Angle
The inclinaon of the object’s surface in relaon to the sensor face will aect
the strength of the reected sound waves. Surfaces perpendicular to the
sensor will reect more signal directly back to the sensor. If a surface is more
than a few degrees o perpendicular, enough of the signal will be reected
away from the sensor that the target will not be detected. Generally speaking,
a target angle greater than 5 degrees o perpendicular will not be detected.
The target angle becomes increasingly crical as the distance to the target
increases.
Environmental Condions
Temperature, humidity, vapors, dust, and pressure can aect the sensor’s
performance. APG ultrasonic sensors are designed to compensate for many of
these condions. However, if the condions are extreme, sensor performance
can be degraded enough to require the use of a longer-range sensor than
normal condions would require. Ultrasonic sensors may not be suitable for
applicaons with heavy chemical vapors (such as solvents or gasoline), heavy
dust or when signicant surface foam is present.
