Suspension Electrode HR-690121

Sensor for conductive limit value detection

Function

An electrode relay provides the measuring AC voltage for the electrode. If the product comes into contact with conductive batch, the measuring circuit between electrode and wall of vessel is closed and the electrode relay is switched.

Dimensions

The electrode is cylindrical with a total length (L) of 160 mm (6.3 inches) and a diameter of 20 mm (0.8 inches). The cable entry has a diameter of approximately 10 mm. The top diameter (D7) is also indicated.
