and Information

Calibration can be defined as a process where a comparison is made between (2) two entities; One whose value must be measured and the other entity, known as the standard, which is used as the reference in the comparison.  This process includes the adjustment of any instrument to bring it into alignment with the standard.

Electronic equipment calibration involves the scientific comparison of two instruments.  One instrument should have a known, or proven, correctness so that the other may achieve the same quality.  The biggest electronic calibration objective is to achieve accuracy and precision.  The correctness in turn guarantees efficiency of measurements in healthcare centers, laboratories, and other FDA industries.  The proper diagnosis and treatment of patients is assured while prescription of drugs in in order.

Pressure sensor calibration is a critical activity for many aspects of medical and pharma manufacturing, especially in a cleanroom.  Since these areas are used in the manufacture of drugs as well as medical devices, containers, and enclosures, it is important to ensure that they remain sterile and pressurized as per regulatory guidelines.

Regulatory Guidelines for Pressure Sensor Calibration

Equipment calibration is an integral part of quality assurance for companies producing drugs, medical devices and other products that have an impact on consumer health and safety.  According to the FDA, strict cGMP practices need to be met throughout processing for sterile medical products manufactured with aseptic processing.  Based on the kind of product being manufactured, air cleanliness in cleanrooms and other controlled environments is classified in various ways.

You are aware that you must calibrate your instruments regularly, but how often do you have to calibrate them?  Regular calibration of instruments is necessary as the accuracy of their measurements start to drop over time.  You must make sure the instruments do not get out of calibration.  You will observe that the accuracy of major components of instruments like voltage references, current shunts and input dividers will start to shift over time.  If you maintain a good calibration schedule, this shift is minor and wouldn’t affect the measurements.
