Section 1. Overview
The PSA-916 is a microprocessor-controlled, self-contained, underwater
acoustic product. It generates a narrow beam acoustic signal and
measures the travel time for the signal to bounce back from the target
surface. The unit provides range data in both analog and digital formats
for analysis and process control.
The PSA-916 is housed in a corrosion-resistant anodized aluminum
pressure case. It is O-ring-sealed and rated for operation in water depths
up to 2,500 meters. The external 6-pin connector provides connections
for external power source input, external key source input, analog and
RS-232 output.
