Press Release Summary = SAPCON'S 'VIBROSONDE' (Vibrating Rod) level limit switch consists of a cylindrically shaped coaxial resonator which is kept vibrating at its natural frequency by piezo-electric elements.
Press Release Body = When one of the vibrating elements is covered by the material, the mechanical vibrations are damped. This damping is sensed electrically and the signal is used to cause a relay to change state. The base of the 'vibrosonde' is relatively insensitive as compared to the tip, so moderate amount of material buildup from vessel wall to base does not affect operation.
Vibrosonde involves simple installation and neither has moving parts nor requires maintenance. It has a long life. The operation is not affected by electrical properties of material and moisture content. Only one vibrating element in contact with the material increases reliability and has a Field selectable fail safe mode.
SAPCON 'VIBROSONDE' is suitable for high and low level limit control of free flowing powders and granules. It is particularly suitable for low bulk density products. It can be used for the control of filling and emptying cycles. Typical applications include plaster, cement, chalk, paper scrap, washing powder, gravel, coal, plastic granules, sugar, milk powder, cereals, flour etc. it can be used for aggressive materials and for applications wherein different types of material are processed in the same vessel.
