Application calls for a 72" NPT coaxial
probe in water with the bottom of the
probe 10" above the bottom of the tank. The
user wants the 4 mA point at 24" and the
20 mA point at 60" as referenced from the
bottom of the probe.
When all measurements are referenced from the bottom of the vessel, the value of Lvl
Ofst should be changed to the distance between the bottom of the probe and the bottom
of the vessel as shown in Example 2.
Example 2 (Lvl Ofst = 10):
Application calls for a 72" NPT coaxial
probe in water with the bottom of the
probe 10" above the bottom of the tank.
The user wants the 4 mA point at 24" and
the 20 mA point at 60" as referenced from
the bottom of the tank.
When the SITRANS LG200 transmitter is mounted in a chamber/bridle, the unit is usually
configured with the 4 mA (0%) point at the lower process connection and the 20 mA
(100%) point at the upper process connection. The span is the center-to-center
