Generic products on the market and the special type of instrument can be classified from different angles. Such as by magnetizing current mode split, with DC excitation, AC (other frequencies or frequency) excitation, low frequency square wave excitation and dual-frequency rectangular wave excitation. Several exciting way waveform is shown in Figure 3. Press output signal wiring and excitation (or power) connection standard classification, four-wire and two-wire system. Press converters and sensor assembly methods classified diving electromagnetic flowmeter supplier, there is a separation type and size. 3. electrochemical polarization potential interference. Electrochemical polarization potential interference induced electromotive force is due to differences in bipolar electrode polarity and lead to electrolyte polarization is generated in the electrode surface. Although the use of positive and negative alternating excitation magnetic field can significantly weaken the polarization potential of magnitude, but can not completely eliminate the fundamental polarization potential interference. Their characteristics in the nature of a fluid medium, the material properties of the electrode, the shape of the electrode dimensions related with slowly varying electromagnetic flow meter diving Main, magnitude and other characteristics not offer diving-type electromagnetic flowmeter, the fluid electrochemical potential interference and Solutions Methods. So choose a suitable electrode material (such as tungsten), to design the best shape of the electrodes is an effective way to reduce the size of the polarization potential; other uses alternating positive and negative poles of the rectangular wave excitation technology with microprocessor synchronous wide pulse sampling technique to use two samples before and after the operation function microprocessor subtracted eliminate traffic signal potential of the polarization potential interference. Diving-type electromagnetic flowmeter offer, Chongqing diving electromagnetic flowmeter, Shanghai Automation Instrumentation force measured by the force measuring Shanghai Automation Instrumentation Co., Shanghai Automation Instrumentation Co., force measurement (www.licesh.com) strong, credible, in Shanghai Zhabei District, flow meters and other industries has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the force measured since the instrument into the brilliant and you work for a better future!
