What causes the E+H electromagnetic flowmeter to have a blank screen with no display?
Thread Content
Could everyone help analyze what causes the electromagnetic flowmeter to show a blank screen? During the initial debugging phase, liquid entered the display screen. The circuit board shows signs of rust.
Bro, what’s there to analyze? The display got damaged due to water getting inside it.
:D wants to see which part of the circuit or component is likely to cause damage
It is known that water entered the instrument during the initial debugging phase; therefore, the instrument should be inspected and repaired. It can only be put back into use if its functions and performance are normal. If there are issues, it needs to be repaired or replaced. Why then allow this instrument to be used at the work station? It’s not just the instruments that have water in them; the human brain also needs to be checked.
When a circuit board is contaminated by water, it can cause damage to electrical connections and components, resulting in a blank screen on the electromagnetic flowmeter. If no measures are taken in a timely manner, it may cause severe damage to the circuit board, thereby affecting the proper operation of the electromagnetic flowmeter. Therefore, in response to this situation, it is necessary to immediately inspect the circuit board to determine whether the components have been damaged, and take appropriate measures to ensure that the electromagnetic flowmeter can function properly.
