More than 3000 hours operation time
Maximum stroke reduction of 8%
Process Development Engineer Lars Gjødvad has conducted the study and explains:
- We saw a maximum decrease in stroke of 8%, which is excellent. Measurement uncertainty is estimated to correspond to approximately 3%, so a max stroke reduction of 3 times the measurement uncertainty is indeed acceptable.
Capacitance less than 6% difference
Changes in capacitance as function of elapsed test time are less than 6% difference from “as produced” values. Depending on conditions use, capacitance decrease on the order of 5-15% could be anticipated. Measurement uncertainty for the capacitance measurement would correspond to 0.01% which must be regarded negligible.
Lars Gjødvad adds up:
- All in all, Noliac multilayer actuators show excellent reliability. Operation in excess of 3000 hours or 1*1010 cycles is absolutely satisfactory and confirms the fact that we produce multilayer actuators of very high quality and reliability.
