Topic: What are different MultiCheck Comparators?
First of all, what is a Comparator?
Multicheck Comparator is one types of comparators.
Multicheck comparator is meant to inspect the multiple dimensions of an object at the same time. This is very helpful while inspecting relative dimensions. ( Example: Diameter of a bore and its concentricity). So multicheck computer is used to check multiple measurements.
There are different types of multi-check comparators are available. They are listed below
- Electrical Multi-check Comparators
- Air Multi-check Comparators
- Air-Electric Multi-check Comparators (Combination of ‘air-electric’)
Electrical Multicheck Comparators
There are electric heads used to check the dimensions in electrical comparators. Electrical multicheck comparators are used a number of the electric-check heads to check multiple dimension in a part.
In each measuring head, there are some signal lights which represents whether the dimension is a correct size or oversized or undersized. There is only one signal light which will collect all the other light signals of various dimensions and if there is any deviation from the working standard, the master light represent there is a deviation by examining the other light signals.(See the Flowchart)
This type of Multi-check comparators is widely used in the mass production lines.
Air Multicheck Comparators
Group of Air comparators are used in Air multicheck comparators. This is also similar to the above electrical multicheck comparators
With Air multicheck comparators it is easy to check diameter and concentricity at a time. This is the advantage over the electrical Multichek comparators.
Air-Electric Multi-check Comparator (Combination of ‘air-electric’)
While checking measurements of an object having multiple dimensions, the Diameter and concentricity will be measured with the air comparators and the remaining dimensions will be checked by the electrical comparators.
These are the different types of multicheck comparators are available.
