Sensors

Contegra manufacturers analog and discrete level sensors.

  • Analog

  • An "Analog" sensor's output is continuously variable over the sensor's pressure range.  
    • Submersible:   Submersible transducers are typically used in Sewage Sumps and Ground Storage Tank.          Go to Submersible >
    • Ultrasonic:   Ultrasonic transducers transmit short busts of sound and measure the time required to hear a returning echo.  Contegra's transducer converts the 'time-of-flight" into an industry standard 4-20 mADC output.          Go to Ultrasonic >
  • Discrete

  • The "sensor" is typically a float switch that's mounted at a fixed location.  A rising/falling liquid level causes the switch contacts to Open/Close.
    •  FS 90 (Direct Acting Float Switch):  Contegra's FS 90 is made of Type 316 stainless steel.  The 5.5" float body is incredibly durable and provides significantly more buoyancy than the typical plastic float.      Go to FS 90 Non-Mercury >   
    • Dry Well Flood:  Contegra's FS 202 mounts to the wall of the pump station's dry well.  Should a leak occur, a slight rise of the FS 202's float causes the alarm contact to transfer.
