Precautions
◆
Operating Environment
●
Surrounding Atmosphere
• In order to maintain operating reliability, do not use or keep
the Sensor in locations outside the specified temperature
range, or in outdoor locations.
• Although this product has waterproof specifications, do not
use it in locations where it will come into direct contact with
liquids (e.g., water or cutting oil). Such locations can inter-
fere with the electrostatic capacity method used by the
Sensor.
• Do not use the Sensor in locations where chemicals (in
particular, solvents or strong acids) are present in the
atmosphere.
• Even if the Sensor is used within the specified temperature
range, do not subject it to sudden changes in temperature
because this will shorten the service life.
◆
Miscellaneous
• Drift may occur when the power supply is turned ON. If the
dielectric constant of the liquid is low, the detection level of
the liquid may be 2 to 3 mm higher than the set level for
approximately 20 minutes after power is turned ON.
