摘要:
The wireless sensor adds identification information peculiar to respective sensor modules to detection data of vibration, temperature, and soon, detected by the sensor modules respectively. The wireless sensor transmits the detection data with the identification information as a signal through a communication unit by radio waves. On the other hand, the management apparatus receiving the signal classifies and files the detection data on the basis of the identification information included in the signal. Then, the monitoring system is designed to make the management apparatus manage a plurality of wireless sensors attached to movable shafts of processing machines or the like.

摘要:
Revolution speeds nca, nib of rolling elements 9a, 9b are sensed by a pair of revolution speed sensors 21a, 21b. Also, a rotational speed ni of a hub 2 is sensed by a rotational speed sensor 15b. A sum “nca+ncb” or a difference “nca−nib” the revolution speeds of rolling elements 9a, 9b in double rows is calculated based on sensed signals of the revolution speed sensors 21a, 21b, and then a ratio “nca+nib/ni” or “nca−ncb/ni” of this sum or difference to the rotational speed ni is calculated. Then, the radial load or the an axial load is calculated based on the ratio “nca+ncb/ni” or “ca−nib/ni”.

摘要:
A sensor unit is supported on a stationary ring which does not rotate even when it is in use, and the rotation of the rotary ring can be detected by a rotation detecting sensor held within the sensor unit. Within the sensor unit, besides the rotation detecting sensor, there are disposed other sensors such as a temperature sensor and a vibration sensor, thereby being able to detect the rotation speed and the rotation number of the wheel supported on the rotary ring, and the other car driving conditions.
