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.
