2. What does electromagnetic flowmeter AML mean?
AML stands for "Electromagnetic Flow Meter" in English. It is an instrument used to measure the flow velocity of conductive liquids, utilizing the principle of Faradays law of electromagnetic induction. Electromagnetic flowmeter determines the flow velocity of a fluid by measuring the conductivity of the liquid and the applied magnetic field. This type of flowmeter is commonly used in industrial and municipal fields, suitable for flow measurement of various liquid media.
3. EMI measurement mode
EMI measurement mode: EMI (Electromagnetic Interference) stands for electromagnetic interference, often referring to the electromagnetic interference generated by electronic devices to the outside world.
. The EMI measurement mode is mainly used to evaluate whether the electromagnetic radiation generated by electronic devices during operation will cause interference to the surrounding environment or other electronic devices. The following are the detailed steps and key points of EMI measurement mode:1. Measurement preparation equipment selection: Spectrum analyzer: used to display and analyze the frequency and amplitude of electromagnetic signals. Near field probe: specifically designed for close range measurement of electromagnetic fields, capable of locating interference sources. Choose a magnetic field probe or an electric field probe according to the measurement requirements. Measurement environment: Ensure that there are no other electromagnetic interference sources in the measurement environment to avoid affecting the measurement results. The measurement should be carried out under interference conditions such as no wind and no vibration.
2. Measurement steps: Set up the spectrometer: Open the spectrometer, click the [Mode] button, and select the EMI measurement mode.
. Select the scanning mode, usually choosing the comprehensive mode that includes scanning, searching, and measuring. Set the frequency range for measurement, such as 30MHz to 300MHz. Set the resolution bandwidth to 120KHz by default. Set the scale mode of the X-axis to logarithmic format by default. Calibration of near-field probe: In spectrum mode, rotate the near-field probe to find the probe angle corresponding to the maximum signal amplitude. Place the near-field probe at the position of the electromagnetic field to be measured. Scan: Click the 【 Start 】 button to perform a preliminary scan. If the signal is submerged by background noise, the attenuation inside the spectrometer can be turned off to make the distinction between the signal and the background noise more distinct. Open the preamplifier to further amplify the signal image and display more details. Analysis of measurement results: Observe the signal image displayed on the spectrometer and mark the
