Druck Pressure Calibrators

A pressure calibrator is a precision instrument designed to verify the accuracy of pressure readings from other pressure-measuring devices. To ensure reliable calibration, the calibrator must be significantly more accurate than the device being tested, typically by a factor of four. These versatile tools are available in both portable handheld models for field use and workshop models for laboratory applications, catering to the diverse needs of process professionals.

Device Compatibility of Pressure Calibrators

Pressure calibrators are designed to work seamlessly with various pressure-measuring devices, ensuring accurate calibration and testing across different applications:

Transmitters

Pressure calibrators can verify the accuracy of pressure transmitters, which convert pressure readings into electrical signals. This is crucial for maintaining the reliability of industrial processes that rely on accurate pressure measurement and control.

Gauges

Whether analog or digital, pressure gauges are essential for monitoring pressure levels in various systems. Pressure calibrators can be used to calibrate these gauges, ensuring that they display accurate pressure readings, which is vital for safety and process optimisation.

Switches

Pressure switches are used to trigger actions based on pressure thresholds. Calibrating these switches with a pressure calibrator ensures that they activate at the correct pressure levels, preventing malfunctions and ensuring the safe operation of equipment. In critical applications, isolator switches may be incorporated to provide additional electrical isolation and safety for both the operator and the equipment.

Features of Pressure Calibrators

Pressure calibrators are equipped with a diverse range of features, accuracies, and pressure ranges to meet specific calibration needs. Some models offer intrinsically safe operation, while others include reference data recorders for documenting calibration results.

Key features comonly found in most pressure calibrators include:

• Rugged and reliable construction for field use
• Compact and lightweight design for one-handed operation
• Built-in pumps for easy pressure generation
• Precision regulators for precise pressure control
• mA measurement, loop power, switch test, and transmitter error calculation functions
• Time-saving calibration and testing capabilities

Different Configurations of Pressure Calibrators

Pressure calibrators are available in various configurations to cater to different environments and calibration requirements:

For Field

Portable pressure calibrators are designed for field applications, where portability and multi-functionality are essential. These handheld devices often include features like voltage, amperage, and digital signal monitoring or recording, consolidating multiple instruments into one and reducing recalibration and maintenance costs.

In the Lab

In laboratory settings, where high accuracy and precise pressure control are paramount, precision pressure calibrators with advanced features are often utilised. These instruments offer added features like automated calibration routines, data logging capabilities, wider pressure ranges, and higher accuracy levels to meet the stringent demands of laboratory calibration, while ensuring traceability to primary standards.

For optimal performance and uninterrupted operation, it's crucial to connect these precision instruments to a reliable UPS power supply, safeguarding against potential data loss or calibration errors due to power fluctuations.

What Are Deadweight Testers?

Deadweight testers are high-precision instruments used for pressure calibration in laboratory environments. While they are known for their superior accuracy, they are also bulky and require skilled operators. High-end deadweight testers remain the gold standard for pressure calibration at the highest level, but handheld and electronic pressure controllers are increasingly replacing them in field and process applications.

Pressure Calibrators Applications

Pressure calibrators find applications in various industries and processes where accurate pressure measurement is absolutely critical:

• Calibration of pressure sensors in manufacturing processes.
• Verification of pressure gauges in oil and gas production.
• Testing of pressure switches in hydraulic systems.
• Maintenance of pressure transmitters in power plants.
• Calibration of medical equipment for patient safety.

How to Choose the Right Pressure Calibrator for Your Needs

Selecting the ideal pressure calibrator involves careful consideration of several key factors. Firstly, determine the required accuracy and pressure range to match your specific applications. Secondly, evaluate the features that best suit your needs, such as built-in pumps, data logging capabilities, or intrinsically safe options. Additionally, consider the environment in which the calibrator will be used, opting for a rugged, portable design for field work or a benchtop model for laboratory use.
