Abstract
An apparatus that is usable with a subterranean well includes a safety valve assembly and a pressure/temperature sensor. The safety valve assembly is controllable to selectively isolate a formation of a well from the surface of the well. The pressure/temperature sensor is located in the safety valve assembly to measure a pressure/temperature near the safety valve assembly.
