Maybe you have heard about 3 axis load cell right now and are ondering just how they work? How in the heck can a magnet function to discover the speed of something? If this does, what on earth does the magnet focus onto operate, because after all magnets react to ferrous metals like iron and steel.

When someone is speaking about a magnetic speed sensor, whatever they are really discussing is really a hall effect sensor. While they are normally found in such systems as anti-lock braking systems in cars, they are in common use within numerous hi-tech systems and machines which require the use of electronic transmission of speed or RPM data and knowledge.

They get their name for the Hall effect that was discovered with a man called Edwin Hall in 1879. In short, is refers to an electronic phenomena that is certainly created on the opposite sides of an electronic conductor when a digital current is flowing through it while a magnetic field is used perpendicular to the present.

Maybe you have stopped to wonder how gages and sensors in rocket engines work? Man, those engines and all things in them must get hot! So why doesn’t the whole system go haywire when all of the finite mechanisms such as speed sensors that gage the rotation rate of all the different spinning motors get hot enough to melt common metals.

Well it will be easy to guess they make everything away from miniature load cell. Hey! What about electrical components which contain finite moving parts? Won’t everything short out and how about metal expansion in high temperatures? The reality is, that all of these problems happen to be solved by using new high tech materials.

To start with, high temperature sensors use magnets or silicon strips impregnated with magnetic material to really gage how quickly something is spinning, to ensure that eliminates any type of cable that could foul up in high temperatures. So, this eliminates one problem but how about thew others?

Ceramics Replaces Metal in High Temperatures. Ceramics are used extensively in high tech, high temperature speed sensors and when fact ceramics are discovering their way into many high temperature mechanical applications. Its hard, expands minimally, can be shaped and milled and doesn’t conduct electricity and withstands extremely high temperatures, so ceramics rocdlr great in high temperatures.

For wiring, copper which melts at about 2,000 degrees is replaced by new hi-tech alloys that endure higher temperatures. Rather than plastic coating, like regular wire, other high tech heat resistant materials including asbestos are used to insulate the wiring in today’s high temperature speed sensor

While that is a mouthful to comprehend, in layman’s terms it allows for mechanisms to be utilized to really calculate the pace of something using electricity instead of a cable and gears. However; there should be ferrous metal components of the program for the magnets in the sensors to pay attention to. For example, load cell, such as is at use in anti-lock braking systems works with a gear for the sensor to concentrate on and tracks the rate of the passing gear teeth to produce data which is delivered to the main factor that regulates the entire anti-lock braking system.
