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 Vmsec and with the low noise preamplifier will meet system signal-to-noise specifications. The DCVC transducer laboratory model is about complete. Author
