Ultrasonic emitter

The main performance indicators of ultrasonic sensors Ultrasonic probe is the core of its plastic jacket or metal jacket in a piezoelectric chip. There are many materials that make up the wafer. The size of the wafer, such as its diameter and thickness, varies, so the performance of each probe is different and we must know its performance before use. The main performance indicators of ultrasonic sensors include:


1, the working frequency.

The operating frequency is the resonant frequency of the piezoelectric wafer. When added to both ends of the AC voltage frequency and the resonant frequency of the chip equal, the maximum output energy, the highest sensitivity.


2, working temperature.

Due to the Curie point of the piezoelectric material is generally relatively high, especially when the use of diagnostic ultrasound probe less power, so the working temperature is relatively low, you can work long hours without failure. Medical ultrasound probe temperature is relatively high, requiring a separate refrigeration equipment. 


3, sensitivity.

Mainly depends on the manufacture of the chip itself. Electromechanical coupling coefficient, high sensitivity; the other hand, low sensitivity.
