The advantages of an analog hydraulic pressure gauge.

The pressure gauge is the measuring instrument used to monitor the pressure of a fluid, water or air, in order to avoid damage or malfunctions of the hydraulic systems.
There are several types of pressure gauges to choose from, although the first distinction concerns two categories: the digital hydraulic pressure gauge or the analog pressure gauge. The difference depends on the type of sensor, piezoresistive in the first case and mechanical in the second.

In this regard, it is good to consider that the analog gauge is the most widespread on a large scale, precisely because it has two great strengths. The lower cost compared to the digital one and a great practicality which translates into both ease of reading and being able to be installed anywhere without requiring an electrical power supply.
