low cost pressure switch indicator

1. prevent the oil pipe line being plugged.
2. ensure the hydraulic system safe running

The differential pressure transmitter is mainly used for pipe line filter. When the hydraulic system working, the filter will be gradually plugged for intercepting pollutants, the pressure occurred at the oil in-let and the outlet will be differed (i.e. filter pressure loss). When the pressure difference increased to the set value of the transmitter, the transmitter automatically signal, indicating the operator to clean or replace the filter, to ensure the system’s safe running.
