Do Pressure Gauge Accessories Affect Accuracy?

Pressure gauge accessories are essential for protecting instruments—but do they impact accuracy? In most cases, pressure gauge accessories do not negatively impact accuracy. In fact, they often improve performance by protecting the instrument from harsh conditions. In this video, we review how common accessories like snubbers, dampeners, siphons, capillaries, and diaphragm seals influence pressure measurement performance. You’ll learn when accessories enhance reliability and when they may introduce measurement error, so you can make better decisions for your application.
