|  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
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 byt the part number RPS-325-72.
Ranging Measurement
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)
