High level switch alarm
Thread Content
The Dinghua level switch gives high-level alarms from time to time. The liquid level is linear and normal, and the gauge display is also normal. The probe of the level switch that triggers these high-level alarms has been cleaned and re-sealed, but the problem persists. I would appreciate any advice from those with more experience
Is it a tuning fork switch or a float switch? If there are spare parts, replace one first; take the one that was removed and study it carefully later.
Under these operating conditions (mainly the gas phase temperature), is there no material (paraffin) attached to the tuning fork?
