Hi guys
I need to install a control system for a 2 position dosing valve that will be filling powder into two different vats. What i am going to do is take the signal outputs from the level sensors to determine which vat gets filled as the level sensor starts to read (simple enough). On investigation into this the level sensors are 30vdc and the solenoid that is operating the 2 position valve is 230vac. I have purchased inverters for these 24 volt input to 230 volt output (link attached below). The problem i have is that the output of the sensors which again i have attached a link to below is that they are only giving a 5 volt output to a solid state relay which isn't enough to operate the inverter and also the sensors are NPN NC and only give a 24v voltage when the tanks are full. I obviously want to do the opposite of this so can i just change the sensors to 24Vdc NPN normally open? Will the circuit work as i want it to then?
Also i used this following sensor that i had spare just to test it but it did nothing it comes on and the led flashes on it and i know its working because i tested it twice but it still didnt turn the doser motor on or off is this because it is a PNP type sensor or what?

Thanks guys
