hi
i need some kind of sensors to detect the current and give a digital feedback to the plc.
i'll explain u the application. the plc has been installed on a furnace and some feedback is needed in case of heating element failure. this feedback needs to be immediate and so using temperature sensors is not a good idea. i believe the most suitable feedback would be to sense the current on the three phase supply of the heater and so as soon as the element fails there wont be any current flow and hence the failure may be detected.
could any one please give some information about this.
