Description

(54) TOOL FOR MEASURING SMALL

DISPLACEMENT

the converter is connected to the voltage source ill.

FIG. 1 2 shows block diagrams of two device variants.

The device contains sensitive

Element | 5ent 1, holder Z, measuring circuit 3, block 4 of the Pereshmotsen recording, node 5 for adjusting the position of the sensitive element, made in the form of a ferroelectric disk 6 {Fig. 1) or an electromagnet 6 (Fig. 2), a voltage source 7 (Fig. 1) or a current (Fig. 2).

The device works as follows. After installing element 1 with node 5 (adjusting its position on holder 2 to the operating voltage source 7 or current, a number of known positions of element 1 are set, at which unit 4 registers the amount of signal measured; | 3 circuit, i.e., the device is calibrated | arbitrarily.The dependence of the position of the sensitive element: 1 on the magnitude of the source signal 7 is set to 0 {i lBaptFreiibRo when removed from the device under test device With or during reputable processes, the displacement of the ashe calibration signals can be resolved: during short recessions of the IBOB. It is not only the connection between the source 7 and the position that is established;

element 1, non-frequency characteristic of the node 5 p) beating its position.

The device calibrates at a distance in any operating conditions, including hardness, aggressiveness of the medium, vibrations and d blows, as well as immediately before the measurement, immediately after it or even during the measurement. All this increases the accuracy of measurements.
