* Stable detection will not be possible in the following cases. Confirm detection capability with the Sensor installed before actual application.
1. If the specific inductive capacity or the specific electric conductivity of the liquid is too low, the liquid position may not be detected since this sensor is a capacitive
sensor.
2. If the quantity of liquid is too low or the change in quantity is too low in comparison to the change in liquid level because the pipe is too thin or the walls of the pipe
are too thick
3. If there is a viscous film on the inner pipe wall, large quantities of foam or air bubbles, or excessive buildup of dirt on the inner pipe wall

● Mounting
● Design
Mounting
Influence of Surrounding Objects
Mount the Sensor securely to the pipe using the enclosed two bands
and four slip-proof tubes (two tubes used for each band) as shown in
the following diagram.
When mounting the Sensor, be sure the entire Sensor is tight against
the pipe along the sensing surface.
When mounting the Sensor, maintain at least the distances in the
following diagrams from surrounding metal objects or other
conductors to prevent the Sensor from being affected by objects other
than the sensing object.

● Wiring
● Operating Environment
Power Supply
Ambient Atmosphere
• If the load and Sensor are connected to different power supplies,
always turn ON the Sensor power first.
• Switching noise can cause operating mistakes if a commercial
switching regulator is used. When using a switching regulator,
always ground the frame ground terminal and the ground terminal.
• Although the Sensor is water resistance, it is a capacitive sensor
and should not be used where it will come into direct contact with
liquids, such as water or cutting oil.
• The life of the Sensor will be shorten by rapid changes in
temperature even within the ambient operating temperature range.
Do not use the Sensor in locations subject to rapid temperature
changes.
● Miscellaneous
Drift will occur when the power supply is turned ON. If the specific
inductive capacity of the sensing liquid is low, the detection level may
increase by 2 to 3 mm during the 20 minutes required from the time
the power supply is turned ON until operation stabilizes.
