<P>PROBLEM TO BE SOLVED: To provide a rolling device with a sensor capable of precisely transmitting a signal of the sensor which has detected a rotational speed, temperature and vibration of the rolling device to a controller or the like installed at a position distant from the rolling device. <P>SOLUTION: A vibration sensor 13 of a sensor unit 1 detects the vibration of the rolling device in a vibration detecting portion 131, and converts it to a PWM signal having a pulse width corresponding to a level of the signal detected by a PWM circuit 132. A temperature sensor 14 detects the temperature of the rolling device in a temperature detecting portion 141, and converts it to the PWM signal having the pulse width corresponding to the level of the signal detected by a PWM circuit 142. The PWM signals of the vibration sensor 13 and the temperature sensor 14, and rotational speed detection signals comprising pulse sequences of rotational-speed sensors 11 and 12 are transmitted to a controller 3 through a multi conductor cable 2. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
