Analog Pressure Gauge

Product Description

Sometimes referred to as dial gauges, analog pressure gauges have a needle that directly responds to changes by pointing to numbers on a scale corresponding to the pressure sensed by the measuring element. Movement of the needle translates to variations in temperature or flow, which are easily noticed and monitored.

Most analog pressure gauges express their accuracy as a percentage of the gauge's full scale. Full scale accuracy means that wherever you are reading within the scale, the error is the same. For example, a 1000 psi pressure gauge with an accuracy of plus minus1 % of scale (ASME B40.

Readability Analog gauges are often misread due to a parallax issue (the phenomenon whereby a gauge. dial appears to the user to be in one position from one angle and a different position from a different angle) Digital gauges have a digital readout so there are no parallax problems and no counting when taking.
