1. When the ultrasonic vibrator is damp, you can use a megohmmeter to check the plug connected to the transducer. Check the insulation resistance value to determine the basic situation. Generally, the insulation resistance is required to be greater than 5 megohms. If the insulation resistance value is not reached, the transducer is usually damp. You can put the transducer as a whole (excluding the plastic-sprayed shell) into an oven and set it at 100°C for 3 hours or use a hair dryer to remove moisture to the resistance value. So far.　　

2. The transducer vibrator is ignited and the ceramic material is broken. It can be checked with the naked eye and a megohmmeter. Generally, as an emergency measure, individual damaged vibrators can be disconnected without affecting the normal use of other vibrators.　　

3. The vibrator is degummed. Our transducer adopts the double guarantee process of cementing and screw fastening, which will happen under normal circumstances.

4. The stainless steel vibrating surface is perforated. Generally, the vibrating surface may be perforated when the transducer is used for 10 years at full load.

Ultrasonic transducer

Ultrasonic transducer, including (1) shell, (2) matching layer or acoustic window, (3) piezoelectric ceramic disc transducer, (4) backing, (5) lead-out cable, characterized in that it also includes Cymbal array receiver, which consists of (6) lead-out cable, (7) 8-16 Cymbal transducers, (8) metal ring, (9) rubber gasket. The Cymbal array receiver is located on the disc piezoelectric transducer 3. The piezoelectric ceramic disc transducer is used as a basic ultrasonic transducer, which transmits and receives ultrasonic signals. The Cymbal array receiver is located on the disc piezoelectric transducer, as an ultrasonic receiver, used to receive Doppler echo signals outside the frequency band of the disc transducer.
