Speedometer Tachometer Speed Sensor Digital Frequency Meter For Brushless Motor

Product selling point；
1: Adopt industrial-grade high-speed MCU, strong anti-interference
2: Stable and reliable
3: Features of wide measurement range and high measurement accuracy
4: Small appearance
5: Widely used
 
Newly developed and tailor-made three-phase DC brushless drive products supporting tachometers, using industrial-grade high-speed MCUs with strong anti-interference, stability and reliability, wide measurement range and high measurement accuracy. The software adopts the leading fully synchronized period measurement method and the measurement range And the measurement accuracy is a more qualitative leap, applicable to all three-phase DC brushless drive boards and drive modules with rotational speed signal output on the market, and the three-phase brushless drive products independently developed by our store have reserved interfaces for plug-and-play.
Two setting buttons on the back and interface line definition
 
Note: This product has reverse connection protection. The default power supply voltage is DC 3.3-5V, and the measured signal amplitude is 3-30V. If this parameter is exceeded, it may be permanently damaged.
 
Features
1. High frequency measurement accuracy, up to 0.01‰ at 25 degrees Celsius, and resolution up to 0.001HZ.
2. The frequency measurement range is wide, 0.15HZ-100KHZ. It can also be customized for ultra-low frequency measurement 0.01HZ-100HZ3. The range is automatically switched from 00.000Hz (R/M to 000.00KHz (KR/M).
4. The working mode can be switched by pressing the button, including two working modes of frequency and speed, and the working mode is saved when power off.
5. The frequency division value can be set by pressing the key. The frequency division value can be 1-99999 and 0.0001-9.9999. The frequency division value is saved when the power is turned off.
6. Beautiful appearance, sophisticated craftsmanship and easy to use.
 
-Display digits: 5-digit LED digital tube (0.36’).
-Display refresh rate: signal frequency> 3HZ: 3 times/sec: signal frequency ≤ 3HZ: approximately equal to signal frequency
-Overflow display: "-----"
-Measurement accuracy: 0.1%±1digit or 0.01‰ at 25℃.
-Measuring range: 0.15HZ—100KHZ. 9r-999.99Kr/m
-Input signal: Type: dry contact, PNP, NPN, pulse Amplitude: 3-30V
-Measurement method: fully synchronized period measurement method.
-Input resistance: 100KΩ/resistive.
-Power supply: default DC3.3-5V, other voltages are needed, large quantities can be customized
-Withstand voltage: AC2000V 1min between the external terminal and the shell.
-Use environment (temperature and humidity): temperature-10℃-＋70℃ relative humidity 25-85% (no condensation),
-Storage temperature: -20℃-+80℃ (no condensation)
-Dimensions (mm): 48*29*18.5 length X width X height)·
-Opening size (mm): 45*26
 
Instructions:
-1. There are three wires on the meter head, the red is the 3.3-5V positive power supply, the black is the ground wire, and the yellow is the signal pulse input wire, which is connected to the device under test.
-2. Speed ​​measurement and frequency measurement mode switch
There are two buttons "M mode" and "S selection" on the back. When the power is on, press the M key once to enter the mode selection interface, and then select 0 frequency plus filter wave test by continuously short pressing the S key, and select 1 speed plus filter wave test. Choose 2 frequency without filter wave test, choose 3 speed without filter wave test, wait 4 seconds without operation, automatically save and return to the just set mode and wait for the measurement state.
 
-Division value setting
In the power-on state, first press the S key once to enter the frequency division setting interface. At this time, the S key is the 5-digit 8-character shift function of the display screen, and the M key is the value increase. Use the S key to select the 8-character to change the value, and then press M Key to change the value, the frequency division value must be within 1-99999 or within 0.0001-9.9999, other values ​​are invalid (short press the S key to move to the rightmost decimal point when it lights up, then short press the M key to open or close the leftmost decimal point , Realize the decimal point setting) After setting the frequency division value, wait for 7 seconds without operation and automatically save and return to the just set frequency division value and wait for the measurement state.
Explanation of the concept of frequency division value: the number of pulse signals taken when the turntable or gear rotates one turn during speed measurement. For example, when an external sensor is used, the turntable or gear rotates one turn to take 1 pulse signal, and the frequency division value is set to 1. If the brushless drive of our shop cooperates with speed measurement, if the motor has 2 pole pairs, then set the frequency division value (2*3=6)6.
 
Precautions：
1. It should be used within the parameters of this instrument and in a normal environment.
2. Set the mode correctly according to actual usage requirements. Set the frequency division value correctly.
3. When connecting a high-voltage signal, please don't touch the chips and parts on the board with your hands.
