Measurement Object 26.

The electronic deflection meter comprises a housing 1, in which a displacement meter in the form of a photoelectric angle transducer 8 and a recording device 16 and a transmission mechanism 5 are placed.

The photoelectric angle converter 8 is made with emitters 9, an indicator disk 10, and photodetectors 11 mounted stationary. The movable part of the angle photoelectric transducer 8 comprises a rotary axis of rotation 14. A rotary axis of rotation 14 is mounted in the bearings 15. A holder 13 is fixed at one end of the rotary axis of rotation 14.

The holder 13 is installed coaxially to the bearings 15. In the holder 13, the measuring disk 12 is rigidly fixed.

The recording device 16 is made in the form of a processing board 17 with a display 18 and with buttons for controlling the functions “on” 19, “off” 20 and “zeroing” 21. The processing board 17 is electrically connected to a power source 23 and a photoelectric angle converter 8. The recording device 16 equipped with an infrared port 22, providing remote transmission of measurement information. Information about the measured values can be transmitted through the communication connector 25 to a personal computer (not shown). The buttons for controlling the functions "on" 19, "off" 20 and "zeroing" 21 and infrared port 22 are located on the front wall 2 of the housing 1.

The power source 23 may be made in the form of an autonomous battery cell, battery, etc. The power supply of the deflection meter is carried out from the power source 23. The power supply of the deflection meter can be carried out through connector 24 from an external power source through an adapter (not shown) from the AC mains.

The pulley 4 is placed outside the housing 1 from the side of the rear wall 4 of the housing 1. The pulley 4 is fixed at the other end of the rotary axis of rotation 14.

The photoelectric converter of the angle 8 is located between the processing board 17 and the pulley 4.

The transmission mechanism 5 contains a traction element in the form of a cable 6. A cable 6, at one end, covers a pulley 4 and a locking element is attached to it in the form of a weight 7. The other end of the cable 6 is fixed to the measurement object 26.

The electronic deflection meter measures as follows.

The housing 1 of the electronic deflection meter is fixed motionless relative to the measurement object 26. The transmission mechanism 5 is prepared for measurements: one end of the cable 6 is fixed to the measurement object 26, the other end of the cable 6 covers the pulley 4, on which the locking element in the form of a weight 7 is attached and the control button is pressed function "inclusion" 19 and the control button of the function "zeroing" 21.

When deflection at the measurement object 26, the position of the cable 6 will change with respect to the photoelectric transducer of the angle 8, which will lead to the rotation of the rotary axis of rotation 14 and will cause angular movement from the pulley 4, leading to the rotation of the measuring disk 12 in the housing 1. The light flux from the emitters 9, having passed through the measuring disk 12 and the indicator disk 10, it enters the photodetectors 11 and then to the processing board 17. Thus, each value of the angle of rotation of the axis 14 with the measuring disk 12 together with the indicator disk 10 has its own combination I of the electrical signals coming from the photodetectors 11. The analog signal from the photodetectors 11 is received and recorded by the recording device 16, and the deflection value will be displayed on the display 18 of the processing board 17 with signs indicating the direction of the deflection, and can also be transmitted through the communication connector 25 to a personal a computer (not shown) or read through infrared port 22.

Power electronic deflection is carried out from a power source 23.

The implementation of the displacement meter in the form of a photoelectric angle transducer allows you to maximize

the speed of the deflection meter up to several microseconds and to increase the stability of the measurement results, which allows you to register fast processes, deformations of various structures, and expand the operational capabilities of the electronic deflection meter.

Providing the recording device with an infrared port will allow you to remotely transmit information about the measurements to user devices, the presence of a computer connector in the electronic converter allows you to transfer information about the measurements to the places where they are processed, where there is no deflection of building structures, this expands the possibilities of its application.

The execution of the processing board with a display and with the control buttons for the functions “on”, “off” and “zeroing” provides the convenience of controlling the measurement process and taking readings on the measured deflection values.

Providing an electronic deflection meter with an autonomous power source allows deflection measurements at facilities where there is no mains power supply, which increases its operational capabilities.

The placement of the measuring disk with the holder coaxial to the bearings and the location of the photoelectric angle transducer between the processing board and the pulley ensures the minimum dimensions of the design of the electronic deflection meter.

The location of the pulley in the electronic deflection meter outside the housing, from the side of its rear wall, allows measurements to be made outside the photoelectric converter and the processing board of the recording device, which increases the convenience of working with it.

The proposed electronic deflection meter was manufactured industrially at the NPF Zavod firm. It was measured that the tests of the experimental batch confirm, and this, according to the applicant, determines its compliance with the criterion of “industrial applicability”.
