Rosemount 2051L Liquid Level Transmitter
Rosemount 2051 liquid level transmitters combine the 2051 transmitters with the
durability and reliability of a direct mount seal all in one single model number.
Level transmitters can be ordered with an additional Rosemount 1199 remote
seal to form a Tuned-System Assembly for improved performance and reduced
costs compared to traditional (balanced-symmetric) assemblies
Product features and capabilities include:
2051L Liquid Level
Transmitter
•
Variety of process connections
•
Quantified performance for the entire transmitter / seal assembly
(QZ option code)
•
4-20 mA HART, 1-5 Vdc HART low power and FOUNDATION fieldbus and
PROFIBUS PA protocols

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. High or
low failure mode is user-selectable with a jumper on the
transmitter. The values to which the transmitter drives its output in
failure mode depend on whether it is factory-configured to
standard or NAMUR-compliant operation. The values for each are
as follows:
Standard Operation
Output Code
Linear Output
Fail High
Fail Low

3.9  I  20.8
