  • materjalide kõvaduse mõõtmiseks kasutatav seade, mis koosneb pendlist, mis saab vabalt kõikuda kahel kuulil, mis toetuvad kaetud katseplaadile
  • device used for measuring hardness of materials that consists of a pendulum which is free to swing on two balls resting on a coated test panel
Persozi pendel
Usage examples
  • Persozi pendliga teostatav kõvaduskatse põhineb põhimõttel, et pendli võnkumise amplituud väheneb kiiremini, kui see toetub pehmemale pinnale. Sel juhul pinde/kattekihi kõvadust väljendatakse võnkumiste arvuga, mille pendel sooritab täpselt paigutatud fotosensoritega määratud amplituudipiirides ja elektrooniline loendur registreerib pendli sooritatud võngete arvu.
Persoz pendulum
Usage examples
  • The pendulum hardness test using the Persoz pendulum is based on the principle that the amplitude of the pendulum's oscillation will decrease more quickly when supported on a softer surface. The hardness of any given coating is given by the number of oscillations made by the pendulum within the specified limits of amplitude determined by accurately positioned photo sensors. An electronic counter records the number of swings made by the pendulum.
