Introduction
Accurate pressure measurement plays a critical role in industrial safety, product quality, and process efficiency. From manufacturing plants and laboratories to oil & gas facilities, pressure gauges must deliver reliable readings at all times. To ensure this accuracy, regular calibration using the right pressure calibrator is essential.
Choosing the wrong calibrator can lead to measurement errors, compliance issues, and unnecessary downtime. This guide from AIDI SALAM will help you understand the different types of pressure calibrators and how to select the most suitable solution for your application.
What Is a Pressure Calibrator?
A pressure calibrator is a precision instrument used to test, adjust, and verify the accuracy of pressure gauges, sensors, and transmitters. By generating or measuring known pressure values, the calibrator allows technicians to compare actual readings against reference standards and correct any deviation.
Pressure calibrators are widely used in:
Industrial maintenance
Calibration laboratories
Quality assurance departments
Process control systems
Common Types of Pressure Calibrators
1. Deadweight Pressure Testers
Deadweight testers are considered one of the most accurate methods for pressure calibration. They operate based on fundamental physical principles, using calibrated weights and piston-cylinder assemblies to generate precise pressure.
Best suited for:
High-accuracy reference standards
Applications requiring traceability
Key advantage: Exceptional accuracy and long-term stability
Limitation: Less portable and more time-consuming to operate
2. Dedicated Pressure Calibrators
Dedicated pressure calibrators are electronic instruments designed specifically for pressure calibration tasks. They typically include built-in pressure sensors, data logging, and advanced calibration functions.
Best suited for:
High-volume calibration environments
Industrial and laboratory use
Key advantage: High accuracy with digital convenience
Limitation: Usually focused on pressure only
3. Handheld Pressure Calibrators
Handheld pressure calibrators combine portability with functionality. Many models integrate pressure measurement with electrical signal calibration (such as 4–20 mA), making them ideal for field technicians.
Best suited for:
On-site and field calibration
Maintenance and troubleshooting tasks
Key advantage: Compact, versatile, and efficient
Limitation: Accuracy may be slightly lower than lab-grade instruments
Key Factors to Consider When Choosing a Pressure Calibrator
Pressure Range
Always select a calibrator that covers the full operating range of your pressure gauges. Using a calibrator too close to its maximum limit can reduce accuracy and lifespan.
Accuracy Requirements
Calibration accuracy should exceed the accuracy of the device under test. For critical applications, a calibrator with ±0.05% accuracy or better is recommended.
Application Environment
Consider whether calibration will be performed in a laboratory or in the field. Environmental conditions such as temperature, humidity, and portability requirements play an important role.
Ease of Use and Features
Modern pressure calibrators may include features such as:
Digital displays
Data storage and reporting
Automated calibration routines
These features can significantly improve efficiency and reduce human error.
In-House Calibration vs. Calibration Services
Some organizations prefer to perform pressure calibration internally, while others rely on professional calibration laboratories. In-house calibration offers flexibility and faster turnaround, but requires investment in equipment and expertise.
Using a professional calibration service ensures:
Traceability to international standards
Certified calibration reports
Compliance with ISO and industry regulations
