How to Build a Vacuum Spring-transport Package for Spinning Rotor Gauges James A. Fedchak1, Julia Scherschligt1, Makfir Sefa1 1Sensor Science Division, Thermodynamic Metrology Group, National Institute of Science and Technology Here we describe how to build a robust spring-transport mechanism for a spinning rotor gauge. This device securely immobilizes the rotor and keeps it under vacuum during transportation. We also describe packaging that minimizes the risk of damage during transport. Tests show our design works for typical shocks during transport.
