NEW: 1/2” (13 mm) Quartz Pressure Transducer
Product Launch: xHPHT Transducer (35k psi / 225 C)
New Drift Study
New ASIC Implementation
New Paper: Electronics for Harsh Environments
Message from the President
We are excited to announce the introduction of the world’s smallest resonant quartz pressure transducer. The ½” (13 mm) transducer was designed for applications that require high-accuracy, precision pressure measurements in tight spaces. This transducer has a better dynamic transient response than our ¾” (19mm) version. Its pressure port is a thread-and-cone autoclave that can be welded for permanent applications. For more details refer to the detailed print on our web page: Analog or Digital. Please contact us to order your ½” transducer today.
We are now accepting orders for our new xHPHT transducers. The need to look beyond conventional sources of oil and gas is an increasing reality of the industry. This growing need is driving demand for precision quartz transducers capable of pressures and temperatures beyond what is already considered to be HPHT. In response to the industry’s need, Quartzdyne has developed a proprietary quartz technology that enables the pressure transducers to perform in extremely high pressures and temperatures environments. Using that technology, Quartzdyne has launched transducers rated for 35,000 psia and 225°C. Quartzdyne is also targeting 40,000 psia and 260°C for the next phase of development.
In the past, Quartzdyne has published drift characteristics quantified at the maximum rated pressure and temperature for each transducer type. In response to customer requests, Quartzdyne engineers have been working to develop a more precise understanding of the pressure drift observed at intermediate operating pressures and temperatures. Table 1 summarizes the results of experiments completed thus far.

We continue to improve our products by developing application-specific integrated circuits (ASIC) that make our electronics more reliable, higher temperature, and smaller. Our latest ASIC combines three ICs and 23 passives into one chip, reducing the total component count inside the frequency-output (“analog”) hybrid from 29 to 4! This breakthrough took several years to engineer, with a couple “re-spins” to fine-tune the ESD protection and crystal oscillation. Due to the reduced component count, the analog circuit will shrink to one-third of its prior length. The I2C-output (“digital”) hybrid will likewise incorporate this new ASIC, but the digital package will remain unchanged until we integrate additional passives and memory into the digital chip. The new ASIC has survived over 1,000 hours at 275°C, and the accompanying transducers have passed our standard environmental qualification tests.
The reduced-size analog hybrid (pictured below) starts shipping next month, and the digital hybrid with the new ASIC will start shipping by April 2015.
Quartzdyne was invited to present at the “Rugged Electronics for Harsh Environments” workshop held at the A*STAR Institute for Microelectronics (IME) in Singapore. The workshop brought together engineers from Aerospace, Oil & Gas, Academia, and other Industries to present challenges and solutions in electronics, sensors, and packaging in rugged environments. Quartzdyne’s message focused on the benefits of integration in electronic design including: increased reliability, reduced size, and reduced component count. In addition to ASIC integration, a large custom MCM project was highlighted along with its technical challenges and solutions.

We strive to espouse four core values at Quartzdyne: Individuals, Integrity, Initiative, and Innovation. Valuing individuals includes caring for our employees’ health and safety. About one year ago, our 12-month rolling TRIR (total recordable incident rate) was 5.9, compared to an industry average of 1.2*. Since our accidents were minor in nature, we weren’t giving it much attention. It seemed that we were waiting for a “big one” before we got serious. Last year, a colleague told me about a man who was seriously injured under his watch. As a result, it affected the man’s health, his confidence, his income, and ultimately his marriage. When someone gets hurt, it can have long-term consequences on that individual’s physical, emotional, and financial well-being. Hence, safety affects the relationships that we care about the most.
Today, our TRIR is about 2.0. We’ve made progress in thinking and talking more about safety, and I’m pleased to see many of our kaizens focus on eliminating unsafe conditions. Yet, there is much room for improvement as we still have a reactive culture in many ways. Our goal is to reach and maintain a zero harm workplace. I’m confident that with continued focus on it, we’ll get there. Safe, healthy, happy employees cultivate better relationships at home and make better products at work.
