Legendary Rosemount performance customized for marine applications
The Rosemount 520 Level Transmitter is an all-titanium,
compact, reliable transmitter designed specifically to be
suitable for the harsh marine environment. The Rosemount 520
continues the Emerson tradition of delivering superior
performance, reliability and value.
Suitable for installation in virtually any tank gauging application with a comprehensive offering of installation kits
The flexibility in terms of a wide range of available installation
kits makes the transmitter suitable for all tank types, and the
all-welded titanium housing makes it compatible with all
commonly used liquids. Reducing the variety of different
transmitters used on-board the ship minimizes the cost
associated with design and installation.
Simplified ranges and up to 25:1 rangeability for increased flexibility
5-year stability guarantee reduces maintenance costs
Pressure transmitters can drift out of specification after just a
few months and require recalibration, which consumes both
time and money. The Rosemount 520 carries a 5-year stability to
reduce the frequency of calibration and reduce maintenance
costs.
Figure 1. Calibration Frequency Comparison
The rangeability allows you to cover a wide spectrum of
applications, level gauging from 0.8 mH
two transmitter ranges. This not only allows you to be flexible,
but also reduce inventories.
Superior overpressure protection
The superior overpressure capabilities ensure trouble-free
ownership. The transmitter is designed exclusively for harsh
marine applications, which reduces issues associated with, for
example, sloshing in the tanks.
