USB Powered Fiberoptic Displacement Sensors
For The Measurement of Distance, Displacement and Vibration.
The fiberoptic probe generates an analog input signal that is sent to a digital processor where calibration data is stored on-board the sensor. The processor interpolates the calibration data table and converts the analog input into a linearized distance measure. The sensor can be gapped for measurements anywhere within the sensor’s total operating range.
Features
- Reflectance Compensated Output (see Operating Principle)
- Powered via any standard USB port, or
- multiplexed via any standard USB hub,
this sensor has - a maximum data sample rate of 16,000 samples per second
- in a 145 gram enclosure of LWH dimensions 75 x 50 x 23 mm.
- With Philtec’s fully-featured DMS Control freeware,
this sensor is a powerful solution to many measurement problems.
µDMS-RCxx – Operating Principle
- These are reflective type transducers based upon detecting the intensity of reflected light.
- RC Model sensors have a pair of fiberoptic detectors in the sensor tip.
- Light reflected off a target follows two separate paths back to the electronics where a ratiometric calculation provides the distance measurement which is independent of varying surface reflectance; i.e., reflectance compensated.

NOTES
* These specifications represent best case performance where:
- the target is flat, smooth and highly reflective
- the sensor is perpendicular to the target
- the sensor is gapped to its range of highest sensitivity (~mid-range)
- fiberoptic cable lengths are standard and the cables are not connectorized
** DMS Control Software includes a data averaging filter for averaging data samples from:
- 2 samples (the fastest rate) to 4096 samples (highest resolution).
Internally, the sensor continuously reads target data at a clock rate of 32 KHz.
ADC AVG = the number of internal readings averaged at 32 KHz clock rate before sending data out to the PC.
Samples/Sec for any ADC AVG setting can be calculated as follows:
- S/S = 32000 / ADC AVG

Cable Jacket Options
Standard
A PVC jacket over a flat steel ribbon monocoil is the standard cable sheathing, which is an excellent combination for general purpose usage.
Alternatives
Other cable sheathings are available for special applications. Interlocking Stainless Steel, Option C1, is the most popular alternative sheathing, providing the highest temperature capability and maximum crush resistance with good flexibility. It is also a good choice for high vacuum and cryogenic applications.
Notes
- Sensors with the longest cables have 2x higher noise levels.
- Please consult the factory when combining Options B, E and/or H.
