Workhorse Proteus

The Workhorse Proteus from Teledyne RD Instruments collects current and wave data, measurements of flow, transport, and discharge, in oceans, estuaries, and rivers.

Proteus is the evolution of Teledyne RD Instruments’ original Workhorse ADCP, which revolutionized physical oceanography, ocean engineering, and river hydrology with its acoustic Doppler technique.

Proteus can unlock a new understanding of waves, turbulence, and the changing currents below the surface. Its technical advantages deliver the most data possible with a single instrument, helping you analyze and act with ease and confidence, knowing you have gathered the best possible information about the environment.

Unique Value that Workhorse Proteus Offers: Features and Benefits

Proteus Advanced Doppler Sonar Platform (ADSP): The newest, most advanced Doppler processing platform. Enables smaller form factor. Capability for more sophisticated pinging and sampling schemes to achieve precise research goals.

Catalyst Processor: Fast processing. Easy to integrate and communicate with your electronics platform. Reliable data logging. Future potential for adding capability to the ADCP. Apps that could deliver critical real-time data.

New RDI AHRS and Dynamic Bin Mapping: Better orientation compensation leading to more accurate data and more conclusive scientific results.

Elegant Planning Software: Proteus can be used by anyone, even non-ADCP experts. Meets the needs of a workforce that is increasingly new, with diverse experience and education levels. (Traditionalists, don’t worry; it “speaks” RDI’s standard protocol too.)

Five Beams for direct measurement of ocean’s vertical velocity: Vertical profiling with high-precision velocities and high-resolution echo for sediment, biological, and wave measurement applications under wide- ranging conditions. Expands your research and collaboration capabilities.

Versatile Deployment Options: No other ADCP can match the Proteus in the variety of applications and operational needs a single instrument can serve. Time and cost savings accrue with each new project or change in deliverable.

RDI’s Broadband Techniques—robust, accepted, repeatable: Makes Proteus the instrument you can stake your research reputation on.

Multiple Communication Options—combined serial and ethernet on single instrument: Easy to integrate and communicate with your electronics platform, now and in the future.

Narrow Beam Width: Provides most robust data through higher precision and low error velocity, avoiding biases that contaminate your data.

Captive Hardware and LED: Provides reliability in rough environments. Minimizes time and stress in the field with smart mechanical design. Upon deployment, you have confidence that the instrument will work in challenging ocean environment.

20 Degree Beam Angle: Up to 33% reduction of side lobe interference. Maximizes profiling range by measuring closer to boundaries. Each ping delivers the most valid data, leading to the most swift, precise decision-making and less operational downtime.
