Pressure calibrators are portable devices designed to accurately measure and adjust the pressure of various systems and instruments. They ensure the pressure-sensitive equipment and processes function correctly and safely and help prevent accidents and costly errors. A pressure calibrator can calibrate a broad range of pressure-measuring devices and accurately measure gauge and differential pressure.
It is worth mentioning that the pressure calibrator should be more accurate than the measured devices, up to four times at least, to ensure robust calibration. Regular calibration helps maintain the quality and integrity of pressure-related processes in multiple industries such as manufacturing, aerospace, automotive, pharmaceuticals, and oil and gas. Enrgtech stocks advanced pressure calibrators from leading manufacturers and includes various ranges of Fluke pressure calibrators and Druck pressure calibrators.
Fundamental Purposes of Pressure Calibration
Pressure calibrators serve several important purposes, including:
- Ensuring the accuracy and reliability of pressure measuring instruments.
- Certifying that pressure-sensitive devices meet regulatory and quality standards.
- Calibrating and testing pressure gauges, transmitters, sensors, and other pressure-related equipment.
- Troubleshooting and diagnosing issues in pressure systems.
- Validating the performance of pressure control systems.
Key Features and Components of Pressure Calibrators
Pressure calibrators typically have the following features and components:
- Pressure Source – This component generates the reference pressure for calibration.
- Pressure Measurement Device – It measures the generated pressure accurately.
- Digital Display – Provides real-time pressure readings.
- Control Interface – Allows users to adjust and control the pressure source.
- Data Logging and Storage – Some modern calibrators can log and store calibration data for documentation and analysis.
- Built-in Sensors – For measuring temperature and other environmental factors affecting pressure readings.
- Portability – Pressure calibrators can be portable or benchtop units, depending on the application.
Most Popular Types of Pressure Calibrators
Various pressure calibrators are available, each designed for specific applications. The most common types include:
