Level limit switch Capcont LS

Application

• liquids and solids within container or pipes
• also in explosive hazardous areas
• process temperatures from – 40°C to +140°C
• process pressures from –1 up to 10 bar.
• with metallic gasket and rod isolation in PEEK is especially suitable for the use in hygienic applications

Function

The device is a capacitive operating sensor for limit value detection. Electrode rod, filling material and container wall creates an electrical capacitor. The contact of the electrode rod with the filling material produces a variation in capacity. That is evaluated by the electronic and converted in a correspondent switching action.
The detection of a filling level signal is indicated at the plug side of the device by a yellow LED and converted into a switching command and output at the PNP switching output. This allows the drive of relays, contactors, magnetic vents, optical indicators, horns as well as of SPS inputs.
At a switching reaction, the voltage of the connection terminal 1 (+L) is output alternating by two contrary operated semiconductor switches at two connection terminals. The adjustment of the responsitivity of the device to the respective filling material is done by a potentiometer.
Capcont LS is mounted from the top side of the pressure container or of the pipe. Capcont LL is mounted from the top side or into the side wall of the pressure container or of the pipe.
