Update to Product Reliability Testing

Quality and reliability will always be the top priority when designing and manufacturing a Quartzdyne transducer. Quartzdyne has demonstrated our commitment to quality through the extensive testing that a transducer is subjected to before leaving our facility. A decade ago a gap in the hybrid circuit quality was a motivating factor in developing a qualification test for the hybrid circuits. This test has been used, which is referred to as Lifecycle, to help validate updates in technology and ensure quality of the manufacturing process.  

Over the past two years, Quartzdyne has participated with several other stakeholders in the Oil and Gas industry to create a standard for launching products and product updates. The collection of stakeholders is the Advanced Well Equipment Standards Group (AWES). In January of 2016, AWES released a document of Recommended Practices for the Qualification of Downhole Instrumentation/Sensors. The testing practices in this document provide a robust statistical method for product qualification. Therefore, beginning in January 2017, Quartzdyne will discontinue Lifecycle testing and adopt the recommended methods of testing proposed by AWES. Positive or negative, we value your feedback and would invite comments or opinions regarding this change to be sent directly to sales@quartzdyne.com

 

Quartz Transducer Drift Characterization

While the drift at maximum conditions is specified to be less than 0.02 %F.S.  per year, questions regarding the typical drift at non-maximum conditions have arisen. This document discusses a study performed by Quartzdyne inc., designed to quantify the expected drift of a Quartzdyne transducer when operating under a variety of pressure and temperature conditions. In this study, more than 160 transducers were tested over a range of pressures and temperatures, amounting to more than 20,000 unit-test-hours.  The graphs below provide a high level summary of what we discovered.  If you would like to learn more, please click here to view the complete report.
