Analog ultrasonic sensor

For lubricant tanks with a capacity of more than five liters

The virtually maintenance-free SKF sensor uses ultrasonic waves to non-contactly measure the distance to an object—the lubricant surface. Depending on a preset value range, it generates an analog signal proportional to the distance to the lubricant. Two color LEDs indicate the sensor's operating status and analog output.

Technical characteristics and advantages

  • Reliable control of the tank filling level
  • Easy maintenance
  • Improved pump monitoring
  • No blind spots in the tank
  • Analog output
  • Continuous level measurement
