Input Parameter Pressure
Figure 3-20: External pressure sensor parameter input
gives an example of a wave & tide sensor connected to the Datalogger. The Wave and Tide sensor is
selected as
Pressure Sensor Id
and the Tide Pressure is selected as
Pressure Parameter Id
. This enables the DCPS
to calculate the depth dependent on this Tide Pressure input and other sensor input and/or the fixed settings. We
recommend using the Tide as input if available.
3.5.6
Input Parameter Air Pressure
Figure 3-21: External Air Pressure Parameter Input
Air Pressure Sensor Id
gives a list of available air pressure sensor if connected. If connected then select the
parameter under
Air Pressure Parameter Id
. Air Pressure is used to compensate for Air Pressure in calculations like
absolute pressure and absolute tide. If no sensor is selected the fixed value will be used.
3.5.7
Input Parameter Temperature
Figure 3-22: internal temperature sensor parameter input
gives an example of a temperature sensor connected to the Datalogger. The Temperature sensor is
selected as
Temperature Sensor Id
and the Temperature(Deg.C) is selected as
Temperature Parameter Id
. The
correct temperature is also necessary for calculation of the correct salinity and sound speed. If a temperature sensor is
not connected, most of the other smart sensors also has a built in temperature sensor which can be selected from the
drop-down list. We recommend using temperature from the sensor with fastest response time. The DCPS can also be
delivered with its own temperature (optional); the temperature input has to be disabled here if the built-in temperature is
going to be used.
