Filter – GAUGE
Hydroline filter gauges are precision instruments used to track the health of hydraulic systems by monitoring pressure differentials across filter elements. They act as a real-time warning system to alert operators when a filter is becoming clogged.
- Operating Pressure : High Performance Range
- Application : Industrial & Mobile Systems
About this item
Hydroline filter gauges are critical accessories used to monitor the condition of hydraulic filters by measuring pressure drops or vacuum levels. In hydraulic systems, these gauges typically indicate when a filter element is clogged and needs replacement.
| Category | Key Information & Details |
|---|---|
| Common Models | • GR 40 Visual Indicator: 1/8″ connection size; widely used for standard Hydroline systems. • Pressure Gauge Indicators: Often used on return lines to monitor bypass valve crack pressure. • LG Series (LG2/LG6): Primarily liquid level gauges often paired with filter assemblies. |
| Typical Specs | • Mounting: 1/8″ or 1/4″ NPT/BSP (rear or bottom mount). • Range: 0–10 bar (0–145 PSI) for return lines; vacuum scales for suction lines. • Visual Aids: Green (Clean), Yellow (Caution), and Red (Clogged) color zones. |
| Usage & Maintenance | • Return Filters: Size for max 0.35 bar (5 PSI) pressure drop when clean. • Suction Filters: Size for max 0.03 bar (0.5 PSI) pressure drop when clean. • Replacement: Swap filter elements immediately if the needle stays in the Red Zone at operating temperature. |
