Permanent Monitoring
Quartz Sensor
The Permanent Quartz Sensor is designed to provide operators with high quality real-time pressure and temperature data. It is a permanent monitoring system and downhole sensor. When accuracy, resolution and long term pressure-temperature stability is a prerequisite, you can count on the Canada Tech's Quartz sensor every time.
This tool uses the same proven Piezo-Resistive sensor and acquisition electronics as a number of other Canada Tech’s pressure tools. It provides accurate and reliable data acquisition in a cost-effective and convenient package and is available for pressure ratings from 50psi – 20,000 psi and temperatures from 50°C - 150°C.
