YD240 hall effect rotation speed transmitter 
A. Overview:
1. YD240 speed transmitter can be used with many output instruments of our company and also can  be connected to magnetic-electric and other speed transducers.
2. The transmitter uses the unique precision measurement method to ensure the high precision of the whole measuring range.
3. It can distinguish the vibration signal from the larger rotor vibration signal effectively.
4. Set 1-1000 pulses each turn freely. Level 2 alarm control the relay output,  the alarm control mode can be flexible setting, all parameters can be set by RS485 communication.
5. Measured value convert to 4~20mA analog output.
6. Imported integrated circuits, filter components strictly; 100% the whole aging and testing to ensure high reliability of the transducer.
7. There is communication interface to connect with the computer.
8. The shell of transmitter is made of aluminum. In order to shield interference from outside, the shell has been connected with the signal ground in the transmitter. Both the mounting plate and the guide rail cassette are engineering insulation plastics, so it can isolate the transmitter and the earth when install the transmitter.
9. Boundary dimension: 78mm(W)×61mm(L)×65mm(H)(base plate mounted, it is compatible with YD9800 of our company and 3300XL of BN company); 90mm(W)×35mm(L)×70mm(H)(guide rail mounted, it is compatible with 3300XL of BN company). Installation dimension: base plate installation 51mm×51mm, use four M4×12 GB29-76 bolt to install; guide rail installation, can be easily installed on standard 35mm guide rail.

Speed adjustment coefficient
Speed measurement value may have some errors with the actual speed value, by setting speed
adjustment parameter can correct the errors.


Filter coefficient
If there are large fluctuations measured values by various causes in the measurement process, set the filter coefficient appropriately can make it stable.



Threshold voltage
In some applications, the duty cycle of the signal that picked up by speed sensor / transducer / transmitter is very small or very
large, and there is big shaft vibration on the shaft, then adjust the parameter can obtain the best
threshold voltage.



Limiting threshold voltage
Limiting threshold voltage can improve the anti-interference ability of speed measurement. When the
limiting threshold voltage is larger, the anti-interference ability is better. But the limiting threshold voltage
is restricted by speed signal, when the speed signal has a large range, you can set a larger limiting
threshold voltage.



Alarm delay time
Alarm delay in unit of second, in 0 ~ 10 seconds can be set.
