The aim of the invention is to simplify the construction.

This goal is achieved by the fact that the U pneumatic – electric converter containing a pulse generator and a casing with two valves, the first of which is one with the input channel, and the piezoceramic membrane, the electrodes of which are connected to the output channel, have a piezoceramic membrane between the chambers and The camera is fitted with an emphasis electrically connected to the electrode of the piezoceramic membrane located

from the side of the second chamber connected to the output of the pulse generator.

The drawing shows a diagram of the pneumatic converter.

The device contains a pneumatic generator 1 of pulses, a mechano-electric node: 1 2, in which there are two chambers 3 and 4 separated by a piezoceramic membrane 5 containing electrodes 6 and 7. In the chamber 3 a metallic

0 an emphasis 8 electrically connected to the location. M from the side of the second chamber 4 by an electrode 6 of a piezo-ceramic membrane. The camera 3 is connected to the input channel 9, and the electrodes 6 and 7 are connected to the output channel 10.

P nemoelectric Converter operates as follows.

When the output signal of the generator P "I force developed by the piezoceramic membrane 5 under the influence of this

0 signal is completely perceived by the stop 8. There are no bending deformations in the piezoceramic membrane 5 and, therefore, the output voltage taken from the electrodes of the membrane is zero. When the signal P "O, the input signal causes bending of the piezoceramic membrane 5 {away from the stop 8), as a result of which deformations occur, the magnitude of which is proportional to the input pressure and, therefore,

0 on the electrodes of the piezoceramic membrane 5, an output voltage arises, the amplitude of which is also proportional to Pe. Within the limits of elastic deformations, the dependence of the output signal amplitude on pressure is linear.

5 Thus, with the same conversion accuracy as the known one, the proposed device is structurally simpler, it has no air flow through the inlet channel, since air is fed into a deaf chamber.
