Heavy-Duty Hydraulic System Pressure Gauges
-- Steady & Reliable Manufacturer --
Product Overview
Our heavy-duty hydraulic system pressure gauges are purpose-built to withstand the intense pressure, high-frequency pulsations, and severe vibrations common in hydraulic power units, presses, and mobile machinery. These gauges utilize a precision Bourdon tube, often protected by liquid filling (Glycerin or Silicone), which effectively dampens pointer movement, ensuring accurate and readable measurements even under dynamic operating conditions. They are the benchmark for reliability in the demanding field of fluid power engineering.
Key Features
- Liquid-Filled Case for Dampening and Lubrication.
- Robust, high-strength Bourdon tube system.
- Over-pressure protection up to 1.3× full scale.
