Clogging Indicators
The Stauff Spin-On Filter Clogging Indicators are essential components for monitoring fluid contamination in hydraulic systems. The range offers precise solutions for both return and suction line applications, ensuring maximum operational efficiency. Available in visual versions with color-coded segments for immediate pressure or vacuum reading, and in electrical variants with multiple connector configurations (M12, AMP, Deutsch). Manufactured with brass moving parts, they ensure compatibility, accuracy, and long service life.
The Stauff contamination control accessory range includes clogging indicators specifically designed for installation on Spin-On filters. These devices are essential for detecting the saturation status of the filter element, enabling timely maintenance actions and preventing damage to hydraulic components. The robust construction features brass for the movement and pressure element, ensuring reliability and durability.
For return line applications, visual pressure indicators (pressure gauges) are available with graduated scales in bar or PSI. These instruments feature colored segments (Green, Yellow, Red) that clearly indicate operating status:
For suction line applications, Stauff offers visual vacuum indicators (vacuum gauges) with scales in cm Hg or in Hg, also featuring colored zones to simplify reading of critical vacuum levels (up to -76 cm Hg or -30 in Hg).
Electrical indicators provide a remote signal for automated monitoring. They can be configured with different connector types to suit existing system standards:
The flexibility of the range is reflected in the available thread options, offered in both 1/8 BSP and 1/8 NPT. Electrical versions support different operating voltages, including 42 V models (NO or NC contacts) and versions capable of operating between 110 V and 230 V (available for Type W connectors). Pressure set points are calibrated to meet specific requirements, such as 1.3 bar for pressure and -0.1 bar for vacuum, ensuring precise indicator activation.
