A.3.1 Material selection
Emerson provides a variety of Rosemount product with various product options and
configurations including materials of construction that can be expected to perform well in a
wide range of applications. The Rosemount product information presented is intended as a
guide for the purchaser to make an appropriate selection for the application. It is the purchaser’s
sole responsibility to make a careful analysis of all process parameters (such as all chemical
components, temperature, pressure, flow rate, abrasives, contaminants, etc.), when specifying
product, materials, options and components for the particular application. Emerson Process
Management is not in a position to evaluate or guarantee the compatibility of the process fluid
or other process parameters with the product, options, configuration or materials of
construction selected.
A.3.2 Tank connection and probe
Tank connection
The tank connection consists of a tank seal, a flange, Tri-Clamp, or NPT or BSP/G threads.
The PTFE covered probe with plate design has a protective plate in PTFE and a backing flange in
316L / EN 1.4404. The protective flange plate prevents the backing flange from being exposed
to the tank atmosphere.
