CLOGGING INDICATORS
24Pages

Clogging Indicators Clogging indicators are devices that check the life time of the filter elements. They measure the pressure drop through the filter element directly connected to the filter housing. These devices trip when the clogging of the filter element causes a pressure drop increasing across the filter element. Filter elements are efficient only if their Dirt Holding Capacity is fully exploited. This is achieved by using filter housings equipped with clogging indicators. The indicator is set to alarm before the element becomes fully clogged. MP Filtri can supply indicators of the following designs: - Vacuum switches and gauges - Pressure switches and gauges - Differential pressure indicators These type of devices can be provided with a visual, electrical or both signals. The electronic differential pressure clogging indicator is also available. It provides both analogical 4-20 mA output and digital warning (75% of clogging) and alarm (clogging) outputs.

Clogging indicators Clogging indicators Suitable indicator types VACUUM INDICATORS Vacuum indicators are used on the Suction line to check the efficiency of the filter element. They measure the pressure downstream of the filter element. Standard items are produced with R 1/4” EN 10226 connection. Available products with R 1/8” EN 10226 to be fitted on MPS series. BAROMETRIC INDICATORS Pressure indicators are used on the Return line to check the efficiency of the filter element. They measure the pressure upstream of the filter element. Standard items are produced with R 1/8” EN 10226...
