Precautions
s INSTALLATION AND MAINTENANCE
PRECAUTIONS
Avoid mutual interference by placing sensors side by side,
more than 5 mm apart. Mutual interference occur when the
object is inclined or when sensors are mounted opposite one
another.
Do not use the sensor in the following environmental
conditions that adversely affect the sound wave transmission
through the air.
? Locations subject to air convection
? Locations with temperature differences within the sensing
area
? Rapid change in air flow within the operating range of the
sensor
Ultrasonic sensors may not be capable of detecting sound-
absorbent materials, including: cotton, powders, foam, froth,
soft porous materials, and so forth.
Condensation or drops of water on the vibrator surface of the
ultrasonic sensor may decrease detecting distance.
A 10-minute warm-up period is required from power-up to
allow the linear output to stabilize.
Clean dust off the vibrator surface of the sensor using a blast
of air or a cotton swab. Do not apply pressure on the vibrator
surface.
