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.
