SD30-KA is usually used to detect object with lower speed. When the speed of the object is lower than the rated speed,the sensor output an open signal. Note:When the power is supplied,it takes around 9 seconds for every kind of speed sensor to enable the detector to keep pace with the detected machinc,ln fig.1 it is detecting the broken link. 調(diào)整 開關(guān)使多圈電位器進行調(diào)整，順時針旋轉(zhuǎn)頻率增加，逆時針旋轉(zhuǎn)頻率減少。 Adjustment The sensor uses a multi-turn potentiometer to do adjustment,clockwise turning to increase the frequency and counterclockwise turning to decrease the frequency. | |
