The RPS-401A, RPS-426A analog ultrasonic
sensor is mounted in a barrel housing and is completely
self contained. It is powered by 20-30VDC and is reverse
polarity protected. It also has a narrow beam angle which
enables it to get into tight places. A flat target can
tilt up to 8 degrees and still be detected. The RPS-401A,
426A has 2 short circuit protected analog outputs, 4-20mA
and 0-10 VDC. These outputs can easily be inverted and
can be scaled over almost any range by means of adjusting
the zero (P1) & span control (P2). For set-up purposes
an LED strength indicator is provided. This LED is Green
when not detecting and fades to Red as a target moves
into place, depending on how much reflected signal is
coming back from the target. The frequency of operation
for the RPS-401A is 212kHz for the 4" to 40"
and 150kHz for the 8" to 80". The RPS-426A has
a 8" to 80" range and operates at a frequency
of 150kHz. The RPS-401A barrel is constructed of plastic
valox, and the RPS-426A is Stainless Steel. The barrel
measures 30mm x 100mm. A standard 6' cable is provided.
An optional quick disconnect plug is available. |
