Description
The Model 4082 Liquid Level
Controller monitors, displays and controls water level up
to 34.6 feet in a tank or reservoir.
The Model 4082 Liquid Level
Controller operates from the 4-20ma input signal provided
by either the Time Mark Model 450 or Model 456-15 Pressure
Transducer. This 4-20ma signal represents the water level
to be controlled, where 4ma equals
zero feet, and the 20ma equals 34.6 feet. A liquid crystal
display (LCD) is provided to show the water level during
normal operations, and the set-point values during calibration.
There are eight user-adjustable
trip set-points. As the water level rises above each trip
point setting, the front panel LED for that level illuminates,
and the corresponding output relay energizes. Two 4-20ma
outputs, which track the 4-20ma input, are also provided.
These signal outputs can be rescaled to different ranges
of level by the
user. A test control, that simulates an input signal, is
available on the front panel. The test control is useful
for checking the trip set-points, and overall system operation.
