EGE ultrasonic sensors for contactless measuring of distances are robust in design and waterproof (IP 67.) They are available for switching points from 10 to 3500 mm and are programmable as well.
Ultrasonic sensors are transmitting and receive ultrasonic signals. These signals have a frequency range from 65 kHz up to 300 kHz. Ultrasonic sensors can be used for several different applications, for example:
- Diameter detection
- Loop tension
- Height detection
- Level measuring
A short ultrasonic pulse is transmitted at the time 0, reflected by an object. The sensor receives this signal and converts it to an electric signal. The next pulse can be transmitted when the echo is faded away. This time period is called the cycle period.
- Long sensing ranges have a long cycle
periods and slow reaction time.
- Short sensing ranges have short
cycle periods and fast reaction
