Announcing a Revolutionary way to Measure Differential Pressure

Crystal Engineering (USA) is releasing a significant addition to their nVision Reference Recorder. This most recent (and free) quarterly update enables the Intrinsically Safe, hand-held, field calibrator to graph and record average and differential pressure data.

Now, the nVision can display, record and graph differential pressure to a remarkable accuracy of 0.025% of the differential reading up to 300 psi static, 0.05% up to 3,000 psi static, and 0.1% up to 10,000 psi static pressure. The nVision can also record 500,000 data points from each of its two modular sensors, simultaneously. It takes these measurements as frequently as every 0.1 second, without any change in accuracy between -20°C and 50°C.

The nVision delivers this accuracy while maintaining excellent field capability, and without risking sensor damage. Other differential calibrators sustain damage easily, when an improper connection or operation of valves exposes their single sensor to full static pressure. Because the nVision Reference Recorder uses two independent pressure modules, an operator cannot damage either sensor - providing he has selected the appropriate pressure modules for the anticipated static pressure.

“Our customers needed a reliable, safe, and portable device for differential measurements at high static pressure. The nVision was already recording from two sensors with extraordinary accuracy across a broad range of temperatures and pressures. Measuring the difference between the two was a logical step for us. However, accurate differential pressure measurement with two sensors was only possible because of the arrow-straight linearity inherent in our technology. At no additional cost, this new capability puts tremendous value in the hands of our users.” said Tom Halaczkiewicz, President of Crystal Engineering.
