Description
RightSound Bulletin 873E sensors are opposed mode
ultrasonic sensors consisting of an emitter and a receiver.
The receiver is microprocessor based to provide advanced
temperature stability and noise immunity. A red instability
indicator LED is used to signal the operator when an
unreliable sensing condition is present due to low or high
emitter sound levels or of adverse environmental conditions.
Green power LEDs indicate power status to the emitter and
receiver. A yellow output energized LED indicates when the
receiver output is on. Precise tuning of the receiver to the
emitter minimizes interference from ambient noise sources.
A major advantage of the RightSound sensor is the emitter
volume control. The emitter volume control allows the
operator to correctly adjust the volume for the sensing
distance (distance from the emitter to the receiver) and other
variables of a given application (i.e., target speed and
spacing, etc.). For further details on this subject, please refer
to page 4 of this document, Application Information.
The sensing of clear objects, which can be difficult to do
reliably with photoelectric controls, is made highly reliable
with RightSound ultrasonic sensors. RightSound sensors
have been designed for demanding environments, especially
those of the Food and Beverage Industry. The NORYL
housings are extremely rugged and are rated for 1200psi
washdown and NEMA 4X and 6P standards. The acoustic
faces of the emitter and receiver are made of FDA compliant
silicone rubber for maximum durability and water ingress
protection.
RightSounds require 10.8V DC to 30V DC power. Receivers
come with both NPN current sinking and PNP current
sourcing outputs. Both outputs are rated 100mA. The receiver
has the ability to operate in either a normally open or normally
closed mode. The modes are selected by the polarity of
receiver supply voltage (see Wiring Diagrams on page 2).
When the receiver is in the normally open mode, the output
conducts when the receiver hears a RightSound emitter.
When the receiver is in the normally closed mode, the output
conducts when the sonic beam from the emitter is blocked or
not present.
