Vacuum Gauge for Air & Nitrogen – How One Customer Fixed Their Process Instability
Vacuum Gauge for Air & Nitrogen – How One Customer Fixed Their Process Instability
The Customer
A thin-film coating manufacturer was struggling with inconsistent coating thickness across batches. Their existing vacuum gauge gave slow, drifting readings, especially in the 0.1–1000 Pa range — right where their process mattered most.
They ran only air and nitrogen through their rough pumping lines, but their gauge was over-engineered for gases they never used, and under-performing where it counted.
The Challenge
Issue Impact
Response time too slow Pressure overshoot caused film non-uniformity
Poor repeatability Each batch required re-calibration
Fragile connector pins Frequent downtime for repairs
No power adapter included Delayed installation while sourcing parts
They needed a dedicated vacuum gauge for air and N₂ that was fast, stable, and ready to install the same day.
The Solution: CX-PRN12
Here‘s how it performed:
Requirement CX-PRN12 Delivered
Fast control response <100 ms — pressure stabilized instantly
Consistent readings ±2% repeatability (0.1–1000 Pa) — no more batch drift
Rugged build SS316L + tungsten + Kovar + glass — survived daily cycling
Easy setup 24V DC adapter included — running in 10 minutes
Standard connection DN16 ISO-KF — fit their existing port perfectly
The Result
After 3 months of production:
Scrap rate reduced by 6%
Zero gauge-related downtime
No calibration drift observed between maintenance intervals
The production manager commented:
"Finally, a
vacuum gauge that matches what we actually use — air and nitrogen. No wasted features, just solid readings every time."
