40-200KHZ dual frequency depth measurement ultrasonic transducer Fish Finder
1. Introduction:
The sensor used in ultrasonic detection is an energy transducer that can realize electrical and acoustic energy conversion by using piezoelectric effect of materials.The key component in the probe is the wafer, a single or polycrystalline wafer with a piezoelectric effect that converts electrical and acoustic energy into one another.
2. Application:
● locating
● Approach measurement
● escaped obstruction
● fish finder
