there are two types of pneumatic comparators. 1 is a back pressure type and the other is the flow velocity type. in back pressure type- comparators use air pressure to sense changes in dimension.

∙ 8y ago2 pressure signals are compared by being fed into 2 differnet bellows systems.
when the 2 signals are exactly equal, a balance point system will enable a beam and fulcrum system to position itself at the same relative distance to each bellows.
a pressure nozzle, which allows a portion of air supply to leak out will rest at a position;
zero point, which shows the beam is in a balance point position.
when there is a difference in the 2 input signals, this will effect the relation between the beam, fulcrum , by the input- bellows reaching a new position for each
and the movement will effect the air pressure in the nozzle line, which will be represnted at the output stage of measurement.

Where can you buy a comparator cheaply?
One can buy a comparator cheaply from both eBay and Amazon online. One can download software for them from sites such as 'ApSIC Localization Solutions.
How hysteresis comparator works?
Comparator is usually a substance which compares two quantities; one quantity is the processed one and the other is a standard value to which the processed value has to be compared. Hysteresis is a property in which the change in the magnetization lags behind change in the magnetic field. Now, Hysteresis comparator can be described as a comparator which compares a processed quantity with a quantity whose value is standard for hysteresis property., the difference being given as the output
How can an op amp comparator circuit be used for converting sine to square wave?
The wording are confusing an op-amp is an op-amp a comparator is another animal. an op-amp can be used as square wave generator by overdriving it but the results are not desirable. However a comparator will be a switch on-off at the set level.

Similarity between opamp and comparator?
A comparator is simply an opamp with a certain configuation of external circuitry ( a few components) that make it function as a comparator.
Design 2-bit comparator using gates?
2 bit comparator = 1bit magnitude comparator +1 bit magnitude comparator if A>B =A(~B)(B bar); if A<B = ~A.B; A==B = AB + (~A)(~B); block of instruction shown above is for 1 bit comparator means if A>B ==true then High bit is set on (A>B) output. if A<B true then high bit is set on (A==B) output, If we cascade two 1 bit comparator then we can design 2-bit comparator...
Difference between a schmitt trigger and an ordinary comparator?
A Schmitt trigger is very similar to a comparator -- both have analog input and send out either a "high" or "low" digital output. A comparator senses the difference between its "+" and "-" inputs. If the "+" input is even a little bit higher than the "-", the comparator sends out a "high". If the "-" input is even a little bit higher than the "+", the comparator sends out a "low". A comparator has only one threshold value. A Schmitt trigger can be built from a comparator and some resistors. Typically the circuit involves positive feedback -- attaching a resistor to feed a small amount of the comparator's output back to the "+" input. A Schmitt trigger has 2 threshold values.
