Review: 中古の籾摺り機を購入しましたが、回転計が壊れたため、交換用に購入しました。 回転表示部は、ほぼ同じ大きさで四隅をやすりで少し削るだけで簡単に取付ができました。 センサー部は、配線が短く細いため、既存の配線と接続に手間取りましたが、何とか取付できました。
Review: I bought this to show my lathe's speed. It worked well. A little problem mounting the magnet. Instructions say south pole. I used a magnetic navigational compass to determine north/south of the provided magnet. When I mounted south pole toward the sensor, it didn't work. Turned it around and it did. I epoxied the magnet so unmounting was a nuisance. Connection was simple, just be sure to follow instruction on wire colors. Ground yourself when handling electronics to keep static zero.

*by F***C on 5 January 2019*

Ho acquistato questo contagiri per completare la mia fresa a controllo numerico. occorre fare attenzione ai collegamenti del sensore di hall perché se alimentato al contrario si brucia. Il magnete in dotazione non è particolarmente potente, volendo una distanza di misura di 5 o 6 millimetri ho usato al suo posto un N50 rettangolare 10x5 mm. Attenzione al fissaggio perché un magnetino da un grammo se messo in rotazione a 10000 giri produce una forza centrifuga di diverse centinaia di grammi e schizza via e può far male.
