When is Calibration Required? When the sensor or object being calibrated is relied on as the source of truth to de-risking the consequences of the sensor or object not being accurate.
DefineTheBox includes calibration tracking and history as part of the Quality Management System and reduce risk and make it easier to identify trends of instrument drift.
As part of Risk Management on instruments, it is fair to assume the instrument will lie and provide a false reading. Calibration helps book end the lots of products made with quality assurance that the instrumentation used for process was accurate.
Temperature Probes in food manufacturing are calibrated to help assure that Hazard Analysis Critical Control Points are achieved such as Bacteria Kill Steps before packaging.
Pressure Sensors are often calibrated so that the pressure vessels they are monitoring do not exceed safe vessel design and explode causing asset or personnel harm.
Flow Sensors are often calibrated to assure process compliance for product quality and environmental compliance of discharge rates
Calibration Certificates Requires an Asset ID, Part Number of the asset being Calibrated, the parent calibration object’s Serial Number and Part Number, the Unit of Calibration and the Calibration requirements such as set the offset until the value is Plus or Minus, One.
DefineTheBox tracks Calibrations against Serial Numbers which can be assigned to Account Assets
Calibration data is stored under the Quality Management System of your database, often a company starts their database to serve customers. Calibration and Serial Number with Product type gives greater tracking within Customer Relationship Management (CRM)
Many displays of sensors have a variable for calibration offset. This offset is the number used to bring the instrument being calibrated into accuracy. See below an example of calibrating the sensor input to a Proportional, Integral and Derivative controller.
