Modeling Simulation and Fabrication of Fiber Optic Pressure Sensor Probe
Elastic element mechanical pressure gages consisting diaphragm are basically used for the differential pressure measurement. In FODPS, diaphragm acts as a reflector. A flexible disc of plastic is used as a diaphragm to convert the measuring pressure to the deflection of diaphragm. Concentric corrugations are designed to linearise the deflections according to pressure. Reference and measuring pr...
متن کاملFiber-Optic Measurement Systems: Microwave and Radio Frequency Heating Applications
EOAF 12004160 65 66 67 68 69 70 71 Abstract Fiber-optic sensors do not interfere with electromagnetic fields and are commonly used to measure temperature and pressure used in microwave and frequency heating research and applications. This article introduces the physical principles for three different types of commonly used fiber-optic sensors and discusses important parameters to be considered ...
متن کاملRf and Microwave Fiber Optic Delay Line Techniques
Other delay line techniques include energy transfer methods such as crystal or glass substrates that generate acoustic waves. Here, electrical energy is converted to mechanical energy using a transducer. The energy moves through a medium at a speed related to properties of the material used to construct the delay line. Specific geometries of crystal or glass result in longer delays due to inter...

متن کاملOn fiber optic probe hydrophone measurements in a cavitating liquid.
The measurement of high-pressure signals is often hampered by cavitation activity. The usage of a fiber optic probe hydrophone possesses advantages over other hydrophones, yet when measuring in a cavitating liquid large variations in the signal amplitude are found; in particular when the pressure signal recovers back to positive values. With shadowgraphy the wave propagation and cavity dynamics...
