Superior stability and reliability
for demanding pressure
measurement applications
Overview
The Brooks® SolidSense II® pressure transmitters 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 transmitters 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 transmitter to rectify errors requires ongoing maintenance that increases
downtime and cost of ownership.
The third generation SolidSense II pressure transmitters by Brooks Instrument utilize
glass-fused strain gauge technology enabling a new level of performance for micro
electronics and industrial applications.
SolidSense II pressure transmitters 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
operational environment.
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.
