3.2 Description
Thedeviceisaprobetobeusedforsensingthelimitlevelof
electrically conductive liquid media, by contact.
• When the medium makes contact with the sensor rods, this
creates a conductive connection which is evaluated by the
electronics in the connector head.
• Sensitivity adjustment via the potentiometer
• Device installed in the vessel so that it is perpendicular to
the surface of the medium
• 2-rod probe for indicating the minimum or maximum filling
level
• 3-rod probe in the following variants depending on the cir-
cuit board installed:
– 2-state control unit
– Indicates the minimum and maximum filling level

5.1.1 Check operating conditions
1. Ensure the required operating conditions are met:
– Resistance of body and seal material to the medium
(→ resistance lists).
– Media temperature (→ Data sheet)
– Operating pressure (→ Data sheet)
2. Consult with the manufacturer regarding any other use of
the device.

1. Ensure the device is protected against ingress of moisture.
2. Cut the probe rods to length if necessary. Check the appli-
cation examples for the relevant type (→ 9.2.1 Description
of the contact points, Page 8 ).
3. Check that the uninsulated ends of the rods are not touch-
ingeachother.
