Q: What does IEPE interface diagnosis refer to?
Answer: The corresponding interface LED indicates the status of the IEPE sensor, such as open circuit, short circuit, or Vbias abnormality.
Q: Does it support common audio sampling rates?
Answer: E2445 has a high-resolution sampling rate that can be set to 44.1Ksps, 96Ksps, 384Ksps, or other sampling rates such as 123.4567Ksps. E2445 uses a temperature compensated clock source.
Q: What is the purpose of the high-resolution sampling rate function?
Answer: Example: High resolution sampling rate allows for obtaining integer signal period data by fine-tuning the sampling rate, providing a windowless way to deal with spectrum leakage without compensating for amplitude attenuation after windowing.
Question: What are the differences between E2445 and other collectors
Answer: E2445 has excellent performance and an open data interface. It differs significantly from other analysis software in terms of data processing, analysis, and storage. Engineers can implement flexible data processing according to their own ideas, and users do not need additional software costs; The data of E2445 can interface with deep neural networks to achieve applications such as life prediction and fault diagnosis.
Q: What are the advantages of high sampling rate and high bandwidth?
Answer: In acoustic vibration applications, high-performance collectors can detect high-frequency components, and the energy of vibration is always converted into heat or transferred and accumulated to low-frequency components.
Q: What is the principle of IEPE interface anomaly detection?
Answer: E2445 can obtain the Vbias voltage of IEPE sensors (usually vibration sensors or measuring microphones). When the average Vbias value is greater than 18Vdc or less than 2VDC, it indicates that the sensor is abnormal and the status is displayed through the corresponding channel indicator light.
