INSTRUCTION MANUAL UNDERWATER PRESSURE-TIME RECORDING SYSTEM

Abstract

The equipment is a two channel recorder, complete with piezoelectric blast gauges, signal cables, preamplifier, recording apparatus, Q-step calibrator, and automatic sequence control for the quantitative recording of underwater blast pressures. It is composed of 7 basic units: (1) hydrophones and cables, (2) high input impedance preamplifier and Q-step calibrator, (3) regulated power supply, (4) sequence control equipment, (5) 1000 cycle/second tuning fork frequency standard, (6) magnetic tape recording apparatus, 0-5000 cycles/second, (7) 1000 voltamp Sola Constant Voltage Transformer.
