YZS Series Cross Pointer Pressure Gauges
YZS Series Cross Pointer Pressure Gauges feature dual pointers for simultaneous measurement of two pressure parameters (e.g., system pressure and back pressure) in hydraulic/pneumatic systems. Inaccurate dual-pressure monitoring can cause system imbalance and component wear. Our YZS gauges adopt precision dual movements and anti-interference structures, ensuring clear pointer differentiation and stable measurement, suitable for hydraulic power units and industrial transmission systems with accuracy class up to 1.5.
Field Application Case
A heavy machinery manufacturer faced frequent hydraulic cylinder failures due to inaccurate dual-pressure monitoring in their excavator hydraulic systems. After replacing with YZS-102ZT cross pointer pressure gauges (complying with EN 837-1), technicians could accurately monitor working pressure and return pressure simultaneously. This reduced hydraulic component wear by 40% and unplanned maintenance downtime by 30% within 6 months.
