Range selection (typically between 1/3 and 2/3 of the actual pressure), accuracy class, dial diameter (D), and connection thread (M20x1.5, NPT, etc.).
The main purpose of filling with silicone oil or glycerin is to provide shock and vibration resistance, protecting the internal movement and allowing the instrument to operate stably, accurately, and reliably for a long time under harsh conditions involving vibration, pulsation, and frequent starts and stops.
A stainless steel pressure gauge is a durable, corrosion-resistant pressure measurement instrument where key components (especially the case, wetted parts like the Bourdon tube, socket, and internals) are made from stainless steel (typically 304SS for the case and 316SS for process-contact parts).
It measures gas or liquid pressure and displays it on a dial, commonly using a Bourdon tube mechanism that flexes under pressure to move the pointer.
Pressure surges (also known as water hammer or pressure spikes) are one of the most common causes of damage to pressure gauges. The most effective and reliable way to prevent them is to install a pulsation dampener (snubber) directly in front of the gauge — it absorbs sudden pressure spikes and slows down the rate of change, protecting the internal mechanism from violent shocks.
The service life of a mechanical pressure gauge (such as Bourdon tube types commonly used in industrial applications) typically ranges from 5 to 15 years under normal operating conditions, but this varies widely depending on the environment, usage, and maintenance.
