| MODEL 408 Liquid Level Sensor |
| Series Description: The Model 408 Liquid Level Sensor operates in conjunction with a Model 407 Controller for bubbler-type triplex pumping systems. The 408 contains an air pressure-to-voltage transducer and requires only a small compressor capable of 15 psi (pounds per square inch) to operate the system down to approximately 35 feet. The Model 408s five outputs are designed to replace the float switch inputs to a Model 407, or to be used with a Model 448 Output Relay Board. A 4-20 mA signal output provides for other control applications. A 3-digit LED display continuously shows the liquid level to a tenth of a foot when the Display Control switch is in the Liquid Level position. Other settings of the switch allow setting of the liquid level trip points. LED Indicators illuminate as the levels are exceeded. A test control allows the trip settings to be checked without actually raising or lowering the liquid level. |
