Our Process for Pressure Calibration Services
What is Pressure Calibration?
Pressure calibration is the process of comparing the output of a device used to measure and display pressure against a certified pressure measurement standard with known accuracy. This ensures your instruments provide reliable, accurate readings that meet regulatory requirements and support quality decision-making.
Our Calibration Methodology
Our testing and calibration process utilizes electronic pressure modules with capacities ranging from vacuum conditions of -15 PSI to high-pressure applications up to 40,000 PSI. We select the appropriate pressure module based on the measurement range of your device under test (DUT).
Before beginning calibration, we exercise each instrument to its full capacity a minimum of three times to ensure stable performance. Your equipment then undergoes a comprehensive 5-point pressure calibration, with inspection occurring at every 20 percent of capacity. For higher accuracy pressure transducers and gauges requiring greater precision, we perform calibration at every 10 percent of capacity, achieving accuracy specifications from 2% down to 0.1% or better.
Benefits of Professional Pressure Calibration
- Maintain Safety in Process Environments – Accurate pressure readings protect workers and the public from dangerous conditions caused by incorrect pressure measurements
- Preserve Productivity Levels – Regular calibration reduces instrument drift and prevents unnoticed errors that could devastate production efficiency
- Avoid Costly Downtime – Proactive calibration significantly reduces unexpected equipment failures and maximizes operational uptime
- Ensure Regulatory Compliance – Proper pressure calibration is essential for meeting specific certification standards required in regulated industries
Risks of Neglecting Pressure Calibration
Inaccurate pressure readings can lead to product quality issues, safety hazards, regulatory violations, costly product recalls, and production delays. In manufacturing environments where plant workers rely on pressure measurements to optimize operations, uncalibrated instruments create significant operational and financial risks.
