Philtec's non-contact sensors provide linear position
measurements at distances from 0 to 50 mm away (2 inches).
They are intrinsically safe, very compact, and highly
accurate allowing measurements inside of mechanisms,
submerged in fluids, in hostile environments and with
targets that are impossible to measure with other sensing
technologies. We are eager to customize to your
specifications.
Two types of
fiberoptics are available:
Reflectance Dependent (D)
and
Reflectance Compensated (RC).
D models are
generally used for measurements to objects moving along the
axis of the sensor. RC models are good for single axis
measurements as well as for measurements to objects moving
past the sensor. Either type can be provided with an analog
or a digital output.
Analog Sensors are fast
responding units for dynamic applications: bandwidths
exceeding 1 megahertz are possible.
Digital Systems
(DMS) are the best choice for absolute distance
measurements, multiplexing and for process control
applications. They have a linearized RC232 output with a
5 KHz maximum sampling rate. Multiple calibrations can
be stored on-board. D and RC models available. Philtec
control software included.
Principle of
Operation....
These
sensors are reflective devices using bundled glass fibers to
transmit light to and receive reflected light from target
surfaces. The intensity of the reflected light is
proportional to the distance between the sensor tip and the
target object.
Standard
Hardware....
Standard Analog units
include the amplifier, sensor tip , 3 foot long fiber optic
cable, require +VDC input power, and provide 0 to +5 Volt
analog output with DC - 20 KHz bandwidth.
Standard
DMS units include the
amplifier, sensor tip, and 3 foot long RC fiberoptic cable.
They provide distance and reflectance data using RS-232
protocol and include AC power adaptor, keypad and display
for local operation. Can be provided as single or dual
channel instruments.
Mini-DMS units are single
channel full-featured for PC operation only.
10DMS modular multi-channel
rack accepts any combination of up to 10 Philtec DMS
type sensors.
Options...
include very small size sensor tips, connectorized tips,
right angle tips, side-viewing probes, window probes for
high pressures and vacuum, fiberoptic cable lengths up 50
Feet, ultra-high vacuum configurations, bandwidths to 350
KHz and higher, wide temperature range tips, and
resolutions as low as 2 nanometers.
Applications...include
deflection measurements, dimensional gaging, dynamic
vibration analysis, motion control, measurements in vacuum,
process control, thickness measurements, surface profiling
and so much more!
