mounting hardware that is available through Emerson.
3.7.4 Output units
The snsr 1 unit and snsr 2 unit commands set the desired primary variable units. The transmitter output
can be set to one of the following engineering units:

Degrees Celsius

Degrees Fahrenheit

Degrees Rankine

Kelvin

Ohms

Millivolts
3.7.5 Sensor 1 serial number
The serial number of the attached sensor can be listed in the sensor 1 S/N variable. It is useful for
identifying sensors and tracking sensor calibration information.
