TARGET CAPACITIVE TRANSDUCER FOR FUSE Russian patent published in 2011 - IPC F42C13/00 

FIELD: weapons and ammunition.

SUBSTANCE: proposed transducer comprises power supply circuit, circuit to protect against spontaneous operation connected with power supply and comprising RC-circuit, two isolated electrodes that, together with constant-amplitude variable-frequency square pulse generator are incorporated with the circuit sensitive to capacity change between electrodes connected to detector of pulse generator signal. Said detector is connected with comparator. Note here that comparator is connected with actuator. Note also that signal detector circuit incorporates frequency detector with its output connected to comparator via LF output signal voltage amplifier that comprises narrow-band filter. Note here that actuator is connected with circuit protecting against spontaneous operation wherein RC-circuit is made up of integrating link and comprises, at least, one locking transistor switch.

EFFECT: expanded performances, higher noise immunity and stability.
