Inverter current and viscosity
Thread Content
The company has an inverter used to drive a mixer; the design calls for using the current value displayed by the inverter to determine the viscosity inside the tank. I wonder if this approach is feasible What puzzles me is whether the current changes when the frequency is altered by the inverter, and whether the current can still be used to indicate uncertainty in viscosity. ，，，
Since the viscosity value is low, it is somewhat difficult to convert it into an electrical current in a proportional manner; it would be advisable to discuss this with the instrument engineer.
It probably won’t work; can the current variation of the inverter keep up?
Based on the actual conditions, current, frequency, and viscosity can be used to create a table, which then allows for measurements to be taken. A basic empirical parameter in statistics; it takes a lot of effort – give it a try
It is theoretically feasible, but the debugging process takes a long time; multiple experiments are required to fit a curve. If you have enough time, you might as well give it a try
There’s no point in making judgments – when the viscosity is too high, the mixer won’t rotate. It’s just too sticky; as a result, the current level rises and the machine simply can’t start
Only when the speed is constant can you determine the viscosity based on the current value; it’s not possible to do so when the speed is variable. Because as the frequency changes, the current also changes.
