Elscint vibratory bowl feeder controller
Elscint Automation now offers soft start electronic controllers for vibratory feeders, specially designed for controlling the amplitude of vibration in industrial electromagnetic vibrators
Elscint Automation now offers soft start electronic controllers for vibratory feeders Two models are available: the E3FC, rated up to 360VA (mainly for linear feeders and smaller sized bowl feeders); and the E5FC, rated up to 800VA (for bowl feeders and large linear feeders)

Range of vibratory bowl feeders
Elscint manufactures 5 different models of Vibratory Bowl Feeders, for applications in the cosmetic, electrical, mechanical, pharmaceutical, optical, bearing and many other industries
Feed, sort and grade components fast
The Elscint sorting and grading unit is designed to feed, sort and grade components having cylindrical and spherical geometry like balls, rollers, needle rollers, gems, at a rate in excess of 150 ppm
The controllers are specially designed for controlling the amplitude of vibration in industrial electromagnetic vibrators.
The system is based on a integrated circuit which guarantees perfect synchronisation of the triac firing pulse with the waveform of the working voltage under all conditions.
The controllers also include a suitable circuit for soft start with provision for choosing the ramp time (0.2-2s) and for temperature compensation of the phase angle.
Appropriately over specified power stages are provided to handle any overloads without interruption, whether operating at 50Hz or 60Hz.
Highly linear adjustment, as well as provision for setting the maximum and minimum vibration limits complete the list of main features embodied in the series E controllers.
Vibration regulation is through external potentiometers and on/off type control with external low power contact for weighing and batching system.
Voltage compensation up to 10 percent (constant voltage due to change in input voltage and automatic cut-off for in case excess current is drawn) is available.
Model Elscint 06 offers 20 percent voltage compensation and is highly stable.
Other Models on offer include frequency controllers (Fre_01 and Fre_02) which among other things guarantee constant voltage and constant frequency.
These are of tremendous value in case of intermittent usage of Genset.
Series CV (Constant Voltage) regulators are available where along with the constant voltage requirement, there is a requirement to use a PLC to control the amplitude instead of an external potentiometer.
In all the above models, two potentiometers are provided, so that one is used for coarse adjustment and one for fine adjustment.
These are of tremendous use in weighing and batching systems.
All circuits are CE marked and can either be supplied in a housing box or for OEM machine builders circuit boards can be supplied for integration into their own control panels.
