Đo tốc độ YOYIK Speed ​​measuring instrument WZ-3C-A

The speed monitor WZ-3C-A can receive input signals from eddy current, magnetoelectric, Hall, photoelectric sensors, etc., continuously measure and monitor the speed and direction of rotation of the machine, and provide overspeed and reversal protection monitoring for rotating machinery. . It is also a smart instrument based on high-performance embedded chips, digital processing technology, and parameter setting can be completed directly through the instrument panel keyboard.
Electrical characteristics:
Power supply: AC85～265VAC, maximum power consumption is 15Watts.
Fuse rating: 250V/0.5A, self-restoring fuse.
Instrument output power supply: provides two channels of sensor working power supply; each channel has a maximum current of 35 mA;
negative voltage power supply: -24VDC±5%, positive voltage power supply: +12VDC±5%; (Default)
Display mode: ultra-bright industrial 0LED display
Measuring range: 0~99999r/min (digital programming to set as desired)

Signal input: Can be connected to eddy current sensor/magnetoelectric speed, Hall speed, photoelectric speed sensor, etc.
Can be connected to two eddy current sensor inputs to monitor reverse speed (A channel speed monitoring, B channel direction judgment);
Can be connected to two Hall speed sensor inputs to monitor reverse speed (A channel speed monitoring, B channel direction judgment);

WZ-3C tachometer has the following advantages:

1. Fast display: The continuous changes in the unit's speed can be observed in real time on the display screen. 

2. High-speed memory: The instrument can display the speed that the instrument has memorized since the last reset.

3. Flexible settings: Users can set and modify instrument parameters on their own computers through the provided software according to the actual conditions on site.

4. High-precision current output: The 4-20mA current signal has an output accuracy of up to 0.2% FS within the full-scale range, a load range of 0-1kΩ, small temperature drift, and strong stability.

5. Communication: The communication method is RS232 serial communication. The instrument transmits data to the host computer in real time. The user can remotely collect the real-time measurement values ​​of the instrument through the host computer.

6. Alarm output: Careful circuit design ensures that the action of the alarm relay output is reliable and correct.
