Product Description
2.1
Use and Application
The UC***-F77 series ultrasonic sensors use ultrasonic pulses to detect objects. The sensor
emits ultrasound which is reflected by the object and received again by the sensor. The
measured sound propagation time is used to determine the distance to the object (pulse-echo
principle). Objects in the following forms can be detected: solid, granular, powder, or liquid. The
color and surface structure of the objects are irrelevant. Gases cannot be detected.

Example of application: film monitoring on a packaging machine
Typically, ultrasonic sensors are used in a wide range of applications including:
■
Sag control on packaging and metal processing machines
■
To measure diameter of roll material (e.g., film, paper, metal sheet)
■
To detect fill levels in tanks and silos
■
To avoid collisions with self-propelled or controlled machines
■
Height control of booms for sprayers
■
To detect containers on refuse collection vehicles
■
To detect objects or to measure fill levels on conveyor belts
■
To detect pallets on forklift trucks
■
To monitor range on barrier systems
■
To detect PCBs when feeding them to SMD placement machines
