Maintenance Indicators
Industrial Filters · Accumulators
Pressure indicatorsThese types of indicators are used with return lineand suction filters.
They indicate the need for filter element service.
Type P... indicators and pressure gauges M... They are used for indication of pressure and vacuumin filters and can be used for all non aggressivefluids. Due to the filter element contamination the pressuredrop across the filter is increasing. If the staticpressure (resp. the low pressure in suction filters) has reached the allowable value, the filter elementhas to be changed or cleaned.
Pressures switch H... and vacuum meter I...If the adjusted static pressure (resp. the low pres-sure in suction filters) is reached, an electricalcontact is released, used to indicate visual andacoustic signals for the need of filter element service.
Differential pressure indicatorsThese visual and/or electrical indicators are used to monitor the filter elements contamination status by indicating the differential pressure(pressure drop across the filter).
Indicator type E…, A…, F..., R…., S…, G…, T... and U...When the filter element contamination increases or a selected differential pressure is reached, the pistonwith its switching magnet is pushed against a pres-sure spring.An emerging red pin indicates the filter element ser-vice.The visual/electrical version has an additionalmagnetic switch releasing a switching process.If the pressure drop decreases a reset is causedautomatically.
Contamination indicator type V...The visual indicator type V... is equipped with a three colour disc indicating a green field when aclean filter element is installed.If the pressure drop increases, the disc is moved to a yellow and lastly to a red field indicating the need for filter element service.
