Designed specifically for tight spaces, the Microminiature Gauging DVRT delivers high performance in a tiny package. A sapphire bearing and ruby ball guide the spring-loaded tip, providing an exceptionally smooth static and dynamic response. The transducers' coils and Teflon cables are sealed in vacuum-pumped epoxy, within the stainless-steel case. This provides outstanding environmental resistance. The DVRT has been successfully employed in harsh applications, including short term immersion in saline and pressurized oil.
