Key Features
High-Pressure Resilience: Built to withstand severe pressure surges and cyclic fatigue in heavy-duty machinery.
Vibration & Pulsation Dampening: Liquid-filled design eliminates pointer flutter for stable, highly readable measurements.
Corrosion-Resistant Media Contact: Premium wetted parts compatible with a wide range of synthetic and mineral-based hydraulic oils.
Rapid Diagnostics: Provides instant visual feedback to detect line blockages, pump wear, or filter clogs before catastrophic failures occur.
Liquid Filled / Damped Design
Glycerin Filling Standard: Factory-filled with high-purity glycerin to dampen severe mechanical vibrations, water hammer, and pressure oscillations, keeping the pointer rock-steady.
Silicone Oil Alternatives: Available with high-temperature or low-temperature silicone oil fills for extreme operational environments ranging from sub-zero outdoor yards to hot industrial foundries.
Extended Internal Life: Viscous damping fluid continuously lubricates internal movement gears and pivots, virtually eliminating premature wear and tear.
Pressure Equalization Venting: Features an integrated rubber fill plug or pressure relief vent to prevent case over-pressurization caused by internal thermal expansion.
Accuracy & Reliability
Strict Calibration Standards: Every accurate hydraulic pressure gauge is multi-point calibrated using state-of-the-art dead-weight testers to ensure EN 837-1 compliance.
Low Hysteresis Performance: High-grade elastic materials ensure the pointer returns precisely to zero after repeated pressure loading and unloading cycles.
Overpressure Tolerance: Designed to safely withstand temporary overpressure spikes up to 130% of the maximum scale rating without permanent calibration shift.
Long-Term Stability: Resilient internal linkages prevent drift over extended operational lifespans, minimizing the need for frequent field adjustments.
Maintenance
Routine Visual Inspection: Regularly check for external oil leaks, cracked windows, bent pointers, or excessive casing corrosion.
Zero-Point Verification: Periodically inspect the gauge when the system is fully depressurized to ensure the pointer rests squarely at the zero stop pin.
Annual Calibration Cycle: Implement a 12-month recalibration schedule using certified reference standards to maintain quality management compliance.
Replacement Protocol: Immediately replace any gauge exhibiting sluggish pointer movement, internal fluid discoloration, or permanent calibration drift.
