SolidSense II® Pressure Transducers

Maximize process precision with accurate, stable, ultra-high purity control.
Models GF / GI

For measuring pressure in ultra-high purity and specialty gas applications across many industries, pressure transmitters and transducers must maintain stability and accuracy. That's why Brooks Instrument SolidSense II® high pressure transducers combine weld-free, corrosion-resistant materials along with a design that delivers outstanding zero stability and accuracy within 0.25% of full scale.

We avoid the problems of zero and span drift, thermal shift and case stress that lead to maintenance and downtime issues with competitive high pressure transducers. Instead, SolidSense II® instruments deliver a robust, easy-to-maintain design that lowers the total cost of ownership.
