The Bollfilter 0550039 Differential Pressure Contact Indicator is a differential pressure contact indicator (also called a differential pressure gauge or pressure switch) for monitoring the contamination of filter elements in Bollfilter filtration systems. It measures the pressure difference between the filter inlet and outlet and provides visual and electrical signals to assess the condition of the filter element.
