Omron E7B User manual

Capacitive Level Sensor E7B

Compact, High Sensitivity Level Sensor

Uses Capacitance to Detect Product

Submersible oil resistant construction for use in

aggressive environments.

Low mutual interference enables close mounting of

multiple units.

Installation with E7U controller provides dual sensor

control for dependable high–low level control.
