Downhole Gauges: Roxar, Sapphire & Quartz
BlueFin now offers downhole gauges that digitize pressure and temperature data downhole and then transmit to the surface using a high speed, digital telemetry link. Gauges available include:
Roxar Gauges, the proprietary high pressure, high temperature permanent monitoring system
Spartek's Permanent Sapphire Pressure Gauges, which uses proprietary piezo-resistive technology
Spartek's High Temperature Permanent Quartz Pressure Gauge which uses a high-resolution digital quartz pressure transducer with proprietary hybrid technology
