Pressure Calibration

Experts in low and ultra-low pressure calibration across a range of device types

Accuracy

The accurate calibration of pressure sensing devices is absolutely crucial for safety, reliability, and operational efficiency across numerous industries. In settings like chemical processing plants, aerospace applications, or medical devices, even minor pressure measurement inaccuracies can lead to catastrophic failures, compromised product quality, or risk to human life.

Proper calibration ensures that pressure vessels operate within their designed parameters, manufacturing processes maintain consistent quality, and critical safety systems respond appropriately to dangerous conditions.

      Furness Controls Pressure Traceability Chain

      Every calibration we issue traces back, in a fully documented and unbroken chain, to the fundamental SI units of mass, temperature and electrical measurement.

      At the top of that chain, pressure is realized in two independent ways. Piston gauges and dead weight testers generate a known pressure directly from a calibrated mass acting on a precision piston of known area — the same principle behind P = force ÷ area, with the piston's temperature continuously monitored to correct for thermal expansion. In parallel, our digital pressure references and FC0560 reference standard generate pressure electronically, via transducers whose accuracy depends on precise resistance and voltage measurements. Running both methods side by side means each one acts as an independent check on the other — agreement between them is strong evidence the whole chain is sound.

      These primary standards are used sparingly, to protect their accuracy. Instead, they're used to calibrate our working standards, which handle day-to-day calibration work. Those working standards, in turn, calibrate the instruments we take out for on-site calibrations, and ultimately the devices we supply and service for customers.

      The result is a hierarchy where every instrument is only ever calibrated against something more accurate than itself, all the way back to the underlying physical realization of pressure. That's what gives a Furness Controls calibration certificate its credibility: it isn't just a reading, it's the end of a fully traceable chain, so you can be confident your instrument's accuracy is genuinely underwritten by national and international measurement standards.
