Tritech PA200 / PA500 Altimeters

The Industry Standard for Accurate Subsea Altitude and Distance Measurement

Product Overview 

The Tritech PA200 and PA500 are high-performance digital precision altimeters designed to provide exceptionally accurate height-off-seabed and subsea distance measurements. Built on the same proven electronics found in the industry-standard SeaKing sonar systems, these compact units utilize full digital synthesis of transmit and receive frequencies to deliver unsurpassed performance in the most challenging subsea environments.

Whether integrated into ROVs and AUVs for auto-altitude control or used in hydrographic survey suites, the PA200 (200kHz) and PA500 (500kHz) offer a highly configurable design. With the latest MKII updates, these sensors now feature built-in inclinometers for real-time slant-range correction and a "human-readable" command interface for simplified setup.

Why Choose Tritech PA200 / PA500 Altimeters?

• Millimetric Accuracy: Utilizes a proprietary signal processing engine to provide industry-leading 1mm resolution, ensuring precise positioning for critical subsea tasks.
• Frequency Versatility: * PA200 (200kHz): Optimized for longer range (up to 100m) with a wider 20° conical beam.
  • PA500 (500kHz): Optimized for high-resolution, short-range work (up to 50m) with a narrow 6° conical beam.
• Integrated Inclinometer (MKII): The latest version includes internal pitch and roll sensing, allowing the device to automatically compensate for vehicle tilt and provide a true vertical altitude (slant-range correction).
• Calibration-Free Deployment: Fully software-configurable and factory-calibrated, these units are ready for immediate "plug-and-play" operation via Tritech’s Seanet Pro or AltTest software.
• Rugged & Depth Rated: Available in various housing materials (Acetal, Stainless Steel, or Titanium) with depth ratings ranging from 700m to 6,800m to suit any mission profile.
