Omron E32-D82F Datasheet

Fluid level sensor (contact type)
E32-D82F
High-accuracy detection of
fluid level in washing tank.
● Uses Teflon (PFA) with excellent chemical and oil
resistance.
● Capable of detecting high-temperature fluids
such as sulfuric acid in a wafer washing tank.
(-40 to +200°C)
● Achieves a high repetition precision of 0.5 mm
(in pure water).
● Employs a dripping prevention mechanism.

*1. Teflon is a registered trademark of Dupont Company and Mitsui Dupont Chemical Company for their
fluoride resin.
*2. Only applies to Teflon section; the standard requires no bubbling when air at 98 kPa is injected for 30 sec-
onds at a depth of 100 mm in water.

Principle of operation
E32-D82F2
• In air, the difference between the index
of refraction of the Teflon section and
that of air is larger, and the light is
reflected by the detected surface and
returns to the light receiver.
• In the fluid, there is almost no difference
between the index of refraction of the
Teflon section and that of the fluid, and
the light radiates into the fluid.
