Hybrid Circuits

Quartzdyne specializes in designing, processing, manufacturing and testing high-temperature electronics that are used in permanent monitoring, intelligent completions, wireline/logging applications and measurement while drilling (MWD) systems across the oil and gas industry.

Some of our core technologies include the following:

The sensor is made of crystalline quartz , which is naturally piezoelectric. Quartz resonators use the inverse piezoelectric effect to induce the resonator to vibrate at its mechanical resonant frequency when electric fields are applied to its electrodes. An oscillator circuit supplies the power and allows the frequency to be measured. Because frequency (and its inverse, time) can be measured with greater precision than any other parameter, the sensor’s frequency output provides high resolution pressure measurement.

Quartz is a perfectly elastic material, providing sensor stability and repeatability. The quartz resonator has a high Q, which means that its vibration can be driven with very little electrical power. This provides long operating life in battery-powered applications.
