Rosemount 751
August 2014
The Rosemount 751 Field Signal Indicators provide a means of
displaying important process variables. These devices operate
with any two-wire transmitter that measures input variables
such as pressure, flow, liquid level, or temperature. Rosemount
indicators are ideal for installations where an integral meter
would be difficult to view.
Rosemount 751 Indicators are designed for use in industrial
environments where all-weather performance is necessary.
These units are vibration- and corrosion-resistant, and
explosion-proof or intrinsically safe. An LCD display meter or
analog meter may be ordered to meet specific application
requirements.
LCD display meter
The LCD display meter may be configured from a 4 mA point of
–999 to a 20 mA point of 9999 with a linear or square-root
response. A 20-segment bar graph at the bottom of the display
directly represents the 4–20 mA signal.
Changing the 4 mA and 20 mA points is easy. Just remove the
housing and meter covers, and press the meter faceplate
buttons. The meter can be rotated in 90-degree increments
within the enclosure for convenient viewing.

cover removed).

Analog meter
With the analog meter, several meter scaling options are
available to suit special application requirements with ±2
percent of calibrated span accuracy. Linear 0 to 100 percent
meter scaling is adequate for the majority of measurement
applications. With a flow transmitter, a logarithmic 0 to 100
percent flow scale is available. As an option, the user can specify
special meter scaling for direct readout in psi, gph, °F, °C, or
other convenient engineering units.
