What is Pressure Calibration?

Pressure Calibration is the process of comparing the output of a device used to measure and display pressure, with that of another pressure measurement device or pressure measurement standard.

Our testing and calibration readings utilize electronic pressure modules with capacities from a vacuum of -15 PSI to 40,000 PSI. We select the right pressure module depending on the measurement range of the device under test (DUT).

Before we begin the calibration process, we exercise the instrument to its full capacity a minimum of three times.

Pressure Calibration

A standard with a known and certified value or capacity is used to compare the DUT during the pressure calibration process. In general, the equipment undergoes a 5-point pressure calibration, with the inspection occurring at every 20 percent of capacity. However, for a higher accuracy pressure transducer or pressure gauge calibration, the review is done at every 10 percent of capacity.

Performing regular pressure calibration to the pressure measuring instruments helps ensure their accuracy and precision.

Why is Pressure Calibration Important?

Pressure gauges are some of the most widely used instruments in manufacturing. The readings from pressure instruments can signal potential issues at different points during the manufacturing process. Therefore, plant workers rely on these readings to optimize their operations.

Inaccurate readings can be detrimental to the organization and cause delays, injury, inferior quality products, and costly product recalls.

Benefits of Routine Pressure Calibration

Routinely calibrating your pressure measurement instruments can significantly benefit your organization. Although there are many benefits to having calibrated equipment, these are four of the main benefits you can expect:

  • Maintain Safety in Process Environments: Calibrating pressure transmitters is extremely important, as incorrect pressure readings could potentially endanger the lives of workers, and the general public.
  • Maintain Productivity Levels: The performance of pressure transmitters could be affected by various reasons, including operational stress and environmental issues. In most instances, the errors may go unnoticed until a serious problem develops. Calibration reduces drift in readings, which lowers the risk of a potentially devastating impact on productivity.
  • Avoid Downtime: Machine downtime can curtail revenue and lead to wasted resources. Companies who are proactive in calibrating their instruments can significantly lower their downtime and maximize their productivity.
  • Remain Compliant: Manufacturing companies are subject to state, federal, and international regulations to which they must adhere to remain in business. Pressure instrument calibration is essential to meeting ISO and other certification standards.
