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.
