Signature

Quartz gauge

Qualified to 437 degF and 30,000 psi

Even at the extremes of pressure and temperature, Signature quartz gauges ensure that the quality of your test data is never compromised. The large memory capacity accommodates high data sampling rates for a more comprehensive dataset. Signature gauges are powered by long battery life so you can continuously acquire the high-quality measurements you need for the duration of the test.

Signature gauges provide accurate, high-resolution pressure measurements

Accurate, high-resolution pressure measurements in all operating environments—including hostile HPHT conditions

How the Signature CQG Gauge Works

Rugged gauges for a complete dataset every time

Signature gauges feature a durable all-ceramic multichip module, securely housed in a welded steel housing to prevent contamination and safeguard the data stored on memory chips. The proprietary battery design and robust packaging resist high pressure and shock, ensuring service life of up to 1 year.

Wireless delivery for real-time pressure data
Run Signature gauges with the Quartet downhole reservoir testing system for high-frequency measurement. Signature gauges can be enabled by Muzic wireless telemetry to deliver pressure measurements in real time for detailed monitoring of test progress downhole. Each gauge can be interrogated independently for real-time or historical pressure or temperature data.
