In most marine monitoring systems, pressure is a crucial parameter.For anchor monitoring systems, pressure can be used to measure the actual depth of the instrument, while for seabed observation systems, pressure can be used to measure water levels (waves, tides).Additionally, pressure is also a crucial parameter when used to calculate other parameters such as density and sound speed.

The pressure sensor 4117 uses a silicon piezoresistive bridge for measurement and uses an advanced digital processor for temperature compensation.The shell is a cylindrical titanium alloy shell.It is a small and intelligent sensor. All calibration and temperature compensation information are stored in the sensor. It can be directly connected to the Andra Marine Guardian platform through the AiCaP CANbus protocol. The access method is plug-and-play. After the sensor is connected, it is connected to theIt can be automatically detected and identified, and the connector is a 10-pin protective connector.The measurement parameters are pressure and temperature, and engineering data can be output directly without external calculations.

In addition, the pressure sensor 4117 can be used as a separate sensor, and can be used for real-time control and data acquisition through the Andra Real-time Collector software.Connect to the computer via cable 4865.The cable 4865 is equipped with an RS-232 connector, a 10-pin waterproof connector and a USB connector for power supply.
