The Brooks® SolidSense II® Pressure Transducers are designed for stable, accurate, and
reliable pressure monitoring in high purity and ultra-high purity (UHP) applications. A
combination of optimum design and materials improves both signal stability and reliability
in numerous pressure measurement applications.
Pressure transducers are widely used in high purity and ultra-high purity fluid storage and
delivery systems in many industries. Unfortunately, a number of current transducers rely on
technologies that have problems with zero and span drift, thermal shift, and case stress.
Adjusting the transducer to rectify errors requires ongoing maintenance that increases
downtime and cost of ownership.
The third generation SolidSense II pressure transducers by Brooks Instrument utilize glassfused
strain gauge technology enabling a new level of performance for micro electronics
and industrial applications.
SolidSense II pressure transducers employ ultra stable, micro machined silicon strain gauges
that are matched and fused to the metal diaphragm at high temperature to relieve
manufacturing induced stress. The process reduces drift or lack of zero stability commonly
associated with competitive products. Consequently, down time for zero adjustment to
compensate for drift is significantly reduced. In addition, the unique mechanical design
eliminates torque effects during installation.
SolidSense II digital architecture enables automated software driven calibration and a wide
range of thermal compensation routines, unlike the passive compensation used in
competitive devices. This enhances measurement repeatability regardless of changes to the
SolidSense II devices feature 316L stainless steel wetted surfaces electropolished to
5- and 10-micro in. (5- and 10-Ra) to maintain the purity of the measured fluid.
