Black Belt Pro Medical grade Calibration Flow transducer

An external provider performed an incorrect calibration on a medical-grade Black Belt Pro. The dual flow transducer was misadjusted and the programs were modified. The flow test stopped working. The line had been down for approximately a week and a half, with a backlog near 18,000 parts.

Incorrect calibration by third party left the line down for a week and a half

The client manufactured medical components for pacemaker connections — where precision in flow and hermeticity measurement is essential. An external calibration provider misadjusted the dual flow transducer and modified the equipment's programs. The flow test stopped working completely.

// 02 · Solution

Precise diagnosis, calibration correction, and validation in 3 hours

Lübeck identified the root cause and restored the equipment without component replacement — only correction of the parameters the third party had modified.

1

Specialized technical diagnosis

Identification of the flow transducer misadjustment as the root cause. The equipment was physically fine — the problem was parameterization.

2

Calibration parameter correction

Adjustment of the dual flow transducer to its correct values. Restoration of the equipment's original programs.

3

Complete functional validation

Verification of flow measurement under real production conditions. Confirmation that the system meets medical-grade standards.

4

Immediate restoration

Equipment delivered operational in 3 hours. The line resumed production the same day as Lübeck's intervention.

// 03 · Result

3 hours. From line down to normal production. 28 units in transfer.

Total recovery of flow measurement on a medical-grade unit.
Immediate production restart — bottleneck eliminated.
System reliability restored without component replacement.
28 Black Belt Pro units in service transfer process to Lübeck — each with pressure transducer, flow transducer, and electronic regulator.

"The client appreciated the speed and technical level demonstrated. The purchase order for periodic calibrations of their 28 units is currently in process."
