Overlooking calibration cycles in high-frequency use scenarios (e.g., daily testing) leads to degraded accuracy over time, but cycle matching solutions ensure probes remain reliable between calibrations.Gas Pressure Scanwelcome to click on the website to learn more!
High-frequency use accelerates drift in critical components like pressure sensors and hole geometry. A production line test found that a generic probe used 10x daily required recalibration every 30 days to maintain <1% error, whereas a probe designed for high-frequency use (with stabilized materials) stayed within tolerance for 90 days.
Material selection impacts calibration frequency. Inconel 718 probes have better dimensional stability than 304 stainless steel in high-use scenarios, with 50% less drift over 1000 tests. A aerospace testing facility reduced calibration costs by 60% by switching to Inconel probes for daily engine tests.
Design features like self-compensating sensors (which adjust for temperature-induced drift) extend calibration intervals. In a continuous wind tunnel test, probes with self-compensating sensors maintained accuracy for 120 days, compared to 60 days for standard sensors.
Cycle matching steps include: 1) estimating daily/weekly usage frequency; 2) selecting probes with calibration intervals ≥1.5x the usage cycle
