Descripción
1.1 Indicaciones para su aplicación
The vibrating level indicator ILV-660 is to be used to control the
maximum or minimum level of bulk solids in silos or vessels.
It is recommended for dusty and powdery, granulated and grainy
bulk goods like dust, flour, grain, sand, plastic, etc.
1.2
Funcionamiento
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 fork, it returns to the normal
vibrating state and the signal turns to the initial position.
The device has a insensitive rod between the probe and the
proccess connection to avoid the possibility of settle of the product
over the probe up to 75 mm.

Installation
2.1 Preparing for use
The probe must not be hit by the filling stream. To avoid this,
deflect the filling stream or install a deflection screen or a
protection roof. It is also recommended to install a protection roof
when the controllers are used as empty-indicator or medium-
indicator in silos where vaults could be formed or where high
loads above it could exist.
For a proper function, the device should be installed with a 20 º to
30 º 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.
Read the Safety instructions and the Operating instructions before
using the controller.
