"Traditional correction is like shifting a whole ruler, while our system performs 'localized micro-refinement.' For every calibration point you set, the system automatically creates a smooth transition zone. This algorithm ensures that during the highly sensitive sublimation stage, temperature readings remain silky smooth and stable, completely eliminating control oscillations caused by data step-changes."

This system allows independent calibration at 5 key temperature points. Unlike traditional "global offset," it uses "smooth transition" technology. It ensures precise correction as the temperature approaches a calibration point and fades out smoothly as it moves away, preventing data jumps and ensuring the safety of the freeze-drying process.

—— Precision Engineering for Seamless Thermal Control

1. Technical Background: Why Smooth Compensation?

In ultra-low temperature freeze-drying (lyophilization), sensors often exhibit non-linear deviations at extreme ranges (e.g., below -40C.

• The Flaw of Traditional Methods: Simple "Global Offsets" shift the entire range, potentially ruining accuracy at room temperature while fixing the low end. Standard "Step-wise Corrections" cause abrupt data jumps (jerkiness) when crossing thresholds, which can trigger false alarms or destabilize PID heating controls.
• Our Solution: We utilize a Fuzzy Logic-based Triangular Compensation Algorithm. It acts as a "digital filter," applying surgical-grade micro-adjustments only where needed, ensuring the temperature curve remains silky smooth and physically consistent.

2. Core Methodology: The Triangular Logic

The system allows users to set up to 5 independent calibration points. Each point creates a Triangular Influence Zone:

• Localized Precision: Compensation is only active within a user-defined radius (Smooth Bandwidth), leaving accurate zones untouched.
• Gradual Implementation: As the temperature approaches the calibration point, the correction increases linearly. As it moves away, the correction fades out, ensuring no sudden "jumps" in data.

Scenario:

During a validation run, your reference thermometer reads -40.0C, but the machine probe displays -40.6C. You need to fix this 0.6 degree error specifically around the -40C zone.
