Pressure Sensor 41170 pages

Pressure Sensor 4117
is a compact fully integrated sensor for
measuring the pressure level and the water
temperature. The sensor is designed to be
mounted on the AADI SEAGUARD® using
AiCaP CANbus or as stand alone sensor using
RS-232. The sensor is easily integrated in other
measurement systems with data loggers.
Advantages:

•tSmart sensor technology - plug and play

•tDepth rating of 6000 meterst
•tDirect readout of engineering data
•tOutput parameters: Pressure, Temperature
•tSelectable interval from 1 second to 255
minutes
•tRugged and robust with low maintenance
needs
•tUse with AADI SEAGUARD® Platform
•tUse as stand-alone sensor
•tOutput formats: AiCaP CANbus, RS-232
•tUp to 60MPa range

In most measuring systems used in the sea, pressure is a vital parameter. For moored instruments
the pressure can be used for determining the
actual depth of the instrument. For instrumentation on the seabed the pressure can be used for
deriving water level. The pressure is also vital when
deriving other parameters as density and speed
of sound.
The Pressure Sensor 4117 is a compact yet intelligent sensor designed to be used on the AADI
SEAGUARD® as well as in other measuring systems.
The sensor is based on a silicon piezo-resistive
bridge sampled and temperature compensated
by an advanced Digital Signal Processor. The sensor
is housed in a rugged titanium cylinder.
Since all calibration and temperature compensation
data are stored inside the sensor, the pressure is
by default presented directly in engineering units
without any external calculation. Raw data can be
selected as additional output. Two parameters are
available; Pressure and Temperature.

The SEAGUARD® and the smart sensors are
interfaced by means of a reliable CANbus
interface using an XML based protocol (AiCaP).
The Smart sensors can be mounted directly on
the top-end plate of the AADI SEAGUARD® and
are automatically detected and recognized.
The output parameters from the SEAGUARD®
applications are easily presented in SEAGUARD
Studio.
The 10-pin receptacle in the sensor foot mates
with AADI CSP (Cylindrical Sealing plug), giving
access to RS-232 output. For connection to a PC
the Sensor Cable 4865 can be used. It is furnished
with RS-232 plug and a watertight 10-pin plug. An
additional USB plug is used for providing power.
The pressure sensor can be used as stand-alone
sensor with AADI Real-Time Collector for realtime data.
