How PACE Tallis Can Be Your Trusted Transfer Standard

In pressure calibration, accuracy is everything—but efficiency and equipment longevity matter too. Digital Piston Gauges (DPGs) and Deadweight Testers (DWTs) are often relied upon as reference standards, but using them as transfer standards can lead to overuse, wear, and operational inefficiencies. 

That’s where PACE Tallis comes in.

The Hidden Cost of Overusing Your Primary Standards

DPGs and DWTs are precision instruments, but they’re not designed for constant use in day-to-day calibration tasks:

• DPGs are sensitive to mechanical shock, contamination, and sensor drift. Frequent handling and exposure can degrade their performance and shorten their service life.
• DWTs, while highly accurate, are manual, slow to operate, and not ideal for achieving or maintaining the fine control required at PACE Tallis accuracies. They require careful setup, levelling, and environmental control, making them impractical for routine or high-volume calibration work.

Using these instruments for every calibration task is technically possible, but impractical, inefficient, and likely to cause unnecessary wear. 

Your DPGs and DWTs should be preserved for critical reference checks, not routine calibration work.

PACE Tallis: The Smarter Transfer Standard

PACE Tallis is a high-accuracy pressure indicator designed to take the strain off your primary standards. 

It offers:

• High-resolution measurement traceable to national standards
• Lowest possible uncertainties from a digital standard
• Fast response times for efficient calibration workflows
• Automated calibration routines to reduce human error
• Compact, portable rugged design suitable for both lab and field environments

By using PACE Tallis as your transfer standard, you can reserve your DPGs and DWTs for periodic verification and reference checks—preserving their accuracy and extending their lifespan.

Why DWTs Struggle at Tallis-Level Accuracy

Deadweight Testers are fundamentally (auto-loaders aside) manual devices. Achieving the fine pressure measurements required to match the resolution and repeatability of PACE Tallis is difficult and time-consuming. Even small adjustments require physical manipulation of weights and pistons, and environmental factors like temperature and vibration can introduce errors. 

In contrast, PACE Tallis delivers precise, repeatable pressure measurement at the push of a button.

A Smarter Calibration Strategy

Consider a calibration setup where PACE Tallis handles routine pressure measurement. Your DPG is used only to verify Tallis performance at scheduled intervals, and your DWT is reserved for annual traceability checks. 

This approach:

• Reduces wear and tear on expensive reference instruments
• Speeds up calibration processes
• Improves repeatability and consistency
• Lowers long-term maintenance and recalibration costs

Conclusion: Let Tallis Carry the Load

Calibration excellence isn’t just about accuracy—it’s about sustainability, efficiency, and smart resource management. 

By using PACE Tallis as your transfer standard, you can take the weight off your DWT, give your DPG a well-earned break, and build a more resilient calibration process.
