New Leadership at Quartzdyne
We track our field reliability by recording failure modes and year shipped for each returned transducer. Each year we analyze the findings for trends, and share the results openly on our webpage. This report describes the general design of a Quartzdyne pressure transducer, and provides the reliability statistics and common failure modes for each of the major components.

As part of an ongoing effort to increase reliability of our quartz pressure transducers, Quartzdyne has undertaken a miniaturization effort with our hybrid circuit assemblies. Prior to this effort, hybrid circuits were installed inside a gold plated Kovar “boat” assembly, which included a welded lid, to create a hermetically sealed environment. Starting with the Saqqara hybrid package (Frequency), Quartzdyne “unitized” the circuit assembly, thus eliminating the bottom of the “boat” assembly and using the circuit substrate as the lid of the sealed package.
Once this was complete, Quartzdyne launched a project to convert the digital circuit to the same unitized package. This effort resulted in a hybrid circuit assembly that has 46 fewer interconnects, no substrate-to-boat I/O bonds, and 17 fewer components than its predecessor. We plan to include this product in our digital transducer starting in Q1 of next year. Please contact us for more information.
In October 2014 Quartzdyne announced the release of the world’s first ½” diameter resonant Quartz pressure transducer. This transducer incorporated our new, significantly smaller, precision Quartz pressure sensor and related mechanical features. The limitation of this transducer was that it used the hybrid circuit from our larger ¾” transducer, preventing the transducer from fitting into a “true” half inch envelope. This limitation has now been remedied with our new DHB series “true” ½” pressure transducers. Featuring a much smaller hybrid circuit with low profile silicon chips and a new, more robust, pressure fitting. The same precise, accurate performance you have come to expect from Quartzdyne, but in a considerably smaller package.
Dr. Rick Puccio, our Sr. Staff Scientist provided a presentation on Quartzdyne's next generation Quartz transducer during the most recent SPWLA conference held at Chevron's headquarters in downtown Houston. Dr. Puccio spoke about the critical performance factors that Quartzdyne is addressing with new technology, to improve the overall performance of the transducer. Key aspects of the presentation include transient response, transducer size reduction, and long term drift. Please take time to review the presentation, and contact us if you have questions or would like additional information.

Quartzdyne invites you to visit us, in booth 3130 during the Offshore Technology Conference and Exhibition in Houston, Texas. Please contact us at email@example.com if you would like a complimentary one-day pass. We look forward to seeing you there.
After 23 years of dedicated service, including 7 years as President, Lon Perry decided he was ready for a new adventure. Last fall Lon announced he would be leaving Quartzdyne to pursue new interests and a second career. We are grateful for his many contributions to the success and culture of Quartzdyne and wish him all the best in his future pursuits.
Glenn Small has been selected to lead Quartzdyne as its new President. He has worked at Quartzdyne for 5 years in Sales and Business Development. Glenn holds an MBA from Brigham Young University and a BS in Mechanical Engineering from Utah State University.
Ryan Roush has been promoted to Director of Engineering after the recent departure of Scott Brown. He has been with Quartzdyne for 4 years as our Lead Electrical Engineer. Ryan holds an MBA from Westminster College and a BS in Electrical Engineering from the University of Utah.
The new leadership at Quartzdyne is committed to growing Quartzdyne’s legacy of reliability, performance, and continuous improvement.
