The HCT Hydrophone
The HCT hydrophone with MCT-1020 RMS voltmeter is a trustworthy instrument to characterize and monitor the relative acoustic properties of ultrasonic cleaning systems. Its unique single point sensing design allows localized measurements to generate true 3-dimensional acoustic maps of the cleaning tank.
For many ultrasonic cleaning processes, achieving a uniform acoustic field is challenging. This is because there is a broad range of process variables that affect the acoustic field distribution including transducer-to-transducer variation, gas concentration, temperature gradients, flow rate, among others. Ultimately, this contributes to how well particles are removed directly affecting process yield.
The HCT hydrophone is a unique single-point hydrophone that enables true 3-dimensional acoustic mapping for ultrasonic and megasonic cleaning systems. It is coupled with an handheld acoustic meter (MCT) to easily determine the pressure uniformity within a cleaning system. The requirements of the HCT was shaped by semiconductor and data storage suppliers, who demanded a trustworthy measurement instrument to optimize their cleaning process and ultimately improve their particle removal efficiency.
