Development of LP Wave Discrimination Capability Using LP Strain Instruments.
Abstract
The development of a design for a three-component strain-inertial complex is progressing according to schedule. Two types of primary transducers (5 x 10 to the minus 13th power strain sensitivity) are being considered - a moving coil and a direct current variable capacitance (DCVC). The moving coil transducer has a generator constant of 31,600 V/m/sec and with the low noise preamplifier will meet system signal-to-noise specifications. The DCVC transducer laboratory model is about complete. (Author)
