Burn in Hours That Remove the Steepest Early Drift
Thermal burn-in under active electrical bias removes early non-linear drift, locking in long-term calibration stability before sensors reach the field.
Ceramic Pressure Sensor Conditioning
Stability Treatment
Pre-conditioning process applied to pressure transducers to ensure consistent performance over their service life. Manufacturers use ceramic pressure sensor conditioning to relieve the internal stresses that develop during the firing and assembly of the sensor body. This step reduces the likelihood of signal drift after the device is installed in the field.
Stress Relief
High temperature soaking and pressure cycling are the primary methods used in this procedure. The ceramic pressure sensor conditioning routine forces the material into its final equilibrium state. Without this treatment, the ceramic diaphragm might undergo subtle structural changes during its first few weeks of operation.
Temperature Cycle
Rapid changes between extreme cold and heat test the integrity of the bond between the sensing element and the ceramic substrate. During ceramic pressure sensor conditioning, the device is subjected to temperatures that exceed the standard operating range. This exposure identifies weak units that might fail prematurely due to thermal fatigue.
Drift Reduction
Long-term accuracy depends on the ability of the sensor to return to its zero point after a pressure event. A thorough ceramic pressure sensor conditioning process ensures that the hysteresis remains within the specified tolerance. Metrology labs verify the effectiveness of the conditioning by monitoring the output of a sample group over several days.
This rigorous approach guarantees that the sensors provide reliable data for critical industrial applications.
