Fiberoptic Sensors for Non-Contact Displacement

 GENERAL SPECIFICATIONS - metric units

Standard D Models
Reflectance Dependent

The output voltage function for D model sensors includes a near side region where the voltage rises with increasing distance, an optical peak region, and a far side region where the voltage output decreases with increasing distance.  Operation in the near side region gives high sensitivity with limited operating range.  Operation in the far side region gives moderate sensitivity with greater operating range.

Range extends from 0 to the gap at which the far side output voltage is down to 10% of full scale.
Standoff equals the distance from the target to the center of the linear operating range.
Resolution (microns) = Sensor Noise(millivolts) / Sensitivity (micron/mv).
The standard sensor bandwidth is DC - 20KHz.
