The RPS-325 is a high frequency, sealed
transducer unit best suited for environments where
dirt and moisture are a problem. The transducer
head is constructed of 303 grade stainless steel
with a 302 grade stainless steel sensing face. The
remote transducer allows for mounting of the
sensor head in cramped spaces while the controller is out of the way. The ranging and proximity
modes provide the versatility of simple detection,
or actual distance measuring. The isolated form
C relay furnishes N.O. and N.C. outputs, and

with the addition of the RPS-500 card various
analog outputs are supplied. The RPS-325 sensor operates at a frequency of 150kHz for the
72" range. This sensor has a narrow sensing
beam. Sensing range available for the RPS-325 is
8" to 72". Mounting flanges, LED indicator, ranging potentiometer and 6-ft. transducer cable are
included. Optional cable lengths are available.

Proximity Detection

Ranging Measurement

Proximity detection is the detection of an object in a given
range. The detection range of the RPS-325 is controlled by the
"Range Control" potentiometer located on the front cover of the
controller. Any object within the desired range is detected, while
objects out of range are ignored. The detect point is independent
of size, material, and reflectivity. The Proximity Option is denoted
by the part number RPS-325-72.

With the addition of the RPS-500 card, Analog outputs of 0-10
VDC and 4-20 mA are provided. Precise distances of an object
moving to and from the transducer are measured via time intervals
between transmitted and reflected bursts of ultrasonic sound. The
example shows a target detected at 6 inches from the transducer and
moving to 10 inches. The distance change is continuously calculated and outputted. Ranging Option is indicated by following the
part number with (-500). (Example: RPS-325-72-500)
