Liquid Filled Gauges, Vent Plug
MODEL L11
Benefits
Repair frindly
Precision measurement
Reduced needle flutter
Enhanced durability
No steaming up in the lens for outdoor
Applications
For air/gas , oil, water or any other medium which does not clog, crystallize or attack copper alloy.
For measuring field of fluid power, vibration and dynamic pressure working, such as hydraulic systems, industrial machinery, various process or automotive.
DESCRIPTION
MODEL L11 use a vent plug for liquid filled gauge help gauge to release pressure, and the needle back to zero. so, it features with robust construction, combining a durable outer casing with a liquid-filled chamber to enhance their performance and longevity.
Reduced needle flutter : Due to the case filling, the pressure element and movement are damped that reduces needle flutter, allowing for more precise and stable pressure readings. So, the gauges can be used for dynamic loads. This is particularly important when monitoring critical systems where accuracy is paramount.
Whether you're monitoring hydraulic systems, ensuring safety in industrial processes, or maintaining optimal pressure conditions, MODEL 11 is your trust-able instrument, offering accuracy, durability, and performance.
