• 409-230

    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)

  • 4092-120

    Dual Seal Failure Detector

    The Model 4092 Dual Seal Failure Detector is designed specifically for monitoring the shaft seals of two submersible pumps. The probes are installed in the seal cavities of each of the pumps. When a seal begins to leak, contaminating fluid enters the seal cavity, lowering the resistance between the probe and the common connection. If the resistance drops below the sensitivity set-point, the corresponding relay and the LED indicator are activated. The Model 4092 will automatically reset when the fault condition is corrected. The sensitivity is field adjustable.

    Isolated Dual Seal Failure Detector

    The Model 4092I Isolated Dual Seal Failure Detector is designed specifically for monitoring the shaft seals of two submersible pumps. All electrical inputs are totally isolated from each other. The probes are to be installed in the seal cavities of each of the pumps. The sensitivity is field adjustable. When a seal begins to leak, contaminating fluid enters the seal cavity, lowering the resistance between the probe and the common connection. If the resistance drops below the sensitivity set-point, the corresponding relay and the LED indicator are activated. The Model 4092I will automatically reset when the fault condition is corrected.

  • 4093-120

    Liquid Level Controller

    The Model 4093 is a compact, socket mounted Liquid Level Controller that operates by monitoring the conductive liquid resistance between two probes. The unit monitors two liquid levels and responds as a pump-up or pump-down control as determined by the switch setting on the top of the unit. The green LED indicates pump operation while the potentiometer allows the user to adjust probe sensitivity.

    Liquid Level Controller
    11-Pin, DPDT

    The Model 409D 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, 300ms 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 11-pin octal socket (such as the Time Mark model 51X016).

  • 422

    Submersible Pump Controller

    The Model 422 Submersible Pump Controller detects an overload or underload condition on all types of running pump motors: suction pumps, submersible pumps, etc. This Monitor detects the actual power used (voltage x current x power factor) and is more sensitive than simple current monitors. The 422 can be used with single phase pumps or, using the Model 276C current transducer, with 3-phase pumps. Matching CTs allow the Model 422 to be used with most pump motor sizes. Optional trip and restart delays are provided.

  • 448

    Output Relay Board

    The Model 448 Output Relay Board provides electromechanical relay contacts for the Model 404 or 408 Liquid Level Sensors, allowing those models to be used as a control device. The Model 448 consists of a power supply and five relays on the surface-mounted printed circuit board. Four of the five relays are used with the Model 404. All five relays are used on the Model 408, refer to typical application. Some liquid level control applications may not require the alternating control, HOA switches, or run-time meters (see the Model 403 or Model 407 data sheets). The Model 404 and Model 408 Liquid Level Sensors uses the Model 448 to meet the needs of direct relay control applications.
