We may be living in a digital world, but analog is here to stay. Analog devices are still used for many applications. Consider, for example, the industrial gauges that measure numerous process variables like pressure, temperature, and flow. Sure, these meters could be replaced with digital versions, but in many cases that would be very costly to do. Moreover, the mechanical nature of analog gauges is desirable under some circumstances — no power supply or battery replacement is required for their operation. But in any case, analog meters do miss out on many of the benefits that come along with their digital counterparts, like remote monitoring. When analog meters are in use, humans have to physically check them to ensure that everything is operating normally.
