Piezo Chopper
Part Number:
RCH1-005
(100 Hz Chopper)
Price
The Piezoelectric Chopper consists of a stainless steel shutter attached to the tip of a stainless steel blade which is made to resonate by exciting the piezo bending section. The 100 Hz piezo chopper requires an oscillating drive voltage matched to the resonant frequency of the chopper blade. This may be provided by a frequency generator and amplifier or an inverter drive circuit such as the EIN-407. Drive voltage may be applied to both piezo layers, or to one side only, allowing the other piezo layer to be used for position or frequency feedback.

The piezo chopper is small, lightweight, reliable, and cost effective. It produces negligible heat (making them ideal for sealed enclosures), negligible EMI, consumes low power, and operates over a wide temperature range.


Piezo Chopper Kit
Part Number:
RCH1K-005
(100 Hz Chopper Kit)
Price
The Piezoelectric Chopper Kit includes one 100 Hz piezo chopper and one 50 - 150 Hz Inverter Drive Circuit (P/N EIN-407). The inverter circuit delivers a periodic output signal to the chopper when a DC voltage is applied to the input of the inverter. (If feedback voltage is desired, the Inverter Drive Circuit can NOT be used to drive the chopper).
SPECIFICATIONS     Values to be used as guidelines.
Driving the chopper with the Inverter Drive Circuit, PN: EIN-407.    (If one side is to be used for feedback voltage, the Inverter Drive Circuit can not be used.)
