People Also Ask:

What is the lifetime of the transducer?

Depends on the quality of the transducer. All knmtech’s transducers are highly processed and adopt superior PZT ceramics. And the warranty of the transducers is one year.

What is the structure of PZT transducer ?

The transducer consists of a housing, a matching layer, a piezoceramic disc transducer, a backing, an outgoing cable, and a Cymbal array receiver.

How to check an ultrasonic transducer?

1. Use an impedance analyzer for professional parameter frequency detection; check whether the transducer parameters match the parameters of the ultrasonic generator and whether the ideal effect can be achieved. Improper transducers can cause damage to the product and damage to the machine.
2. It can be identified from its production process and appearance: it directly reflects the importance that technology attaches to the quality of products, and the quality of products with good technology and appearance will naturally be better (in most cases).
3. On-board inspection:
(1) Overload operation test: test the stability and life of the transducer quality. This test only requires continuous and uninterrupted operation of the rated load for 8 hours.
(2) Power output test: it can detect the matching of the transducer and the ultrasonic generator, and can reflect the power output of the generator box and the load of the transducer.

What are piezoelectric ceramics?

We know that ceramics can be considered as insulators. So we plate one side of the ceramics with silver and add a copper sheet to the other side, which becomes the two electrodes of the ceramics. Ceramics have capacitive properties and are called piezoelectric ceramics.
