Oil resistance/chemical resistance (E3S-CL2)
For the oil resistance ofE3S-CL2, the Sensor has passed
tests on the oils given in the following table. Refer to the table
for examining the oil to be used. Depending on the oil type,
however, the Sensor may not be able to exhibit its perfor-
mance.

Note: 1 . E3S-C was submerged in the oils in the above table at 50°C for 240
hours, and passed the test of 100-M or more insulation resistance.
2 . For use in the environment where E3S-C is exposed to the oil other
than those in the above table, use the dynamic viscosity and PH in the
above table. Pre-check the oils since the sensor may be affected by
additives etc. in the oils.
