61-6029 Ultrasonic probes SC14PT-010, SC22PT-010The principle of

Ultrasonic probe is a device that emits and receives ultrasonic waves during the ultrasonic testing process. The performance of the probe directly affects the characteristics of ultrasound and the detection performance of ultrasound. The probe used in ultrasonic testing is a transducer that utilizes the piezoelectric effect of materials to convert electrical and acoustic energy.

Characteristics of SC-14PT-010, SC-22PT-010, SC-14PT-050 Ultrasonic Probes

The core of an ultrasound probe is a piezoelectric chip inside its plastic or metal casing. There can be many types of materials that make up a chip. The size of the chip, such as diameter and thickness, also varies, so the performance of each probe is different. We must understand its performance in advance before using it. The main performance indicators of ultrasonic sensors include:

(1) Working frequency. The working frequency is the resonance frequency of the piezoelectric chip. When the frequency of the AC voltage applied to both ends is equal to the resonant frequency of the chip, the output energy is maximized and the sensitivity is also highest.

(2) Working temperature. Due to the generally high Curie point of piezoelectric materials, especially when using diagnostic ultrasonic probes with lower power, the working temperature is relatively low and can work for a long time without failure. The temperature of medical ultrasound probes is relatively high and requires separate refrigeration equipment.

(3) Sensitivity. It mainly depends on the manufacturing of the chip itself. High electromechanical coupling coefficient and sensitivity; On the contrary, the sensitivity is low.

SC-14PT-010 and SC-22PT-010 are widely used in power plant raw coal plants. Especially SC14PT-010, mainly because the raw coal bunker is over 15 meters long, so there are more people using SC14PT-010. SC22PT-010 is mainly used in small warehouses, with a height of about 7 meters. The main difference between these two sensors is the size of their range, which also reflects the difference in output frequency.
