| 摘要 |
<p>The invention relates to a method and a device for monitoring the temperature of a moving member (e.g. a bearing) (3), by means of a signal generated when the temperature of the member exceeds a certain limiting control temperature. The signal is conducted to a central supervisory unit supervising the operation of the moving member. In thermal contact with the moving member (3) is located a thermal release device (10-13) which trips when the temperature exceeds the control temperature. Close to the path of motion of the member a sensing means (4) is disposed, this means (4) sensing when the thermal release device (10-13) has tripped and transmits a signal indicating this to the central supervisory unit. The thermal release device may be a bimetal strip or comprise a memory metal, or alternatively it may incorporate solder which melts to release as indicator which is then moved by a spring or small explosive charge. <IMAGE></p> |
