Sustech Thermal Protectors

Pressure snubbers protect pressure gauges from the harmful effects of vibrations generated in a pressurized system? The pressure snubber works by evening out pressure fluctuations. Snubbers do not alter the pressure of the process, but lessen the pulsation in the line, thereby improving the stability of the gauge reading, while extending the effective lifetime of the gauge.

A fluid filled gauge can achieve the similar result, but some pressure systems are so intensive that you need to install a snubber in addition.
