Quartzonix™ pressure standards use a patented monolithic quartz
structure and vibrating beam to measure pressure-induced stress. The beam's
frequency of vibration changes by pressure induced stress that is applied to the
beam via a miniature metal bellows. The bellows isolates the quartz sensing
element from the applied gas, thereby making the sensor insensitive to gas
density. The Intelligent QuartzonixT has a resolution of up to .00007% FS, and
drift rates of less than 0.01% FS over a 6-month period.
The Model 970 uses a
multi drop, 9600 baud ASCII character RS-485 type interface, allowing a network
of up to 31 transducers on the same bus. The 970 can also be configured by the
user for RS-232 communication. The measurement units and the update rate are
both user-programmable. The 970 is capable of up to 12 readings per second. The
extremely low power consumption design with a programmable sleep mode makes the
Intelligent QuartzonixT ideal for remote battery powered applications.
