Dual Frequency 40/200KHz Ultrasonic Transducer for Depth Measurement

1. Introduction:

The probe 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

3. Main parameters

4. Total resistance - phase curve

Wiring way:
Red - - transducer positive electrode;
Black - - transducer cathode;
Blue and green - - temperature sensor；
the yellow, white and the shield - - outer covering shield.
