Supported Sensors

Hydromagic Dredging depends on sensors to get position information for angles of dredging equipment (excavator boom, stick and bucket or suction tube) and the motions of the pontoon or vessel (roll, pitch and dynamic draft). To get this information into the software, sensors have to be used which are configured using plugins.

This documents contains a list of supported sensors from each manufacturer and discusses what sensors are needed for each dredge configuration. The following brands of sensors are supported:

Cable Arm

Hydromagic Dredging ships with a plugin which makes it possible to interface with the "Cable Arm Positioning" hardware. This system consists out of a processor box with a RS232 serial connection and a CAN interface to which 3 or 4 Posital Fraba sensors are connected. This system can be used for multiple dredge configurations but was originally designed for excavators.

Level Developments

Level Developments, based in the UK and United States, sells both single- and dual axis inclinometer sensors. Models like the SOLAR-360-1-RS232 and LCH-0360 continuously output a serial data stream which can be parsed using the "Generic Inclinometer Plugin".

Posital is a manufacturer of sensors for motion control and safety assurance systems. The company’s products, which include rotary encoders, inclinometers and linear position sensors are used in a wide range of settings. Posital offers a dual axis inclinometer as well, which can be used as motion sensor on your vessel or pontoon.

When ordering a Posital inclino sensor, please make sure that you order a sensor with the Modbus RTU or ASCII interface. These models can be interfaced with Hydromagic by using either the "Hydromagic Modbus-RTU Plugin" or "Generic Inclinometer Plugin".

U.S. Digital

US Digital offers a breadth of quality off-the-shelf and custom-built inclino- and rotary sensors. Hydromagic supports the A2T product line. These sensors are connected via a RS485 style serial bus and can be addressed individually using the US Digital proprietary SEI (Serial Encoder Interface) protocol. Make sure that you order a sensor with SEI Bus interface in order to use the device with the "Hydromagic US Digital A2T Plugin".

In addition to the A2T product range, the Modbus RTU versions of the T7 product range sensors can be used by using the "Hydromagic Modbus-RTU Plugin". Make sure to order a RS485 to USB or RS485 to RS232 converter as well when your computer does not have RS485 ports installed (most likely).
