how slim line tach gauges works in aircraft? - electronic board

There was a time when the diameter of the portable watch was 2 inch, up to three
A coin in inches thick.
These watches are in your pocket and are only taken out when you need to know the time.
We all know how these watches evolved, how they became thinner and thinner, and became watches.
The display meters in the cockpit of the aircraft have undergone almost the same changes, but other than that;
About Evolution time-
As the scale expands, they are getting closer to the direction of the electronic revolution, so they are no longer a smaller version of the early self, but become a thin-line digital gauge.
Of course, the sensors that actually collect the data of the aircraft engine have also been converted and began to transmit the data in the form of pulses, which can be explained by the intelligent electronic circuit inside the thin line instrument.
With little time, the integrated circuit becomes so miniature that the entire circuit is installed in a single chip in size of 2x1 cm, which is called an IC chip (
Short circuit integrated circuit).
During this period, onboard memory was developed, completely changing the way the data is processed and interpreted, as the data can now be temporarily stored, called, and used --
Almost the same memory as your calculator.
Next is a permanent memory module.
Random access memory (RAM).
Thanks to this new development, the key engine data can be stored in half when the aircraft engine is turned offPermanent Foundation
With the reduction of the internal structure of the fine line gauge in the aircraft, the front end I. e.
The display itself has changed, replacing the analog dial of the great eye with a liquid crystal display (LCD).
So now the pilot can see the actual numbers.
This is also the time when analog watches began to be replaced by digital watches.
This is also when e-pager began to appear in the market.
The next major development occurs when the memory module is connected to the panel of the fine line gauge, which completely changes the value and practicality of the fine line gauge and enhances its practicality.
Pilots can now enter alarm triggers in the form of the above limit and lower limit to directly interact with the meter.
For example, the lowest temperature and the highest temperature.
These numbers will be stored in the storage module and will be continuously compared with the input temperature data.
So if the temperature is below the minimum or above the maximum, audio-
Visual alerts can be triggered.
This means the pilot (s)
It is no longer necessary to continue to monitor the meter, but to enjoy the flight.
A piece of information is usually displayed for each thin line gauge.
So, you have a thin line meter for oil temperature, oats, RPM, voltage, manifold pressure sensor, oil pressure, etc.
As of today, a single sensor extracts data directly from the engine monitor and transmits it as a voltage through a wire to a single thin wire gauge where it means it.
The electronic board and IC circuit on the ultra-thin wire gauge interpret the input voltage, convert it into meaningful numbers, and display it on the screen.
Even if the sun is right behind the pilot, the display is bright enough to be seen.
