An analog device or analog technology is comprised of a machine and a media readout that transmits continuous interpretable data regarding the functioning and output inherent to the machine’s purpose.
Analog in most cases is dependant on a mechanical linkage. Example: Before cars had digital readouts of the odometer, the measurement was relayed by a mechanical counter that was paired mechanically to the rotation of the car’s wheels.
Analog technology is becoming a fallback system as software digital systems are applied to old measurement points.
Another example of analog technology might be an alarm clock that is mechanical. (You have to wind up a spring to power it) The face of the clock is the display of the time which is denoted by the positions of the two clock hands. Digital clocks display time-based on the output of an electronic timer circuit. The display is in a numerical form that is reliant on the timing circuit.
In industrial settings, there are still many analog devices that are standard. Pressure gauges, , dispensing meters, and even scales are still analog but do have digital counterparts.
Analog technologies are still relevant and as a backup is without equal when there is a power outage. This is particularly true in oil depots, and power plants where there is no shortage of pressure gauges that need to be monitored.
