Description
technical field [0001] The invention relates to a large-scale rotating machinery monitoring device, in particular to a large-scale rotating machinery bearing temperature alarm monitoring device. Background technique [0002] The large-scale rotating machinery bearing temperature alarm monitoring device in the prior art has complex circuit structure, many components, bulky volume, high production cost and is not easy to manufacture, especially when the large-scale rotating machinery rotates too fast, the temperature of the bearing will rise , The bearing temperature exceeds the allowable value, which is easy to cause damage to the equipment. The large-scale rotating machinery bearing temperature alarm monitoring device in the prior art monitors and alarms the bearing overheating, either only has an audible alarm, or only has a flashing alarm, and the warning effect of such a monitoring and alarm device is not strong. Contents of the invention [0003] The object of the pre...
