Can a barrier solve the problem of interference?
Thread Content
In our factory, the vibration of the booster pump returns to 3500 after passing through a pre-amplifier, and then is displayed on the DCS system; this causes severe interference. Adding an MTL5031 helped, but it did not resolve the issue completely. Can the isolation barrier not completely eliminate interference, or are there other issues?
Safety barrier: It limits the energy entering the area, by controlling voltage and current, so that no sparks are generated in the wiring there under any circumstances, thereby preventing explosions. This type of explosion prevention method is known as intrinsically safe. Isolation barrier: It can prevent ground loop currents from interfering with signals, while also protecting the system from hazardous energies present in the field. For example, if a large current flows into the circuit on-site, it will damage the isolation barrier without affecting the IOs. The method mentioned by the original poster should be able to solve the problem.
