Tástáil Brú Hidreastatach Tar éis tástálacha brú hidreastatacha a dhéanamh ag 3MPa/1h, 0MPa/0.25h, 3MPa/1h, agus 0MPa/0.25h, bhí an friotaíocht inslithe idir na croí-sreanga trasducer agus idir na sreanga lárnacha agus an cásáil seachtrach níos mó ná 100MΩ.
Torthaí Tomhais: Comhlíonann an trasducer na sonraíochtaí teicniúla.
