Abstract: Quartz resonator pressure transducers for use in subterranean boreholes include a quartz pressure sensor and an electronic temperature sensor. Temperature sensors include a constant current generator, a proportional to absolute temperature (PTAT) current generator, and a relaxation oscillator. Pressure transducers may include such a temperature sensor. Methods of monitoring pressure in a subterranean borehole may include monitoring a frequency output of a quartz pressure sensor and monitoring a frequency output of an electronic temperature sensor.
