A profile projector is also referred to as an optical comparator, or even known as a shadowgraph. A profile projector is an optical instrument utilized for measuring. It is a valuable item in a small parts machine shop or manufacturing line for the quality control assessment staff. The projector magnifies the profile of the specimen, and shows this on the built-in projection screen. From this screen there is usually a grid that could be rotated 360 degrees therefore the X-Y axis of the screen could be aligned correctly using a straight edge of the machined part to analyze or measure. This projection screen shows the profile of the sample and is zoomed for better ease of computing linear dimensions. An edge of the sample to analyze could be aligned using the grid on the screen. After that, basic measurements could be obtained for distances along with other points. This is being carried out on a zoomed profile of the specimen. It could be easier and also lessen mistakes by measuring on the magnified projection screen of a profile projector.
For those who have a demand for a profile projector or optical comparator, make sure you call us today. We’ve got multiple products. These include types with manual micrometers or more recent versions with digital readouts and digital micrometers for precise and quick microscope measuring. These machines ensure fast, accurate, safe and reliable inspection of V & U notched impact test pieces.
Due to the variety of magnifications, lenses are ordered separately.
In addition, we supply V & U notch profile templates (drawings) with ISO 17025 certificates. The templates, which have a unique serial number, are calibrated to ensure that they are of the correct size before dispatch and a Certificate of Conformance is issued with each template. The use of template reduces inspection time and gives immediate idea whether notches are within tolerance.
These projectors are used in various industries like boilers, pressure vessels, metallurgy, automobiles, foundries, forge shops, steel plants, testing laboratories and similar other industries where notches of impact test pieces are required to be inspected
Notches (radius, angle & depth of notch) can be inspected easily with reliable & accurate results.
