Offset error

Offset error in pressure measurement refers to the difference between the actual zero pressure point and the sensor’s measured zero pressure. It occurs when a pressure sensor or gauge does not read zero when no pressure is applied, which can lead to inaccuracies in all subsequent pressure readings. Offset error is typically caused by manufacturing imperfections, environmental changes (such as temperature), or long-term sensor drift. It is a type of systematic error that must be corrected to ensure accurate pressure measurements. Correcting offset errors is crucial for applications that require high-precision readings.
