Analog pressure gauges are very common in industrial installations — they’ve been around for over 170 years. There are several reasons for analog pressure gauges’ popularity, including that they are relatively inexpensive, they don’t require electricity, and they can be readily used outdoors and in hazardous locations. They can be well suited for less critical applications that may only need pressure readings at infrequent time intervals. However, pressure gauges are evolving as industrial processes become more sophisticated, more precise, and more demanding. In this article we help you compare analog vs. digital pressure gauges for your application’s specific needs.
