Description

The invention does not relate to instruments for measuring electrical magnitude: pressure, acceleration, speed of movement, and other parameters related to the movement of bodies.

Known electrons and: ical converters are non-electrically isolated, Containing a housing, the internal volume of which is filled with electrolyte: And divided by a partition in two compartments, two anodes, the cathode and sensitive elec. from the measured parameter.

The proposed converter differs from the Limit Message, that it contains a sequence with a measuring cable and includes an additional resistor and a diode, for example, an electrochemical, which allows; OL; 0; Observe L1 Non-linear characteristics;

FIG. 1 shows the practical scheme of the described converter; in fig. 2-graphs illustrating the possibility of linearization of the nature of the non-linear converter.

LrePrawler consists of glass or plastic / corus, membranes 2 and 3, inert electrodes: cathode 4 and andes 5 and 6. Membranes can be replaced by plastic plastic. Internal volume

the transducer is filled with electrolyte solution 7, which forms with the inert electrodes a reversible acid-reducing solvent; the first system. The co-nitration of o-acid ions in the electrolyte is many times smaller than the co-concentration of the reduced ions. Therefore, the current. passing through the cell. CONTROLLS only by cathode process. The ma electrodes of the converter are energized (0.8-0.9 volts) to allow the limiting diffusion current to pass through the cell. In the absence of mechanical influences on the converter's mambups, a small current passes through the cell, which is determined by the diffusion of oxidized ions into the narrow channel. In the event of mechanical effects on one of the membranes, the electrolyte solution flows through a narrow cup, and the current in the pep increases with increasing electrolyte flow rate. The co-structure of the cathode determines the nature of the dependence of the TOC, passing through the converter, on the flow rate of the electrolyte solution through the device channel and, consequently, on the measured parameter (pressure, acceleration, velocity, displacement, etc.).

Resistance R is chosen so that the voltage drop across it does not exceed 0.5 0, in this case, when the voltage of the source 8 of the power supply is 0.8 in the voltage on the elecrodes of the sensor varies from 0.3 to 0.8 in THAT provides passage through the converter. The current limit diff (|) u3ii. In connection with the fact that the voltale character is | The majority of the half-diode I diodes I range O-0.5 v. "has an expecemental character), and the plot of resistance on resistance has a power OR: a logarithmic dependence on the input parameter, it is always necessary to choose the bottom of the corresponding and Rz such that CURRENT, The passing through measure npiidoip depended almost linearly on the value of the input parameter (pressure, acceleration, etc.). On f | Ng. 2, and the dependence of the voltage U on the resistor Ri on the flow rate of the electrolyte V in FIG. 2, b is the dependence of the current / §-, (Passing through the measuring device, on the magnitude of U in Fig. 2, c is the dependence of the current / „p on the rate of flow of the electrolyte solution V. The volt-ampere characteristic of the chromo-diode in limits up to 40-50 mV are also exponential, therefore the proposed device can be used instead of a semi-aerial chymotron diode.In this case, the Rz value must be large enough so that the voltage on the .x. RMOTipOiHOM diode is not nresl (fell. 40-50 mv. Instrument for measuring mechanical BOSE actions In the absence of a mechanical effect, an inrush current passes through the converter, which is determined by the diffusion of oxide ions to the surface of the cathode. The readings of the measuring device are close to zero, and the appearance of a mechanical effect of electrolyte elongation flows from one sensor compartment in the other, n through G1Reo.b1, the current passes, increasing with an increase in speed, and overflow. Padd | Ie voltage across the resistor RI is measured in proportion to the current passing through the converter. The current passing through the measuring device / P, due to the inclusion of a diode at certain values of R, is proportional to the measured parameter of the mechanical effect (flow rate of the electrolyte solution). Subject of the Invention Electro-chemical transducer of non-Lactic values, containing corus, the internal volume of which is filled with electrolyte 1, and the partition is divided into two compartments, each containing an anode, a cathode located in the channel of the partition, two sensitive elements, hermette 1 fixed at the ends Kor-pus and measuring device, vypochechnne in the form of a constant voltage source), connected directly to the anode.m and to the cathode through a resistor, in parallel with which the electrical meter1 is turned on H1) | th device, based on the fact that, for the purpose of linearization:. |; | The characteristics of the simulator include, in it, consistently with the installation of a microprocessor, an additional resistor and a diode, Hanip HiP, Electro PM1C1C1, are included.
