Greetings,
I am trying to design a circuit that will turn on an LED every time a pump motor is running. The motor is 24V and the LED will need to operate at 24V as well (I can do the LED portion of the circuit). I just need a way to detect that the pump is running. It is always powered on, but reacts internally to low pressure in the fluid side of the pump, and then powers up the motor to pump more fluid and re-pressurize the fluid side.
It is for my sailboat, and will help produce some warning if a water line below decks lets go while the engine is running and we can't hear the pump running to endlessly replenish pressure in an open line (which happened in my trip to Panama).
Many thanks,
Paul
