          High Power Digital Ultrasonic Sensors

          FW series

          Versatile Delection Modes

          Choose from 5 different detection modes.

          General purpose

          F-1 mode

          (General Purpose)

          Various sensitivity adjustments are available. For example, “two-point tuning” can be performed by pressing the [SET] button with or without the target in place, and “fullautomatic tuning” can be performed automatically while the operator moves the target.

          F-1 mode

          Targets with a background

          F-2 mode

          (Targets with a Background)

          This mode is useful when detecting a target with a background. The target height is displayed with the background as the reference. “One-point zone tuning” is available, which detects only targets at a certain height without detecting the background.

          F-2 mode

          Targets on a conveyer

          A-1 mode

          (Targets on a Conveyer)

          This mode is optimal for detecting the presence and absence of targets traveling on a conveyer. The target height is displayed with the conveyer as the reference. “Conveyer tuning” is available, which detects only the targets without detecting the vibrations of the conveyer. Output 2 serves as the alarm signal that detects unloading of the conveyer and other abnormalities.

          A-1 mode

          Detecting the liquid level

          A-2 mode

          (Target Liquid Level)

          This mode is suitable for detecting the liquid level. The height of the liquid level is displayed with the bottom of the tank as the reference. Two preset values (upper and lower limits) and two additional preset values for predicting the upper and lower values can be set up to enable monitoring the following four statuses: normal, near the upper limit, near the lower limit, and abnormality of upper and lower limits.

          A-2 mode

          Zone control

          A-3 mode

          (Zone Control)

          This mode is suitable for controlling the pump by detecting the liquid level in a tank, or for controlling the tension of sheet material. The height of the liquid level or the sheet can be displayed by setting the reference level as desired. Two preset values (upper and lower limits) can be set up to control the device: When the upper limit is exceeded, the output is turned off to stop the device, and when the lower limit is exceeded, the output is turned on to activate the device.

          A-3 mode
