One of the most important parameters that are monitored in industrial operations is pressure. In factories and power plants, as well as pharmaceutical plants and oil refineries, proper pressure measurement guarantees the efficiency of the processes, equipment safety, and the quality of products. But the accuracy of pressure instruments may slowly decrease with constant use, environmental conditions, and mechanical wear. It is critical to ensure that it is calibrated regularly. An industry standard solution to validating and adjusting pressure-measuring devices, a Pressure Calibrator can assist organisations in keeping their operations reliable and within the boundaries of quality standards.
This guide defines the operation of pressure calibration, the various types of available calibration equipment, the features to consider as a critical item and the industrial uses that have made pressure calibration a critical component of any modern maintenance program.
What is a Pressure Calibrator?
A pressure calibrator is a highly accurate device to produce, measure, and check pressure values to test pressure gauges, transmitters, sensors, switches, and other pressure measuring instruments. It is used to compare the reading of a test instrument to a known reference standard of that instrument to see whether the instrument is functioning within its specified accuracy.
Calibration enhances the reliability of measurements, reduces errors during production and facilitates in adhering to international quality standards like ISO 9001 and ISO/IEC 17025.
Why Pressure Calibration is Important
Temperature, vibration, contamination, and continuous operating loads are susceptible to pressure instruments. These factors would lead to calibration drift with time and false readings.
Routine Pressure Measurement Calibration offers a number of benefits:
- Enhances accuracy and consistency of processes.
- Improves the safety of the workplace and equipment.
- Prevents costly production interruptions.
- Promotes regulatory and quality compliance.
- Increases the life of pressure instruments.
- Lowers the cost of maintenance by early fault detection.
Calibration of instruments helps in keeping the important industrial processes going safely and effectively.
Types of Pressure Calibration Equipment
The choice of Pressure Calibration Equipment to use is determined by the application, accuracy required and the range of working pressure.
Digital Pressure Calibrator
One of the most common calibration instruments is a Digital Pressure Calibrator since it is both precise and convenient to use. It includes a digital screen, automatic measurements, and high-resolution sensors used to check the pressure accuracy.
Common features include:
- Multi-unit pressure measurement
- Automatic zero adjustment
- Data logging capability
- USB and wireless connectivity
- Calibration report generation
These are the best tools to use in the field, laboratories and production plants.
Hydraulic Pressure Calibrators
Hydraulic calibrators take oil as the pressure media and they are meant to be applied in high pressure situations. They are very stable and are widely applicable in heavy industries and calibration laboratories.
Pneumatic Pressure Calibrators
Pneumatic systems create pressure with either air or gas, so they can be used in applications that need low pressure where cleanliness and accuracy are a concern.
Pressure Gauge Calibration Process
Pressure Gauge Calibration is the comparison of a pressure gauge with a certified reference instrument under controlled pressure conditions.
An average calibration procedure consists of:
- Checking the instrument to see if it has been damaged.
- Connecting it to the calibration system.
- Providing pressure at various points of the test.
- Comparison of readings with the standard of reference.
- Recording measurement deviations.
- When needed, fine-tuning the instrument.
- Granting a calibration certificate.
After a regular calibration process, the measurement results are precise and traceable.
