Laser outer diameter measuring instrument D22

Purpose and scope

This equipment is used to online monitor the outer diameter and ovality of cables and semi-finished cables. When the measured object is elliptical, the direction of the elliptical axis of the measured object can be determined.

This equipment is suitable for operation under the ambient climate conditions of 5 ° C to 45 ° C in the workshop.

Operating principle of equipment

The working principle of the equipment is based on the illumination projection method. The shadow of the measured object is projected on the optical ruler and is processed in the memory of the equipment to determine the position and size of the measured object irradiated by the luminous flux.

In order to determine the outer diameter, position and ellipticity of the measured object, the measuring system is composed of two mutually perpendicular light sources and light rays on the same plane with them. The optical ruler displays the cross-sectional projection of the measured object on the plane vertical axis orthogonal to the movement axis of the measured object.

The working area for measurement is a circle with an outer diameter of 17.5mm. The center of the measured object shall be as close as possible to the center of the working area. This condition shall be met during installation and use. In order to facilitate work, the outer diameter and ellipticity of the measured object with the external dimension of each coordinate can be displayed on the screen of the visualization device.

It is connected with external equipment through RS-485 or PROFIBUS DP interface (optional) to supply power and transmit data to the equipment. The measured values of outer diameter and ovality are transmitted through the interface conversion unit.

Work preparation and procedures

equipment installation 

The "D22 measuring head" is installed at the proper position of the workshop production line through a special support. It is recommended that the support base be fixed to the workshop floor through a suitable way; The connecting cable between the interface of the equipment and the computer (host control display, etc.) shall be at least 0.5m away from the power cable of the strong current equipment. The information display equipment is usually installed in the workplace convenient for the operation of employees; After installation, power the equipment through the power adapter.

Use settings

The equipment is shipped after calibration, and only the power supply and signal line need to be connected when it is used online. If the pulse counter is also ordered, it can be directly connected. If not ordered, you need to install the special setting and monitoring software that comes with the product on the customer's computer.
