Quartz Pressure Gauge
High Temperature, Conventional Permanent Monitoring Systems
Product Description
BlueFin’s High-Temperature Permanent Quartz Pressure Gauge uses a high-resolution digital quartz pressure transducer with proprietary hybrid technology to digitize pressure and temperature frequency data downhole and then transmit to the surface using a high-speed digital telemetry link.
Along with a fully welded corrosive-resistant alloy design and redundant pressure testable metal-to-metal cable head, the Permanent Quartz Pressure gauge is ideally suited for long-term data quality and reliability.
Gauges connect to the carrier using a pressure testable AUTOCLAVE metal-to-metal seal connection. The 1/4” TEC cable connects to the gauge using a choice of “cableheads” - 1/4” or 1/8” - in addition, a pressure testable cablehead is available using 1/4” TEC cable.
