One of the most important factors influencing the accuracy of a pressure transmitter is interference. Electromagnetic energy is generated during the operation and use of electronic or electrical equipment, and the interference will be more serious when high-power equipment is turned on or off. At the same time, the effect of interference has a certain hidden characteristic. Therefore, it is particularly important for pressure transmitters to reduce the number of interfering factors. There are basically three types of interference encountered by pressure transmitters. Electric field interference, magnetic field interference, and electromagnetic interference. These disturbances are due to the interaction between the circuit and the electric and magnetic fields. The pressure transmitter has a good signal grounding and is able to suppress interference. Grounding is divided into safety grounding and signal grounding, safety grounding is to protect the safety of electrical equipment and personnel accidentally touched, so that the risk of electric shock will not occur; Signal grounding is to provide an equipotential point for the signal voltage. The safety ground and signal grounding points should not be in the same location, otherwise the signal end will introduce unexpected interference. Therefore, to effectively suppress interference, it is necessary to have a good signal grounding. The signal selection of the pressure transmitter can also have an impact on the interference. The output signals of pressure transmitters are divided into current, voltage, and digital outputs. In the selection of output signals, the current output method is generally used. The pressure transmitter chooses to use this output, which is highly resistant to interference. Increasing the packaging of pressure transmitters is also an effective measure to reduce their failures and interferences. In addition to eliminating and suppressing unnecessary interference from various electromagnetic fields as much as possible, the tightness of the connection between the pressure transmitter itself and the process piping or equipment should not be overlooked. Therefore, the signal ground, current output, and package hermesis can effectively reduce the interference of the pressure transmitter.
