The Sondor measures the product height in a silo. It can work for any bulk product and does not require any adjustments after being put into operation.
Easy to install, it is used in industries storing granular or powder bulk and particularly in difficult applications: important height, turbulence, temperature, clogging bulk.
Under automatic or manual (push button) operating conditions, the measuring tape, previously wound up on its pulley and ballasted with the counter-weight, goes down into the silo. When this counter-weight reaches the material, the motor stops and runs back. The inductive sensor located in front of the pulley generates pulses they are transformed by the PLC into an analog output.
Technical Characteristics :
CONCEPTION
The SONDOR III is divided into two separate tight compartments :
The electrical compartment :
The motoreducing gear
The static proximity detectors
The relays and thermal protection
The transformer and protection in the form of fuses
The PCB electronics or the PLC control compartment
The mechanical compartment :
A gear motor
A measuring tape in stainless steel
An adjustable and dismountable scraper
A sealing rubber cone
A removable attach between slope and counter weight
A counter-weight can be filled up with the product to be measured.
The shape of the mechanical compartment makes the discharge of dust possible during evacuation.

FUNCTIONS
SONDOR III
Start operation
By push-button or
automatically frequency defined with customer
Output signal
Analog output 0-10V
Analog output 4-20Ma
pulses or profibus communication
Defect signal
General defect contact
Sequence safety
Control of the total times, self monitoring of all data points and cycle initialization
Thermic controls (gear motor)
Initialization after defect
Measurement reliability
Pulses counted on the way down are stored are counted on the way up and then compared. In case the difference exceeds 4 pulses, the measurement is not effective and a new cycle starts again.
Measurement accuracy
Automatic corrections of the variable winding diameter according to the number of rounds
Oversank operation
Automatic
Setting
Full or empty
Inhibited height and total height
Temporization for starting
Programmation
