What should I do after the intelligent electromagnetic flowmeter is interfered by the digital display temperature controller?

according to the characteristics of general intelligent electromagnetic flowmeter system software, the key ningbo digital thermostat manufacturer discusses the dry deflection origin of electromagnetic flowmeter from the aspect of hardware equipment upgrading, for example, Zhejiang digital thermostat manufacturer electromagnetic induction coupling and tip discharge are intelligent electromagnetic flow meter. In the electromagnetic induction total flow transmission, because the The outgoing line is in an alternating electromagnetic field. When the transmission is plugged in, it is caused in the closing control loop of the outgoing line. Induced electromotive force. This type of electromagnetic interference, when superimposed on precise measurement signals, compromises the operation of the system. Various excitation regulator methods can give rise to different interference signal issues. The DC excitation regulator method is easy to cause electric polarization dry deflection, and the communication AC excitation regulator method is easy to cause orthogonal and dry deflection (90 degree dry deflection), and coherent deflection (I. e. DC dry deflection), etc. Orthogonal interference refers to interference that is 90 degrees out of phase with the total traffic data signal. When the intelligent electromagnetic induction flow transmitter adopts the communication AC excitation regulator method, it will cause an alternating electromagnetic field, while the closing control loop formed by the metal electrode, the lead wire, the measured substance and the input power circuit of the converter is in the dry and alternating electromagnetic field, and the closing control loop is unlikely to be completely parallel to the magnetic induction line caused by the alternating electromagnetic field of the intelligent transmitter, there will be a part of alternating magnetic induction lines crossing the closed control loop, thus causing a dry deflection electromotive force in the control loop. In the electromagnetic flowmeter, the intelligent transmitter and the converter are highly valued to remove or suppress the 90 ° dry deflection.

intelligent electromagnetic flowmeter with coherent deflection direct current dry or common mode interference refers to electromagnetic interference that appears on two metal electrodes of intelligent transmitter at the same moment and has the same amplitude and position. When the total flow rate is zero, that is, when the measured liquid is not moving in place, the same belief number measured means in-phase electromagnetic interference. Electromagnetic flowmeters employ a variety of methods to suppress common-mode interference. At the level of intelligent transmitter, the metal electrode and the magnetic ring of the excitation regulator are balanced and symmetrical in terms of geometric shape, specifications and technical parameters, and each is strictly shielded to reduce the contact resistance hazard between the metal electrode and the magnetic ring of the excitation regulator.
