Fiberoptic Acceleration Sensor

Its optical link ensures an excellent electrical insulation (greater than 65kV rms) between the sensor and the instrumentation. Its passive technology makes it ideal for shock and vibration measurements in areas where conventional piezo-electric and piezoresisitive accelerometers may create hazards to machine and personnel, and impair reliable operation. The optical sensor body is made of ceramic and polymer with no metallic elements. The optical fibers are embedded and protected by an integral 5 mm diameter thick PTFE tubing with a minimum bending radius of 80 mm. It is available in 6, 10 or 15m lengths. The sealed feedthrough connector houses the optoelectronic and conditioning circuitry. Thanks to the built-in double integrators, acceleration and displacement outputs are available simultaneously at the connector. External +24VDC power supply is required for three wire transmission.
