38 46-648 Jupiter Magnetostrictive Transmitters
Nonhazardous Area An area where no volatile mixtures
of vapors/gas and oxygen will be found at any time. Also
called General Purpose Area.
Non-incendive Equipment and wiring which in its nor-
mal operating condition is incapable of igniting a specific
hazardous atmosphere or hazardous dust layer.
Offset The distance from the bottom of the tank to the
bottom of the probe.
Password A numerical value between 0 and 255 that
protects stored configuration data from unauthorized
manipulation.
Percent (%) Output The present reading as a fraction of
the 16mA scale (4–20mA).
Poll Address A number between 1 and 15 which sets an
address or location of a device in a multi-drop loop.
Probe A waveguide that propagates an electromagnetic
pulse from the top of the tank into the process fluid.
Probe Length Exact measurement from the bottom of
the process thread connection to the very bottom of the
probe.
Range A value related to probe length (factory setting).
Repeatability The maximum error between two or more
output readings of the same point.
RFI Radio Frequency Interference Electrical noise that
can have an adverse affect on electrical circuits, particular-
ly low-power devices.
Span The difference between the upper and lower limits
of the range.
Specific Gravity (SG) The ratio of the density of a mate-
rial to the density of water at the same conditions.
Tst Loop Test Loop Built-in system capability to
test/calibrate a loop (or separate loop device) by driving
the transmitter output to a particular value.
Trim 4/Trim 20 Built-in system capability to fine tune
the 4 mA and 20 mA points so the transmitter output
corresponds exactly to user’s meter, DCS input, etc.
Two Wire An electrical instrument design that uses one
set of wires to provide both the supply power and process
measurement signal. The process measurement is achieved
by varying the current of the loop. Also called Loop
Powered.
Units The engineering units used to measure level in the
system. The choices are in (inches) and cm (centimeters).
