 | New developments in integrated rupture disk assemblies: Cryogenic equipment and more
Rupture disks are one-time-use membranes designed to activate within milliseconds when a pre-determined differential pressure is achieved. In one use case, they protect cryogenic systems and tanks from overpressurization. OEMs are increasingly turning to integrated rupture disk assemblies with all components combined by the manufacturer, as opposed to loose rupture disk and holder devices that leave much to chance. Learn about the latest developments in rupture disk technology.

 | All about slip rings: How they work and their uses
Rotary Systems has put together a really nice basic primer on slip rings -- electrical collectors that carry a current from a stationary wire into a rotating device. Common uses are for power, proximity switches, strain gauges, video, and Ethernet signal transmission. This introduction also covers how to specify, assembly types, and interface requirements. Rotary Systems also manufactures rotary unions for fluid applications.
