4.2 Installation considerations
The information in this section covers installation considerations for the Rosemount 2240S Multi-input
Temperature Transmitter in order to achieve a proper installation and optimum measurement
performance.
In order to reduce the required cabling, Rosemount Tank Gauging devices, including the Rosemount
2240S, are designed for daisy-chain connection of the Tankbus and shield grounding to other field
devices.
The Rosemount 2240S is designed for installation:

on top of the MST/WLS

remote on a pipe or wall
With remote mounting of the Rosemount 2240S, the nut and sleeve at the bottom of the 2240S can be
replaced by a M32 cable gland, see
“Components” on page 8 and “Ordering information” on page 146 .
When the Rosemount 2240S transmitter is installed in a hazardous area, ensure that the installation
requirements according to
“Hazardous areas” on page 36 are complied with.
Ensure that the recommended cable glands/conduits are used.
Ensure that the Tankbus is correctly terminated, see “Termination” on page 37 .
Ensure that grounding is performed according to national and local electrical codes, see “Grounding” on
page 34 .
Do not install the Rosemount 2240S in non-intended applications, for example environments where it
may be exposed to extremely intense magnetic fields or extreme weather conditions.
Ensure that the Rosemount 2240S is installed such that it is not exposed to higher pressure and
temperature than specified in
Appendix A: Specifications and Reference Data .
It is the responsibility of the user to ensure that the device meets the specific inside tank installation
requirements such as:

chemical compatibility of wetted materials

design/operation pressure and temperature
