As seen at Sensors Expo 2014, the PX51-USBH pressure sensor relies on a 1-kHz, 24-bit USB core and a heavy-duty bonded film pressure sensor to extend output capability to pressure ranges up to 30,000 psi. The transducer is temperature compensated from 60ºF to 160ºF and operates between -50ºF and 185ºF. It is available in pressure ranges from 750 psi to 30,000 psi. Other features include an accuracy of ±0.25% FS (linearity and hysteresis combined), and span and zero thermal effects are 0.003 and 0.005% FSO/F, respectively. Price for the PX51-USBH starts at $550. A datasheet is available at http://www.omega.com/Pressure/pdf/PX51_PXM51-USBH.pdf
