TK-3 Proximity System Test Kit imatsanzira kugwedezeka kwa shaft ndi malo owongolera oyang'anira a Bently Nevada. Imatsimikizira momwe magwiridwe antchito amawerengera zowerengera komanso momwe ma transducer akuyandikira. Dongosolo lolinganizidwa bwino limawonetsetsa kuti zolowetsa za transducer ndi zowerengera zomwe zimatsatira ndizolondola.

TK-3 amagwiritsa ntchito zochotseka spindle micrometer msonkhano kuyang'ana dongosolo transducer ndi udindo polojekiti masanjidwe. Msonkhanowu umakhala ndi chokwera chapadziko lonse lapansi chomwe chizikhala ndi mainchesi kuyambira 5 mm mpaka 19 mm (0.197 mpaka 0.75 mkati). Phiri limagwira kafukufukuyo pamene wogwiritsa ntchito akusunthira chandamale kupita kapena kutali ndi nsonga ya kafukufukuyo muzowonjezera zovomerezeka ndikulemba zomwe zimachokera ku Proximitor ® Sensor pogwiritsa ntchito voltmeter. Msonkhano wa spindle micrometer ulinso ndi maziko osavuta a maginito osavuta kugwiritsa ntchito m'munda.

Oyang'anira ma vibration amawunikidwa pogwiritsa ntchito mbale yozungulira yoyendetsedwa ndi injini. Gulu la swing-arm lomwe lili pamwamba pa wobble plate limapangitsa kuti proximity probe ichitike. Msonkhanowu umagwiritsa ntchito chokwera chapadziko lonse lapansi, chofanana ndi chomwe chimagwiritsidwa ntchito ndi gulu la spindle micrometer. Pogwiritsa ntchito absolute scale factor of the
proximity probe mu conjunctio n ndi multimeter, wogwiritsa ntchito amasintha kafukufukuyo kuti apeze malo pomwe kuchuluka komwe kufunidwa kwa kugwedezeka kwamakina (monga kutsimikiziridwa ndi peak-to-peak DC voltage output) ilipo. Palibe oscilloscope yofunika. Wogwiritsa ntchitoyo amatha kufanizira kuwerenga kwa vibration ndi kuyika kwa siginecha yodziwika yomwe imawonedwa ndi kafukufuku wapafupi. Chizindikiro chogwedezeka pamakina kuchokera ku TK-3 chimatha kuchoka pa 50 mpaka 254 µm (2 mpaka 10 mils) pachimake mpaka pachimake.
