Sapphire Gauges
Proprietary piezo-resistive technology to digitize pressure & temperature data downhole
Permanent Sapphire Pressure Gauges use proprietary piezo-resistive technology to digitize pressure and temperature data downhole and then transmit to the surface using a high speed, digital telemetry link.
Gauges connect to the Carrier using a Pressure Testable AUTOCLAVE metal-to-metal seal connection. Several designs are available as tubing-ported or annular-ported built as Full Body Carriers, Machined Coupling Carriers or Welded Lug Carriers.
The TEC cable connects to the gauge using a choice of “cable-heads” – sweet or sour, 1/4” or 1/8” – in addition, a range of pressure testable cable-heads are available when using 1/4“ TEC cable.
The surface acquisition unit (SAU) provides power and acts as a memory for downhole gauges in permanent completions as well as providing the communications hub for SCADA or real-time transmission. The SAU links to the gauges downhole through the Tubing Encapsulated Cable (TEC) and the Well-Head Outlet (WHO). The SAU can also be used to program and interrogate the downhole Permanent Pressure Gauges.
