Vibrating level indicator with probe and rope shaft for vertical mounting. Strong and multivoltage model, with sensitivity adjustment and detection type adjustement. Versatile, with a wide range of applications.

To be used to control the maximum or minimum level of bulk solids in silos or vessels and recommended for dusty and powdery, granulated and grainy bulk goods like dust, flour, grain, sand, plastic, etc. with a minimum bulk density from 0.01 t/m3.

The probe must to be exposed to the material. The probe of these controllers is activated to its resonant frequency by a piezoelectric system. When the product covers the probe, the vibration is dampened and the control unit reverses the signal.

When the product disappears from the probe, it returns to the normal vibrating state and the signal turns to the initial position.

The device has to be mounted vertically.

The normal installation is by screwing the device onto the deposit wall, with a mounting flange or with an appropiate support to fix it.
