Pressure calibration is the process of verifying and adjusting the accuracy of pressure measurement devices, like pressure gauges, transmitters, and sensors. This ensures that these instruments provide accurate readings, which is critical in industries like oil and gas, pharmaceuticals, aerospace, and manufacturing. Proper calibration helps maintain safety, ensure product quality, and improve overall system performance. Here are the essentials of pressure calibration: 1. Understanding Pressure Calibration Pressure calibration is performed by comparing the readings from a device under test (DUT) with a reference standard of known accuracy. Calibration corrects for any deviations between the instrument’s measurements and the actual pressure, bringing the device within acceptable accuracy limits. Calibrations are typically performed at intervals, as part of routine maintenance, or whenever accuracy concerns arise. 2. Types of Pressure Gauge Pressure : Measures pressure relative to ambien...
