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.

Dynamic performance

The response time is defined as the time before output reaches

63.2% from an input change.

The response time is minimum.

Zero and span adjustment

Zero and span values can be set anywhere within the range. Span must be greater than or equal to the minimum span.

Output

Failure mode alarm

If self-diagnostics detect a sensor or microprocessor failure, the analog signal is driven either high or low to alert the user. The values to which the transmitter drives its output in failure mode depend on whether it is configured to standard, NAMUR-compliant or customer levels. The values for each are as follows:
