Tritech PA200 / PA500 – Digital Precision Altimeters
Tritech PA200 and PA500 Digital Precision Altimeters are based on the same high performance electronics found in the well-proven, industry standard Tritech SeaKing sonar and profiler systems.
Description
Full digital synthesis of transmit and receive frequencies with greatly improved input dynamic range.
Tritech’s digital precision altimeters offer configurable design with a wide range of options available. OEM configurations include low magnetic signature rigid Delrin™ (Plastic) housings or supplied with a right-angled transducer.
Control of the altimeters may be performed in many ways including:
- Altimeter direct from a PC running DOS
- Altimeter direct from a PC running Windows
- Altimeter direct from a suitable control system
- Altimeter as part of a multidrop network
