Description

one

The proposed invention relates to the field of measurement technology and can be used for the calibration of strain gauge strain sensors.

A device for calibrating strain gauge strain sensors is known, comprising a housing, an “aggregator, fixed in a housing on its lateral side, and strain gauges.

Calibration of strain gauge strain gauges on this device consists in determining the relative elongation of the strain gauge glued to the beam, depending on its deflection.

However, this device allows to produce the calibration of strain gauges only in the zone of elastic deformations.

The purpose of this proposal is to obtain deformations of tension and compression not only in the zone of elastic deformations, but also outside it, which improves the measurement accuracy due to the fact that the device is equipped with a pull connected at one end with a loader, two directions with grooves, mounted on the opposite side of the load, one ends of which are fixed to the hull base, while others interact with the free ends of the grating, the third guide, which is placed perpendicular to the first two and passing through the slots in them The pin of which is fixed on the side of the case,

and the other on one of the guides, and a pack of plates interacting with the guides, and the strain gauges are pasted on the patorna of the pack of plates.

FIG. 1 shows the described device, a plan view; in fig. 2 - the same, side view.

The device contains a package of rectangular steel plates /, body base 2, coupling stand 3, horizontal guide 4, bracket 5, support flange 6, screw 7, t tu 8, four axes 9, stop W, two vertical guides 12, the slider 13, strain gauges strain 14, the upper slider 15, the fastening bolts 16, the nuts 17 and the nuts with the axis 18.

A device for calibrating strain gauge strain sensors works as follows. The stack of steel plates / is compressed evenly between the base of the body 2 and the horizontal guide 4 with the bolts 6 and between the two vertical guides 11 and 12 so that there is no gap between the plates of the stack. Rotation of the screw

7, a nut with an axis 18 is screwed onto it, which does not follow the tie rod 8 and causes the guides 11 to rotate. 12 around the four axes 9 and n-tilt parallel to each other. Tilting, the guides 11 and 12 cause the evenly displaced mutually

Steel plates of package 1, stretching and sticking on their ends are tens-metric strain gauges.

Subject matter

A device for testing, for example, defo, rmc | ii, load cell, comprising a housing, a loader fixed to a corus on its side, 1 and a ten watcher, characterized in that it is equipped with with its end with a loader, two guides with grooves installed on the opposite side of the loader, one ends of which are fixed to the base of the corulus, while others interact with the free ends of the r, the third rail placed perpendicularly to the first two and passing through the grooves in n, they, one end of which is fixed on the side of the corps, and the other one of one of the nazravlivayuschie, and plate pack, interacting with controllers, and strain gauges are glued on the ends of the plate pack.
