CCD54A-LP sensors come with a calibrated voltage output for pressure measurement of .15 to 3 psi.  Input of 2.7 to 5.5V. 8 pin ceramic dip, differential or gauge models.  Low profile package of less than 9 mm, forward facing ports.

Gage, high pressure, dual-in-line (XFGM) or horizontal pressure port (XFHM), 5V supply, calibrated voltage output

Gage, high pressure, dual-in-line 3 mm or 6 mm pressure port, 5V supply, calibrated voltage output

Today, Fujikura is the pioneer of the zirconium based, current limiting oxygen sensors. This style of sensor has many advantages over other ways of measuring oxygen.
