For the Past 50 Years, Open-Ended Coaxial Lines Were Commonly Employed for the Determination of Electromagnetic Properties of Various Materials. in This Article, the Application of an Open-Ended Hollow Coaxial Cable Resonator (OE-HCCR) as a 1-D Inclinometer for Tilt Measurements with 110 Nanoradian (Nrad) Resolution is Proposed and Demonstrated. the Coaxial Cable Resonant Structure is Formed between a Metal Post Welded within the Coaxial Cable at the RF Input End and the Open End of the Coaxial Cable. a Metal Mass Block, Suspended in Proximity to the Open End in Parallel is Used to Construct a Pendulum Structure, Serving as …

This Article Reports a Novel Self-Compensated Inclinometer with a Wide Dynamic Range and High Measurement Resolution based on Two Hollow Coaxial Cable Fabry-Perot Resonators (HCC-FPRs). the HCC-FPR is Formed between a Metal Post that Shorts the Inner Conductor and the Outer Conductor of the HCC and the Water Level Inside the HCC. Changes in Tilt Angles Result in Variations of the Water Level in the HCC, Leading to Changes in the Cavity Length of the HCC-FPR. by Tracking the Shift of the Resonance Wavelength of the HCC-FPR, a Single HCC-FPR Can Be Used as a Sensor Device for Tilt Measurements. …
