How to Stop Needle Flutter in a Pressure Gauge – Winters' StabiliZR® Solution
Stop Needle Flutter in Pressure Gauges with Winters' StabiliZR® GAUGES
If you're dealing with needle flutter in pressure gauges due to vibration or pulsation, Winters has the answer: the StabiliZR® Series. This innovative technology offers a dry gauge with a dampened movement system that effectively eliminates pointer flutter, without the need for traditional liquid filling.
Why Do Pressure Gauges Flutter?
Needle flutter is typically caused by mechanical vibration or pulsating pressure in the process line. This makes making accurate readings difficult. In traditional liquid-filled gauges, glycerin is used to dampen the movement. However, this comes with issues like leaks, discoloration, compatibility with process media, and temperature limitations.
The StabiliZR® Advantage
Winters’ StabiliZR® gauges solve all of these problems with a dry dampened movement without the hassles of dealing with a liquid-filled gauge.
Key Benefits:
- ✅ Eliminates needle flutter from vibration and pulsation
- ✅ No leaking or fluid compatibility issues
- ✅ Operates at higher temperatures than glycerin-filled gauges
- ✅ Easier to read, even in challenging environments
- ✅ No need for case draining or refilling
- ✅ Lightweight, reinforced design
How It Works:
The StabiliZR® design extends the pointer shaft through the back of the movement, where a small flat paddle is affixed. A stainless steel cap filled with silicone covers the paddle, creating just enough resistance to dampen the movement — simulating the effect of glycerin but with zero mess and maintenance.
