Range 13 inches to 360 inches.
Angle of Vision The sensor views a conical area with a beam angle of 17.3° (8.6° from center
line. The diameter of the cone (d) as a function of distance from the sensor
(y) is d ≈ 0.3·y.
Sampling and Averaging 15 to 82 samples per second depending on distance between transducer
and target. In default mode, the control computes a running average of
8 samples and recognizes an out-of-range condition after 10 “misses.”
CSWIN32 software can alter these parameters within the limits of 4 to 255
to affect integration time.
Control Range The distance between sensor and target over which the control output signal
varies from minimum to maximum. With manual setup procedures, 5 to
75 inches in 5-inch increments. With computer, the user can program the
control range from 1 to 347 inches in 1-inch increments.
Resolution Basic reso-
lution of the
instrument is
±0.0068 inch-
e s ( ±0 . 1 71

(inches/µsec) as a function of temperature.
This graph plots resolution, not accuracy. Absolute distance between sens-
ing head & target can be inaccurate
(4)
. However, relative shifts in target
position will be correct within the resolution shown in the plot. Errors in
distance between sensor and target depend upon the surface of the target.
If the target surface remains constant, measurement of relative motion of
the target will be accurate within the stated resolution.
OUTPUTS
Analog:
Control Signal The principle control output is an electrically isolated dc voltage signal. It con-
nects directly to any variable-speed drive or control system. An OUTPUT ADJUST
potentiometer sets the output range from 0-1 to 0-12 volts DC. Both CONTROL
SIGNAL and JOG outputs (below) are positive with respect to COMMON.
Jog A dc voltage, set from 0-12 vdc by JOG ADJUST potentiometer provides a constant
voltage reference .
COMMON for both SIGNAL and JOG outputs is electrically isolated from earth
ground and from the 120/240 V ac power line.
