Pathfinder DVL


 
General 
Product Name:Pathfinder DVL
Product Description:Teledyne RD Instruments’ new Pathfinder DVL is precisely what our customers have been waiting for! This new highly compact 600 kHz DVL is small in size and huge on value. Derived from Teledyne RD Instrumets’ long-standing, highly reliable DVL technology, this system promises to deliver the precision navigation performance you’ve come to expect from Teledyne RDI, at a price point, size, and weight that’s ideally suited for your next application.
Year of introduction:2017
System components:Patented Phased Array transducer This transducer technology allows for highest accuracy thanks to perfect orthogonality of the beams and perfect beam pointing angles. In addition to the flat face profile which are perfect for your low drag application, these arrays are insensitive to change in Speed of Sound in the water column on the horizontal axis of motion thus resulting in better positioning accuracy when used to aid a navigation system. Dual Leak Sensor These instruments include leak detection sensors: one mounted near the connector end and one mounted at the transducer end of the DVL. This feature provides the user with real-time leak detection monitoring, allowing for peace of mind and strategic decision making during critical, high-pressure missions. Transducer Health Monitor The innovative transducer health monitor provides insight, in near real-time, about the status of the transducer, and alertsthe user of potential problems. The health monitor sensor also tracks pressure cycles, maximum pressure, and operating time for quality tracking purposes.
