Date: Monday, July 08, 2013 @ 07:00:00 EDT

OceanTools Ltd. OceanTools Ltd. have recently completed a re-design of their popular MA500 Precision Altimeter. 


DSP electronics combined with frequency swept CHIRP technology are housed in a robust hard anodised aluminium housing rated to 3000m as standard. The MA500D utilises a new, highly efficient composite transducer array enabling altitude measurement with millimetric accuracy and resolution. 

MA500 Altimiter The MA500 may be used in a wide range of harsh environment altitude measuring applications such as assisting the safe navigation of subsea vehicles, deployment of structures to the seabed and the monitoring and measurement of sediment and ice. Up to 16 Altimeters may be connected on a single twisted pair to enable the deployment of large seabed structures and multi point monitoring of large areas of interest and hazardous environments.


Up to 3 MA500s can be controlled via operator display interface, with each individual altimeter’s output colour coded for easy and accurate viewing. Outputs are viewed via multiple graphs or one single graph, with user definable sound velocity, units of measurement and maximum altitude range up to 30m.


The MA500 has various output formats including RS232, RS485, Analogue and NMEA-0183 Altitude, all outputs can be logged and replayed as required.


OceanCAM Standard Definition CameraThe new OceanCAM Standard Definition Camera is a robust, harsh environment unit utilising the latest Super HAD CCD technology resulting in very high light sensitivity combined with superior definition.


Rated to 3000m, OceanCAM is suitable for navigation, inspection and monitoring roles and is supplied in a hard anodised aluminium housing as standard. Controlled via auto select RS485 or RS232, OceanCAM has a wide range of features including:

  • Zoom, Focus, Iris, White Balance
  • Auto-focus, Auto-iris, Auto-white balance, Image Flip

  • Umbilical set-up for length, video gain and HF gain

  • Text overlay allowing 11 lines of 20 characters

OceanCAM’s highly innovative internal text overlay function allows characters to be written over the image without the need or expense of a standalone video overlay system. Text can be edited for colour, screen position and saved and deselected for later use.


The units Long-line driver will transmit the video signal up to a distance of 3000m in 100m increments and includes an HF lift.


OceanCAM is operated via OceanTools proprietary control software SmartNET. This allows the simultaneous grouping and control of various OceanTools products including: OceanCAM, PT330 electric pan & tilt and OceanLED lights. The operator can, for example, control over the same twisted pair, a group consisting of one PT330, one OceanCAM and two OceanLEDs from a single integrated operator screen.
