SU1626165A1 - Automatic two-axis recording potentiometer - Google Patents

Abstract

The invention relates to instrumentation. The purpose of the invention is to provide a time base of the measured value. The automatic dual-axis recording potentiometer includes a housing, a bracket, a feather carriage, electromechanical follower drives of the bracket relative to the housing, and a carriage relative to the crown ™ of the matte in the direction perpendicular to the direction of movement of the bracket. At one of the ends of the bracket, the means of attracting the chart paper are fixed, made in the form of a G-back plate, on which the chart paper I is fastened, and the mechanism for moving the bar in the direction coinciding with the direction of the bracket. At the other end of the bracket there is a half-lock device, which interacts with linear contact elements located along the direction of movement of the bracket. One iu of contact elements has uniformly located transversely isolated sections, and the elements themselves and the slam-shutter are included in the circuit of the electromagnetic pen elevator. 1 il. yu (L S

Description

The invention relates to instrumentation.

The purpose of the invention is to provide a time base of the measured value.

The drawing shows a schematic diagram of an automatic two-coordinate recording recorder potentiometer.

The automatic two-coordinate recording potentiometer includes a mechanism 1 for drawing chart paper, a bracket 2, a housing 3, an R-shaped bar 4, means 5 for fixing chart paper, linear contact elements 6, a slider-closure 7, a carriage 8 with a feather, connecting wires 9 , transversely isolated sections 10. The L-shaped bar 4 is provided with a mechanism I for pulling a chart paper, the torus is fixed on the L-shaped bar 4 by means of appropriate means 5, made, for example, in the form of pins. The L-shaped bar 4, together with the mechanism 1, is fixed on one of the ends of the bracket 2 and ensures that the chart paper is pulled in the direction relative to the carriage 8 with a feather coinciding with the direction of movement of the bracket 2.

The other end of the bracket 2 is secured by a slider-lock 7, which interacts with linear contact elements 6 mounted on the housing 3. One of the linear contact elements 6 has evenly spaced transverse insulated parts 10, the contact elements 6 and the slider closing contact 7 s using connecting wires 9 are included in the circuit of the electromagnetic pen elevator (not shown).

Automatic two-coordinate recording potentiometer works as follows

When the mechanism 1 is turned on, it starts moving at a given speed, the G-shaped strip 4, carrying a sheet of chart paper. At the same time, the signal applied to the input Y of the device is recorded as a function of time. If a signal monotonically varying in time is simultaneously applied to the input X of the device, then bracket 2 moves along with means of pulling the chart paper (mechanism I and P-shaped bar 4) without disturbing the time sweep of the chart paper and moving the slider-closer 7 along the linear contact elements 6. Slider-closing device 7 and the contacting elements 6 are included in the circuit of the electromagnetic pen elevator, which is in paper position if polzunok- contactor 7 is at the uninsulated portion of the linear contact element 6 and in the raised position when the one terminal of the full-zunka contactor 7 is at ka com any cross isolated

plot 10.So, recorded as a function of time on a chart paper, the signal applied to the input Y of an automatic two-coordinate recording potentiometer has gaps that can be used to judge the magnitude of the signal supplied to the input X of the potentiometer.
