Question

Difference between mechanical comparator and pneumatic comparator

Answer 1

Mechanical Comparator: It works on gears pinions, linkages, levers, springs etc. 2. Pneumatic Comparator: Pneumatic comparator works by using high pressure air, valves, ... Electronic Comparator: It works by using amplifier, digital signal etc.

Answer 2

Answer:

While the pneumatic comparator uses high pressure air, valves, back pressure, etc., the mechanical comparator operates on gears, pinions, links, levers, springs, etc.

Explanation:

Microcator is another name for a mechanical comparator. Magnification is accomplished in mechanical comparators using a variety of mechanical components and mechanical connections. A mechanical comparator is a measuring device whose mechanism is a tape spring that has been twisted and is located in the centre of the device. The mechanical comparator's central section spins over a set angle under tension as seen in the image. This comparator utilises the relative contact approach for linear measurements. The Sweden-based Johanson Company created this comparator in 1930. Mechanical comparators are available having magnifications from 300 to 5000 to 1. These are mostly used for inspection of small parts machined to close limits. A dial indicator or dial gauge is used as a mechanical comparator. A pneumatic comparator is a precise tool that uses compressed air or a pneumatic system to function. Pneumatic comparators are also used to evaluate the dimensions difference between the workpiece to be measured and the reference workpiece, much as other mechanical, optical, and electrical comparators. Compressed air or pressured air is utilised as the working medium in a pneumatic comparator. As a result, it has a number of benefits over other comparators. It is frequently chosen over other comparators because it offers several benefits.
