What are the advantages of electric comparators?
What are the advantages of electric comparators?
The electrical comparators have a small number of moving parts hence high accuracy can be achieved. It is possible to get a very high magnification and the same instrument may have two or more magnifications, thus the same instrument can be used for various ranges.
What are the advantages of electrical and electronic comparator?
Advantages of Electrical and electronic Comparators Very high magnification possible with these electrical comparators. Less number of moving parts. More sensitive towards vibrations. The instrument is very compact in design.
What is the advantages of mechanical comparator or others?
What is the advantage of mechanical comparator over others? Explanation: Mechanical comparator is cheaper as compared to others. Mechanical comparators have more moving parts due to this friction is more and accuracy is less. External supply is not required.
What are the advantages and disadvantages of electrical and electronic comparator?
Electrical Comparator advantages, disadvantages and uses
- Vibrations are reduced due to least weight of mechanical.
- It consists of less moving parts.
- By AC supply the friction errors are reduced.
- For measuring units the indicating instrument can be held at remote locations.
What is the principle of comparator?
The general principle of the comparator is to indicate the difference in size between the standard and work being measured by means of some pointer on the scale with sufficient magnification. Initially, the comparator is adjusted to zero on its dial with a standard job in position as shown in Figure(a).
Which is the use of comparator?
A comparator circuit compares two voltages and outputs either a 1 (the voltage at the plus side) or a 0 (the voltage at the negative side) to indicate which is larger. Comparators are often used, for example, to check whether an input has reached some predetermined value.
What is the electronic comparator?
In electronics, a comparator is a device that compares two voltages or currents and outputs a digital signal indicating which is larger. It has two analog input terminals and and one binary digital output .
What are the advantages of using an electrical comparator?
The electrical comparators have a small number of moving parts hence high accuracy can be achieved. It is possible to get a very high magnification and the same instrument may have two or more magnifications, thus the same instrument can be used for various ranges.
Which is cheaper a comparator or an instrument?
These instruments are usually cheaper than other types of comparators. These instruments do not required any external source of power supply or air as in the case of pneumatic or electrical comparators. Hence outside sources do not affect the accuracy of the comparator. These installments usually have linear scale, which is easy to read.
How are vibrations reduced by an electrical comparator?
Vibrations are reduced due to least weight of mechanical. It consists of less moving parts. By AC supply the friction errors are reduced. For measuring units the indicating instrument can be held at remote locations. The accuracy of this Comparator is affected by supplying of variations in AC current.
Which is the best description of a mechanical comparator?
Mechanical Comparators are the type of comparator which is made up of mechanical means. What mechanical means? Is this is a question raised in your mind too? Mechanica Means are levers, gears, racks and pinion, such kind of means are used to magnify the movement of means to improve the accuracy of the instrument.
