Dry reed switch + temperature-sensitive level gauge – how to set the range for temperature variation
Thread Content
1. Teachers, there is a domestic float level gauge on site – a level gauge that uses reed switches along with temperature sensing. How should the range for temperature detection be set? 2. Which teacher has seen the manual for this type of instrument? It’s an equipment imported from Germany, with four wiring terminals. From what I’ve checked, it seems to be a float level gauge. Could these four wires function as those of a four-wire thermal resistor? Is it necessary to use a temperature sensing module in order to use it?
The DCS is now an AI node; it’s not clear whether it’s a level gauge or a switch
It is possible to disconnect the connection to the DCS in order to stop powering the instruments; a multimeter can be used to test the instruments on site. If they are switches, there will be a change in conductivity during testing.
