FAQ
How does the MPD system handle sample dielectric breakdowns during high-voltage polarization?
Safety and hardware protection are critical priorities. Each of the four channels on the MPD system features an independent high-voltage output equipped with dedicated breakdown current protection. If a sample experiences dielectric breakdown, the system triggers an immediate alarm and automatically cuts off the voltage output for that specific channel. This prevents instrument damage while allowing the other channels to continue operating completely without interference.What specific polarization modes are supported by the MPD series?
To accommodate diverse piezoelectric research requirements, the system supports three distinct polarization modes: ramp-up polarization mode, step voltage polarization mode, and step voltage pulse polarization mode. Researchers can easily configure these settings and visually monitor the entire polarization process, parameters, and states in real time through the intelligent display.What are the maximum sample sizes and materials used for thermal insulation?
The intelligent oil-bath fixture accommodates robust piezoelectric ceramic samples up to 50 mm in diameter (φ) and 10 mm in thickness (d). To ensure ultimate electrical and thermal stability under extreme conditions, the system utilizes premium insulating materials, including 99% alumina ceramic and polytetrafluoroethylene (PTFE).
