -2.5 ... +2.5 mbar up to
-1 ... +1 bar.
Custom specific pressure ranges or modifications
are available on request.
