Tachometers and 4-20 mA signals
Tachometers and 4-20 mA signals
(OP)
I am trying to get a speed feedback from a 1 HP AC motor using a simple tachometer. I have look around but the only one I found is one that Dart Controls sells. The device is very simple. It attaches to the end of the motor and give pulses. (the model number is PU-2E for a single pulse per revolution) I do not want to buy a transducer to translate the pulse to 4-20 mA. Is there any other in the market that can give 4-20 mA directly from the tachometer?
Thanks.
Thanks.

In the case of the pulse-output device you have, you would first need a frequency-to-voltage converter, followed by the voltage-to-current converter mentioned above.
