ILV-130

Control of solids
Vibrating level indicators

Intended use

Vibrating level indicator with probe and protection tube shaft for normally vertical mounting or inclined mounting depending on the material. Strong and multivoltage model, with sensitivity adjustment and detection type adjustement.

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.

Function

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.

Mechanical connection

The device can be mounted horizontally or vertically depending on the model.

The normal installation is by screwing the device onto the deposit wall, with a mounting flange or with an appropiate support to fix it. For a proper function, the device should be installed with a 20º to 30º slope from the horizontal onto the silo wall to to facilitate the flow of the material and to prevent the material from remaining over the probe. The correct position of the probe is when the marks in the proccess connection are up and down. With this position there is a prevention of damage to the probe due to the material weight.
