ABSTRACT:
A pressure and temperature system for monitoring pressure and temperature conditions in a permanent installation in a high temperature production well traversing earth formations where the system in a pressure tool incorporates a programmable logic array device and a low density memory device. Each of a number of independent pressure tools is programmed to respond to a distinct digital polling signal for selecting a particular tool so that a single wire conductor can be used for data and control signal communication between the pressure tools placed downhole and a computer system situated at the earth surface. The system in a tool is powered up and down for each selected operation to conserve individual component useful life and the number of downhole components subject to high temperature is minimized.
