High performance piezo stacks in a hermetically sealed metal case. This product was developed for uses which requires the highest demands for reliability and efficiency. Easy assembly in customer application is fostered by integrated pre-stress mechanism and different flange versions for easy mounting.
The filling with inert gas keeps the piezo stack inside in dry condition. Long life and reliability is assured as water is excluded fro the inner atmosphere.
The steel container surrounds the ceramic body to prevent the penetration of gases especially humidity effectively.The steel cover establish an efficient barrier against gas penetration. Water is kept away from the ceramics stack which results in long life.
The elastic design of the steel casing ensure free elongation of the piezo stack. As the assembly of corrugated bellows is prestressed,compressive forces act on the ceramics piezo stack and provide compressive stress for long life and high performance.
Different flange designs are available for easy assembly.
Forces from 200 N to 20.000 N (cross area will change accordingly)
Displacement from 17 um to 200um (length of stack will change accordingly)
At the bottom different flanges are available.
