Ultrasonic intensity (sound power) in a liquid acoustic field is one of the most critical parameters for an ultrasonic system. It directly influences the cleaning performance of ultrasonic cleaners and the operational efficiency of ultrasonic sonochemical equipment. Our instruments provide accurate and repeatable measurements of energy distribution and frequency during ultrasonic cleaning tank and ultrasonic sonochemical equipment processes.
The sound intensity meter utilizes the piezoelectric effect, which is the positive piezoelectric property of piezoelectric ceramics. When a force is applied to the piezoelectric ceramic, it converts that force into an electrical signal. Under the same conditions, the stronger the force, the higher the voltage. If the magnitude of the force varies at a certain periodicity, the piezoelectric ceramic will output an alternating voltage signal of the same frequency. Due to cavitation effects and other interferences, the actual voltage waveform is a superposition of a main wave and many secondary waves. The precision ultrasonic frequency (power density) analyzer produced by our company can visually observe the actual waveform and read the sound intensity value.
Performance Advantages
① Simple operation: Insert into the cleaning tank for immediate readings, enabling one-button automatic measurement and automatic data display.
② Handheld lithium-ion battery charging with low standby power consumption; automatically shuts off after ten minutes without signal input.
③ 3.2-inch color screen displays sound intensity/frequency values and real-time statistics of sound intensity.
④ Customizable PC/PLC interfaces available upon customer request for remote data collection.
⑤ Multiple data processing ensures stable data acquisition.
⑥ Multi-level amplification with automatic range switching.
⑦ Probe dimensions can be customized according to customer requirements.
Main Applications
1. Horizontal Comparison: Cleaning machine manufacturers measure sound intensity values at different locations within the cleaning tank to assess the distribution of cavitation intensity. Theoretically, cavitation intensity should be uniformly distributed within the cleaning tank, with minimal variation between measurement points.
2. Calibration reference: Record sound intensity values under specific cleaning tasks to set equipment parameters (such as cleaning intensity) and ensure process repeatability.
3. Consistency testing: Manufacturers can use the same sound intensity measuring instrument to conduct batch testing on shipped equipment to verify product performance consistency.
