Crucial for Microfluidic Applications
Our dead volume is only 74 uL. Microfluidic chips often have volumes of only a few microlitres in total. If pressure sensors interfaced with the chips have volumes thousands of times higher, it becomes challenging to monitor processes in the channels accurately. Purging or filling large dead volumes can take hours through a tiny channel. Our dead volume is over 10 times less than typical NPT style sensors.
Small Changes at Low and High Pressure
Resonant pressure sensors provide the highest resolution available. It is now possible to observe 0.1psi pressure changes at 10,000psi with high clarity. For this test, a RUSKA 7215i pressure controller with a maximum pressure range of 15psi was used. This tool has 0.005% of reading precision and can create accurate small pressure changes. The Omega (PX51-USBH 5,000psi full scale) and DJ Instruments (DFI-SS-01-7.5k-5V 7,500psi full scale) sensors did not respond to the small changes but The XtalX LUQS1 showed these changes clearly even with a full-scale range of 10,000psi.
Ultra Precision Calibration — NIST Tracable Calibration
We use the best-automated equipment for our calibrations. We have a suite of Ruska and Paroscientific secondary standards for our automated 400 point calibrations and regularly compare against our Ruska Primary Standard Dead Weight.
Low Drift
Holding a pressure at 5,000psi over a period of four days, the XtalX doesn't move at all while the Omega gauges drift down by several psi. The DJ Instruments sensor moves up and down by a few PSI.
