Subsea Systems

Omni Instruments offers a range of products for subsea use, suitable for depths down to 4000 metres. We can supply individual components such a cable assemblies, switch units, junction boxes and housings. We also have a great deal of experience in building integrated logging and instrumentation packages to customer's requirements for the logging and display of flow, pressure, temperature, continuity, 3 axis acceleration and 3D motion & orientation.

Subsea EnclosureSubsea Housings - stainless steel housings suitable for depths to 4000 metres with optional viewing windows. Aluminium housings suitable for depths to 300 metres with optional viewing windows.

Subsea Switches - suitable for operation by an ROV, rated at up to 5 amps @ 24vDC. Depth rated to 4000m.

Subsea Proximity Sensors – switching range up to 30mm with PNP or NPN output. Depth rated to 4000m.


Subsea Pressure Sensors – ranges from 0 to 1360 bar gauge and up to 700 bar DP. Depth rated to 4000 metres. Outpus avaialble 4-20mA, 0-5v and RS485.

Some of our projects:

Subsea Data Logger

MSL1200D Subsea Logger for Pressure, Temperature and Flow
Our MSL1200D logger is a compact subsea logger with an integral display suitable for operation to 4000 metres. The unit can log multiple pressure, flow and temperature inputs, display real time readings on the integral display and store millions of readings in non volatile memory.



Subsea Depth, Load and Motion Logger

Subsea Vibration Data Logger For this project we supplied a subsea logging unit to measure and log load, depth and 3D motion of a payload as it was lowered to the seabed from a topside vessel mounted crane. A second logger was also fitted on the crane to record the motion of the crane tip, with data synchronised with the subsea load data.

Subsea Vibration and Acceleration Logger
This system was used to monitor vibration and acceleration on a subsea wave energy generator, logging readings at 1600 samples per second.

LUXUS Compact Submersible Camera
LUXUS Compact Submersible Camera
The LUXUS Compact Camera is ideal for use in diving and light ROV applications. This light sensitive camera has a fixed focal length, which can be factory adjusted to capture images at very close range. The standard lenses allow for 120° field of view in air and 90 field of view in water, different lenses are available with various angles of view. The camera housing is made from sandblasted titanium and has a depth rating of 4000 metres. Power supply 12-24vDC.
Price range : £202.22 - £990.76
MSL Subsea Data Logger
MSL Subsea Data Logger
The MSL subsea data logger is suitable for operation down to depths of 4000 metres, and can monitor up to 10 analogue and 1 serial input, plus integral 3-axis acceleration and light sensor. The logger has an internal memory capacity of 1,500,000 readings, which can be expanded with an SD memory card to over 40 million readings.The analogue input channels are user configurable to measure, voltage, or frequency. Seven of the ten analogue inputs can be configured to read frequency signals from flow meters. The serial input supports RS485 Modbus protocol which can be used to read pressure and temperature data from up to 8 of our subsea pressure sensors.
