SHADE1

Optical micrometer for online diameter measurement.

MEASURING PRINCIPLE
The laser beam for the Shade1 laser micrometers is output from the optical transmitter as a parallel aimed laser beam. The laser line strikes a CCD array in the receiving optical system. The amount of light collected by this receiver is read out and stored as a digital value in a data field.

If there is a object in the laser-line, only the receiving elements of the lines outside the shadow zone of the measurement object are illuminated. As the spacing of the pixels of the CCD array is known, the size and position of the measurement object can be determined.

The quoted technical data apply for a displacement transmitter to receiver about 800mm and a temperature of 20°C.

Display resolution of the software ≥10μm
Shadowing from ambient daylight increases the signal stability.

The controller is equipped with a display offering multicolour backlighting which changes its colour in the case of exceeding the limit value while a signal is displayed. All user selectable functions of the controller and the measured values can be viewed, displayed and stored in real time via your own web browser without additional Software.

EXAMPLE
Measurement of diameters with two Shade1 Units.
The diameter to be measured can be increased up to 550mm using the Shade2 Unit.
Laser class 1: IEC 60825-1: 2008-05
The Shade1 uses a semiconductor class 1 laser with a wavelength of 670nm. The maximum optical output power is ≤0.39 mW.
This laser class does not require any additional protection equipment.
