| MODEL 4082 Liquid Level Controller |
| Series 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 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 20mA equals 34.6 feet. A liquid crystal display (L C D) is provided to show the water level during normal operation, and the setpoint values during calibration. There are eight user-adjustable trip setpoints. 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 re-scaled 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 setpoints, and overall system operation. |
