Imaging frames made by Pero-System are used for the reliable and accurate measuring of objects. Depending on the measurement requirements, they form an imaging curtain or a grid and can be combined in a variety of ways. All systems comprise an object holder and a frame, which is often moved manually on a rail. Depending on the model, the frame has a different clear width. Fig. 1 shows a typical application. During measurement the frame is moved on the rail across the object to be measured. The volume of the object is determined.

Fig. 1: Measuring the volume of a wooden trunk (Table 1, model 351 NT, 352 NT and 2 x 353 NT)

Fig. 2: Measuring the volume of parcels ((above) and Demonstration video (below)

In other applications the frame is moved over objects like packets or parcels. Again, the frame determines the diameters and the volume of the objects. In another configuration, the objects are pushed through the frame by a conveyor belt.

Both options are also available with a rail allowing a vertical movement of the imaging frame. In this option the weight of the frame is balanced so that it hangs quietly in each position.

In a high resolution option (see Fig. 3) an object of circular or elliptical cross section area is placed within the frame, which hangs quietly and determines the circumference of the object every 2 seconds. This option allows to measure the change of the diameter or of the circumference of the object, e.g. due to a temperature change (see Fig. 4). Changes as low as 20 Micrometers are detected.

Pero system measuring frames can also be programmed as fast counters for free-falling objects.The counting rate depends on the size of the objects and the desired monitored area of the measuring frame. Please ask for details. The video below shows an example of counting free-falling screws.



The following table 1 shows the imaging frames available (column 1). Typical rails and object holders designed for the imaging frames can be found in the same row.

Note that our industrial scanners are not intended for the use as medical devices.
