The Rosemount Thermal Optimizer allows for pressure measurement with increased process temperatures in low ambient climates.
The Rosemount Thermal Optimizer is an ideal solution for high temperature gauge pressure applications.
​
The Thermal Optimizer is not used to dissipate heat. It is used to conduct heat from the process to the fill fluid. This keeps the fill fluid at a temperature where it will be less viscous when installed in ambient temperatures below the normal operating ranges of the fill fluid (i.e. -50°C in northern Canada).
