SDJ-3L vibration monitoring and protection instrument: it can measure the vibration of the casing or structure relative to the free space, that is, the absolute vibration, especially suitable for machines with ball bearings, in which the vibration of the shaft can be more transmitted to the casing Therefore, the monitor can be equipped with a magnetoelectric speed sensor for continuous measurement and protection of rotating machinery. Special attention should be paid to the installation of the sensor so that the sensor amplitude will not be reduced, and the frequency effect will be changed or the generated signal cannot represent The real vibration of the machine is especially suitable for situations where a large number of vibration points need to be measured for motors, compressors, fans, etc. 

Functional description (intelligent type) 1 Realize intelligent processing: Alarm I value and II value can be set arbitrarily through the panel buttons 2 Panel buttons can adjust the range value without potentiometer adjustment, which is convenient for on-site debugging 3 One minute without pressing the operation button, you can automatically return To the running state  4. The alarm delay adjustment range is 0.1~3 seconds to prevent false alarms caused by on-site interference 

5. It has the function of power-on and power-off detection, and cuts off the alarm and shutdown output circuits at the same time, which can effectively suppress the false alarm of the instrument. 6. There are current output terminals
proportional to the vibration amplitude on the rear panel for recording and outputting
