CApACITIvE pROxIMITY SENSORS
Capacitive Sensors
Pepperl+Fuchs' capacitive sensors can be used to detect nonmetallic objects. These include liquids, such as acids,
and water; as well as granular materials, including grain, flour, and sugar. They are available in several housing
styles, including cylindrical, limit switch, and flat pack. Most are made of stainless steel or durable PBT, and feature
sensing ranges from 1 mm to 50 mm. They are ideally suited for "point" level control in flat-walled vessels and flow/no
flow indication in plastic tubing. Versions are available with PVDF housings offering chemical resistance and IP68 rating.

Sight Glass Mounts
This handy mount enables
the use of 30 mm diameter
capacitive sensors for level
control applications. Just slide
the mount over any glass or
plastic tube with a 25.4 to 44.5 mm diameter.
The mount makes it easier to adjust the sensor
without disturbing the fluid inside the tank.
Mounting Flanges/Sensor
