PRESSURE PULSE GENERATOR FOR DYNAMIC CALIBRATION OF PRESSURE PICKUPS Russian patent published in 1994 - IPC

FIELD: instrumentation engineering. SUBSTANCE: generator has storage capacitor bank 1, two controlled dischargers 2, dumping resistor 3, peaking capacitor 4, and set of T-shaped electrodes 5, 6 which are essentially shaped plates installed on working surface of dielectric plate 7, and annular copper electrode 8 placed on underside of dielectric plate. Electrodes 5, 6 and 8 are positioned on plate so that relative coverage is ensured when electrodes are aligned in one plane; high-voltage electrode 5 and grounded electrode 6 are relatively opposite on annular electrode projection onto plane mounting electrodes. EFFECT: simplified design of generator, enlarged peak-to-peak range. 3 dwg
