Mechanical or electronic sensors integrated into the filters or retrofitted react to continuous changes in the pressure conditions, which depend on the degree of contamination, and signal these via pressure gauges or optical and optical-electrical switches, depending on the design. In the case of suction filters,the negative pressure is registered, in the case of pressure filters the differential pressure and in the case of return-line filters the dynamic pressure. You can determine the optimum time for changing the filter elements without any risk.
