Applications Notes
See how Philtec fiber optic sensors solve measurement challenges in aerospace, energy, cryogenics, medical technology, vacuum systems, high-pressure environments, and advanced research applications.
Pressurized Cryogenic Fluids
Philtec experience with fiber optic displacement sensors in LOX/methane rocket engine turbopump testing. Documents operating conditions in liquid hydrogen, liquid oxygen, and liquid methane at cryogenic temperatures and pressures up to 7500 psi.
Extreme High Pressure Applications
Compares three probe sealing methods for high-pressure applications: epoxy-filled tips, sapphire windows epoxied in counterbores, and brazed sapphire windows. Includes pressure window thickness formula and design factors for static, pulsing, and combined extreme conditions.
Sensors for Extreme Environments
October 2007 e-newsletter case study: three mini-DMS sensors for a 4K cryogenic imaging system measuring gap between a superconducting magnetic sensor and vacuum window. Custom brass tips, Teflon sheathing, and Fv2 vacuum feedthru in high magnetic field.
