SU1206606A1 - Arrangement for calibrating displacement transducers - Google Patents

Description

This invention relates to a measurement technique.

The purpose of the invention is to improve the accuracy of calibration.

The drawing shows a device for calibrating displacement sensors, a general view.

The device comprises a housing I, a base element. 2, in which the graduated movement sensors 3 are installed, the readout assemblies made in the form of indicators A and 5 with measuring tips 6 and 7, the stop 8, one end 9 of which interacts with the measuring instrument. tip 6, and the other end 10 - with the measuring tip 7, the mechanism 11 for setting the movement of the stop 8, the recording equipment 12.

The device works as follows.

Using the mechanism 11, the stop 8 is brought to the middle position, the indicators 4 and 5 are set and fixed at the points of contact with the ends 9 and 10 of not less than 0.15 mm, after which their scales are set to 066062

are on zero. With the help of mechanism II, the stop-8 is moved down by 50 mm. after which the indicator scale .5 is set to zero. Up to the touch with the end 9, the calibrated displacement sensors 3 with a measurement range of 0-100 mm are inserted into the housing I, fixed them and connected to the recording device 12.

 О The assignment of calibrated movements to sensors 3 is carried out in steps of 10% of their full range by means of a movement mechanism rigidly connected to ends 9 and 10,

15, while their values are monitored in the first stages using the power of indicator 5, which interacts with the end 10. When the support 8 is moved by an amount equal to

20 50 mm, the measuring tip 6 of the indicator 4 comes into contact with the end 9, while the scale shows zero, and from the sixth to the tenth stages the graduation of sensors 3

25 is produced using the indicator 5. During the whole calibration, the output signal from the sensors 3 is recorded by the equipment 12 i
