Intelligent Speed ??Monitor Application of micro processing chip signal processing, measurement accuracy, stable performance, according to the needs of the user extensions. The Monitor has the speed measurement, two alarm, overspeed protection, analog voltage and current output, sensor fault detection, alarm information, self-test functions. For electric power, textile, petroleum, chemical, and other units rotating machinery monitoring and protection. 
 2. The main function 
 2.1 The display has a velocity measurement, the maximum speed 99999 r / min, five digital display. 
 2.2 alarm function, when the measured rate of more than one of the alarm set value, the corresponding front panel warning indicator light, switch on the rear panel output signals, protect the monitoring equipment. 
 2.3 has a voltage and current output interface with computers and other devices. 
 2.4 alarm value, the number of teeth, time can be set through front panel buttons. 
 2.5 Effects on speeding event has storage to prepare for queries. 
 2.6 has a sensor or the input circuit fault indicator. 
 2.7 has a self-test function
