TheFODoptic linear position and displacement transducer is an absolute position transducer that provides highly precise position and dis-placement measurements. TheFODis the fiber optic version of the Linear Variable Differential Transformer (LVDT), but unlike it, theFODrequires no electrical signal and associated wiring. TheFODis completely immune to EMI and RFI and carries no risk of current leakage or ignition.

TheFODcan be located far away from the signal condition-er. These characteristics make theFODwell suited for difficult-to-reach locations and hazardous environments such as those containing explosive materials or prone to lightning strikes.

Our unique design is based on Fabry Perot interferometer principle. By connecting this device to one of our Fabry-Perot fiber optic readout units or dataloggers, it becomes an absolute position and displacement transducer. Its compact size, immunity to EMI/RFI, resistance to corrosive environments, high accuracy and reliability make it the best choice for linear position and displacement measurements.
