Cologne Optimass 7000 sensor resistance
Thread Content
Dear experts, I would like to ask: the Cologne Optimass 7000 sensor has 15 terminals, and what do these 15 terminals represent? The manual only states that white and yellow correspond to sensor A, etc.
Don’t you have the user manual for this device? If not, ask the manufacturer for one. Additionally, those connections are already welded, so there’s no need for you to make any further connections. By learning the principle of mass flow meters, you can get a general idea of what these connections are used for.
Generally, most mass flow meter sensors include the following wiring: two wires for the excitation coil, two wires each for detection coils A and B or shared together, and four wires for the PT100
