  4092-120

  Dual Seal Failure Detector
  Read more
  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.

  4092I-120

  Isolated Dual Seal Failure Detector
  Read more
  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
  Read more
  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.

  409D-120

  Liquid Level Controller
  11-Pin, DPDT
  Read more
  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).

  410D-40J

  Auto-Charged Capacitor Trip Device
  40.4J of stored energy at 380V
  Read more
  The 410D Auto-Charged Capacitor Trip Device is a micro-controller based high speed capacitor type circuit breaker tripping unit. It differs from standard CTD’s in that has a separate charging circuit and is isolated from the mains.
  This device is primarily for use with circuit breakers which require some form of AC power for their closing operation; i.e. circuit breakers having either a stored energy closing mechanism with an AC-operated release coil, or an AC solenoid-operated closing mechanism. The 410D-40J has a stored capacity of 40.4J at 380V and can maintain a full charge for 48 hours.

  412

  Automatic Reverse Controller
  Read more
  The 412 Automatic Reverse Controller is a current sensor designed to detect jamming of sewage grinders and to initiate the reversing of the grinder. The controller allows the selection of up to five forward/reverse cycles, and provides for an alarm output, if the number of cycles is exceeded. The current loop inputs are designed for direct connection of 10 amps at 240 VAC, or 5 amps at 480 VAC (up to 2hp motors). For higher currents, a current transformer must be used (the CT secondaries are connected to the 5 amp terminals, regardless of voltage). A manual push-button is used to simulate an over current condition and to test the relay contacts and alarm. A current level adjustment is used to optimize the trip point setting. LED indicators show the running direction of the motor and the alarm condition.

  421

  Over/Under Motor Load Monitor
  Read more
  The Model 421 detects an overload or under-load condition on all types of running motors; conveyor motors, elevator motors, mixer motors, submersible pumps, suction pumps, etc. The monitor detects the actual power used (voltage x current x power factor) and is more sensitive than simple current monitors. The Model 421 can be used with single-phase motors, or using the Model 276C Current Transducer, with three-phase motors. Matching CTs allow the Model 421 to be used with virtually any size of motor. Trip and restart delays are provided; one or both can be turned on or off.

  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.

  441-120

  Multi-Stage Alternator
  Read more
  The Model 441 Multi-Stage Alternator is designed to control the operating sequence of multi-stage motor/pumping systems. It can also be used to maintain the desired level of pressure-on air compressor systems. Four motor select DIP switches located on the front panel allow the alternator to control a single-motor/pump, two-motor/pump, three-motor/pump or four-motor/pump system. The Model 441 will assure that only the necessary motors/pumps are operating, and that the run time for each motor/pump is approximately equal. Motors are sequenced first-on, first-off. If the motor/pumping demand requires only one motor/pump at a time, the alternator will start the next motor/pump in sequence each time an input switch is closed. Input switches may be float switches, pressure switches, flow switches, etc. , as required by the application.

  Potential uses for the Model 441 include water supply systems, sewage disposal plant systems, storage tank filling systems, air compressor systems, irrigation and water recycling systems.
