Overview.... Philtec’s non-contact FIBEROPTIC DISPLACEMENT SENSORS measure distances from 0 to 2 inches away (50mm), are intrinsically safe and very compact, allowing measurements inside mechanisms, submerged in fluids, in hostile environments and with targets that are difficult to measure with other sensing technologies. Two types of fiberoptics are available: Reflectance Dependent (D) and Reflectance Compensated (RC) D models are commonly used for measurements to objects moving parallel to the axis of the sensor. RC models are good for single axis measurements as well as for m...
