Explosion-Proof

The RPS-326 is a low frequency, sealed
transducer sensor best suited for applications
where harsh or hazardous environments are a
problem. The transducer head is constructed
of 316 grade stainless steel and has a CSA
explosion-proof rating. The RPS-326 sensor
head CSA rating is Class 1, Division 1, Group
ABCD. 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-326 sensor,
which operates at a frequency of 37kHz, has a
narrow sensing beam. Sensing ranges available
for the RPS-326 include 24" to 72", and 24" to
240". Mounting flanges, LED indicator, ranging
potentiometer and 30ft. 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-326 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-326-72.

With the addition of the RPS-500 card, Analog outputs of 010 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 feet from the
transducer and moving to 10 feet. The distance change is continuously calculated and outputted. Ranging Option is indicated
by following the part number with (-500). (Example: RPS-32672-500)
