Hi friends;
I am new witth that speed sensor. I want to simulate the speed signal plz guide me how can i simulate it? I have Fluke 741B and frequency counter as well.
The data of Speed probe is as under
60 pulses per revoulation
Supply Voltage +9.5 to + 15 V
Power consumption 40 mA
Tranducer Type MDg 14 Output signal +12 Volt depend on the supply voltage.
Range of working frequency 1 HZ to 30 Khz

The wiring diaggram is attached with it.
Output is suare wave.

I want to ask how and what value of Volt and HZ i give to simulate 5500 RPM.
Function generator have both options square wave and sine wave.
Which one i apply?
Regards

Use the square wave output on the function generator.

It looks to me like your sensor output will be roughly sensor supply voltage - 3V. So set your function generator voltage output based on the expected sensor supply voltage

The frequency setpoint for simulation would be:

5500 rev/min * 60 pulses/rev * 1 min/60 sec to give you pulses/second, or Hertz. Unit cancellation; what a beautiful thing.

I want to run a simulation of a program uploaded from a rockwell PLC, but I can't configure the CPU on the emulate to match the actual CPU.
