Instrumentation of the Hewlett-Packard Quartz Pressure Probe
Abstract/Contents
- Abstract
- A few years ago Hewlett-Packard donated a quartz pressure gauge to Stanford University's Department of Petroleum Engineering. The equipment received consisted of a high resolution quartz pressure probe capable of measuring pressure changes of .01 psi from atmospheric to 12,000 psi pressure; and a pressure signal processor designed to supply power to the probe, filter out any extraneous noise in the pressure signal, and amplify the signal. Thus, with the appropriate electronic and mechanical equipment, the probe's signal could be converted into a pressure reading if the temperature were known.Since the pressure signal is a function of temperature, it was decided early on that a temperature probe should be obtained which could be run in conjunction with the pressure probe. This probe would allow temperature measurement within +1?F, thereby resulting in pressure data accuracy within +0.5 psi or +0.025% of the reading. The addition of the temperature probe complicated the electronics and appreciably added to the system cost, but the extra information and accuracy obtained from its employment mandated its acquisition. Operation in a field situation necessitated obtaining a portable wire line unit and electronic equipment capable of monitoring, displaying, and recording pressure and temperature as a function of time. This report deals with the equipment selected and its operation.
