As a result of the design update, application of new Assembly technologies and mathematical processing, downhole quartz pressure and temperature transducers provide high accuracy (up to ± 0.03% FS), resolution and stability of measurements for long-term use in "hard" conditions.
And are used in monitoring and control systems for the study of gas and oil wells and reservoirs, submersible telemetry systems designed to work in the process of oil production.
