  408-24

  5-level Liquid Level Sensor

  The Model 408 is a 5-level liquid level sensor designed for use with bubbler-type systems. The 408 contains an internal air pressure transducer; the user must provide a small air compressor capable of supplying a maximum of 15 psi. This operates the system to a liquid depth of 34.6 feet. The output of the 408 connects to the inputs of the Model 407 3-Pump Liquid Level Controller (replacing the float switches) or to a Model 448 Output Relay Board. A 4-20mA signal output is provided as an input to process controllers or for other control applications. A 3-digit LED display continuously shows the liquid depth to 0.1 foot when the display control switch is in the Liquid Level position. Other switch positions allow setting of the corresponding trip level points. The trip points are set using coarse and fine adjustment pots, and are shown on the LED display. Each trip level has an LED indictor which illuminates as the solid-state output makes. A test feature allows the trip settings to be checked without actually changing the liquid level.

  662

  Pump Up Control

  The Model 662 Pump Up Control, part of the 600 series line of instrumentation controls, is designed to monitor andmaintain liquid levels. A user-provided 4-20mA current loop represents the liquid level, and output connections are provided for pump control. The HIGH ADJUSTsetpoint, and the LOW ADJUST setpoint, are field adjustable. If the input falls below the low setpoint, the PUMP UP relay energizes, and remains that way until the input rises above the high setpoint. The high setpoint must always be set above the low setpoint. Top-mounted LEDs on the Model 662 show system status. The PUMP UP LED turns ON when the input falls to 10% below the low setpoint, and resets when the input rises above this level. An INPUT LOOP ERROR LED turns ON if the input is outside the 4-20mA range. A Time Mark Model 650 Loop Power Supply (or equivalent) is required to provide the 24 VDC operating voltage.

  A Time Mark Model 672-15 Pressure Transducer (or equivalent) is required to provide the input signal.

  404-24V

  Liquid Level Sensor

  The Model 404 Liquid Level Sensor operates in conjunction with a Model 403 Controller for bubbler-type duplex pumping systems. The 404 contains an air pressure-to-voltage transducer and requires only a small air compressor capable of 15 psi to operate the system down to approximately 35 feet. The Model 404s four outputs are designed to replace the float switch inputs to a Model 403, or to be used with a Model 448 output Relay Board. A 4-20mA 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 lower the liquid level.

  409-120

  Liquid Level Controller

  8-Pin, SPDT

  The Model 409 is a compact, socket-mount device for level control of conductive liquids. The internal relay is energized when operating power is applied. When the liquid level reaches the probe, the relay de-energizes. When the level drops below the probe, the relay will reset. A fixed, two-second time delay prevents oscillation due to wave action. Probe cables may be shielded or unshielded. If the liquid container is made of a non-conductive material, a common electrode is required. Other features include an LED indicator to show the output relay status and an adjustable sensitivity setting.

  Requires a standard 8-pin octal socket. (socket number 51X00120-01)
