CW/CCW Rotation Monitor
● Rotational speed measurement value, alarm values, function information is show on the display window. Instruction light of different color on the panel coordinate with instrument measurement status give signals
● Proving one stop alarm set point, users can set the stop alarm value of the rotational speed by themselves, and meanwhile the instrument light on the panel can instruct the “stop” alarm, wiring terminal Provide relay output.
● Instrument function using and parameters can be set by the key on the panel; it is smooth operation, convenient and quick.

Product Introduction
The instrument is both for speed measurement, display, and also for speed and reverse warning alarm.When one of the two input sensors fails, it will automatically switchto another sensor to measure the rotational speed, and in the meantim0.e make a alarm instructions (point out which direction of the sensor is failure), and automatically block reversal protection relay malfunction.
Measurement Rang Selection:
Sub-file option is available within 0 to 9999 rev / min speed range, user can have the instrument custom-made while selecting instrument and factory will preset the meter.
Display Function:
Rotational speed measurement value, alarm values, function information is show on the display window. Instruction light of different color on the panel coordinate with instrument measurement status give signals. Within full measurement range, the accuracy of the measurement exceeing 1%.
Alarm Function:
Proving one stop alarm set point, users can set the stop alarm value of the rotational speed by themselves, and meanwhile the instrument light on the panel can instruct the “stop” alarm, wiring terminal Provide relay output.
Reverse Alarm Function:
Provide a “reverse rotation “alarm set point, when the machine reverses, the instrument will alarm at the first time, and instrument light on the panel will instruct “reverse rotation “alarm, wiring terminal provide relay output.
Alarm Reset Function:
When alarms, alarm reset is divided into self-locking and automatic reset; while self-locks, alarm status keeping all the way, “reset” key should be pressed after monitoring status is normal, while self-reset, alarm status will relieve automatically after monitoring status is normal. Users can select one of the ways while selecting the instruments
Self-diagnostic Function
Any input system breakdown, like probe break, wiring fault can be detected, while one of the wiring of the two input sensor breakdown, it will automatically transfer to another one to measure the rotational speed, it will issue a warming indication at the same time (point out which way of the sensor go wrong), to avoid error action for reverse protection, it will automatically cut off reverse protection circuit.
Sensor Power Supply Current Limit Protection:
If the sensor power is short circuit in the course of usage by accident, current limit ≤ 30mA,it will not produce sparks and it suitable for the safe requirement of flammable and explosive occasion.
Record Output Function :
There are 4~20mA analog signal output on the wiring terminal, measurement range which corresponding with the record output can be set in parameter setting function.(F2), users can adjust by themselves, output terminals are designed with short circuit protection function.
Pulse Output Function:
Pulse Output is 0~5V square-wave signal， pulse output equals per minute revolutions of the measured staff multiplied by the gear amount of the measured gear tray .
Speeding and Reverse Rotation Alarm Response Time:
Speeding and Reverse Rotation Alarm Response Time is very fast, response delay time <50ms.
Parameter Setting Function:
Instrument function using and parameters can be set by the key on the panel; it is smooth operation, convenient and quick.

Features and Advantages | |
● There are 4~20mA analog signal output on the wiring terminal, measurement range which corresponding with the record output can be set in parameter setting function.(F2), users can adjust by themselves, output terminals are designed with short circuit protection function. ● Pulse Output is 0~5V square-wave signal， pulse output equals per minute revolutions of the measured staff multiplied by the gear amount of the measured gear tray . ● Any input system breakdown, like probe break, wiring fault can be detected, while one of the wiring of the two input sensor breakdown, it will automatically transfer to another one to measure the rotational speed, it will issue a warming indication at the same time (point out which way of the sensor go wrong), to avoid error action for reverse protection, it will automatically cut off reverse protection circuit. ● Highly intelligent, all functions enable full board operation. ● The measured value and alarm set value can be displayed on the LED digital tube. ● When the alarm set value is exceeded, the alarm indicator lights up and the switch signal is output on the rear panel to protect the monitored equipment. ● It has a current output interface, which can be connected with computers, DCS, PLC systems, paperless recorders and other equipment. | |
Applications | |
The YD470 positive and negative Rotation monitor has a reverse alarm function. It can measure the forward and reverse rotation speed, speed and linear speed of the axles, gears and racks of various rotating machinery such as industrial water pumps. Suitable for the design of the rotating mechanical device TSI, it can be widely used in electric power, machinery, chemical, metallurgical and other industries. Monitoring and protection of the rotational speed of rotating machinery such as steam turbines, coal mills, fans, reducers, pumps, centrifuges, balancing machines, and air compressors.Provides measurement of various parameters and prediction of early faults for the safe operation of rotating machinery. | |
