Environmental Considerations
To ensure maximum transmitter life, avoid excessive heat and vibration. Typical problem
areas:
• high-vibration lines with integrally mounted transmitters
• warm-climate installations in direct sunlight
• outdoor installations in cold climates.
Remote-mounted transmitters may be installed in the control room to protect the electronics
from the harsh environment and provide easy access for configuration or service.
Both remotely and integrally mounted Rosemount 8750WA transmitters require external
power so there must be access to a suitable power source.
Installation Procedures
Rosemount 8750WA installation includes both detailed mechanical and electrical installation
procedures.
Mount the Transmitter
At a remote site the transmitter may be mounted on a pipe up to two inches in diameter or
against a flat surface.
Pipe Mounting
To mount the transmitter on a pipe:
1. Attach the mounting bracket to the pipe using the mounting hardware.
2. Attach the Rosemount 8750WA transmitter to the mounting bracket using the mounting
screws.
Identify Options and Configurations
The standard application of the 8750WA includes a 4–20 mA output and control of the
sensor coils and electrodes. Other applications may require one or more of the following
configurations or options:
• Multidrop Communications
• Digital Output
• Digital Input
• Pulse Output
Additional options may apply. Be sure to identify those options and configurations that apply
to your situation, and keep a list of them nearby for consideration during the installation and
configuration procedures.
