SolidSense II® Series

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.

Features

Materials: Pressure transmitter features annealed VIM-VAR 316L stainless steel body with one-piece, machined sensor.
No welds or joints with dissimilar materials
Pressure range: 30 to 3000 psi full scale
Models available with integrated display or full-function programmable display
Digital thermal compensation uses multi-point temperature-compensation method
Proprietary micro-machined silicon strain gauges exhibit very low zero drift
Fully swept flow path completely removes residual gas
Outputs: 4 to 20 mA, 0 to 10 Vdc, 0.05 to 5.05 Vdc
